Having been mentioned as complete only once on this list in passing, and hidden

It's amazing! Only the resolution difference signals that it's not the arcade

Thanks to some generous relatives, I have had my Sam shipped over from the UK 
to the USA (where I now live).

Voltage is not a concern, step up converters are cheap on Amazon. But I would 
like to be able to display the image from the Sam on my TV and unfortunately 
SCART sockets were never put on American TVs.

What would be the best option for converting the SCART to an HDMI connector? 
Would something like this be OK?

RE: Line interrupts

[Adrian Brown]

I always run with a standard Rom replacement system so use IM mode 1.  Stick
a JP at $38 and handle the interrupt that way.  It depends if you need to
use the system ROM, but if you don't always consider running your code as a
rom replacement, it also gives you the RST vectors for faster calls for
standard functions.  If you want I can send you a basic setup for this,
including an interrupt handler

Set up an IM2 vector table, use the frame interrupt to set up the first line
interrupt (send the line number you want to fire to port $f9), then have
your line interrupt routine set up the second time it should trigger by
sending the new line number again to port $f9.

 

I do that more or less for my special edition version of lost disks of sam
I've been tinkering with for a while now, only inside an IM1 interrupt
routine. Seems to work absolutely fine so far, although I don't know if it
would be considered the right way. Probably not, but if it works, I'm
happy as larry.

 

Happy new year:)

RE: Windows Tools for Sam

Pro motion is great, it has similar things but you can also set up RGB
channel bit depths, max colours and if you want to do mode 1 stuff you can
even set block size and colour limits (so you can set 8x8 to max of 2
colours).

Hi Andy,
  
I've always used Paint Shop Pro v7.04 - setting the canvas to
256x192 and 256 (byte per pixel) colour mode.  Then make sure you only use
the first 16 palette entries (in Paint Shop Pro) when you design your
graphics.  These 16 entries will then map directly to the SAM's 16 palette
colours.
  
When you come to save the image save it as filetype RAW and make sure you
set the header bytes to zero.  This will spit out your image as a simple
byte-per-pixel, linear 256x192 block of data of 48k in size.
  
So, for example, if the first 5 pixels of your image used palette entries 1,
12, 3, 9 and 15 the first 5 bytes of the RAW data block you saved from PSP
would look like (in HEX):
  
01 0C 03 09 0F ... and so on.
  
Then you can either write a simple PC program to take these bytes and
combine them to produce the required nybble-per-pixel layout of the SAM, or
you could import this block using SimCoupé and write a simple SAM program
to to this conversion.  After conversion the above example would look like
(again, in HEX):
  
1C 39 Fx (where x would be whatever the 6th byte was in the RAW)
  
The disadvantage to this method is the palette information isn't saved with
the RAW image data.  So you must hand-build the CLUT on the SAM from
whatever 16-colours you decided to use in Paint Shop
Pro.   An extra step, but not too troublesome.
  
If you try this method be sure to find a version of Paint Shop Pro that is
=7.04, as all version after that sucked big time!
  
Chris.

 That's a pity, it's your right of course, but I think you are

 Allowing emulation may get some odd sods, myself included, wanting to 
 write something for it, resulting in enough momentum for it to become 
 interesting for a real SAM user, resulting in a sale for you. Sounds 
 like egg and chicken basics to me.

I agree with you, Stefan.

Creating software and hardware for the real SAM is great and desirable, but
emulation is the way most people can use, program or even meet a SAM.

In my opinion, emulating a good interface is an avail for its seller and for
the real machine users, because the interface becomes potentially more
useful, and more desirable.

Am starting to poke about a little more with Coupe development as time
permits and I wondered what, if anything, currently exists by way of
publicly-available cross-development tools. I have my favourite text
editor and pasmo set up, which I use for occasional speccy stuff, and
have augmented this with pyz80 (coz it writes out DSK files, which has
been handy). Have also got SAMdisk and DiskManager for manipulating disk
images, which seem to be working nicely, but...

What I really could do with is a utility (preferably with a palette
editor) for drawing graphics (tiles, sprites) that runs on Windows and
spits out either DEFBs or binary files that I can INCBIN. Does such a
thing exist? Failing that, something that has a reasonable stab at
converting PNGs or GIFs into a form I can use in asm would be useful.

What do you guys use to do this sort of stuff? And also are there any
other useful cross-development tools that I should be looking at?

Cheers,
Chris.

I'm currently partway through The ZX Spectrum ULA: How To Design a
Microcomputer, which is the book partly researched by photographing and
reconstructing the exact IC layout of the Spectrum's ULA. So it goes
into a lot of detail about how ICs were produced in general, the nature
of ULAs, the Spectrum's design constraints, how they therefore ended up
laying things out and all that sort of stuff. As someone who has
previously looked no lower than product data sheets it's fascinating.

Does anyone know of any similar sort of details about the Sam's ASIC?
Presumably it's a similar process - application-specific interconnects
added to a generic, previously manufactured base - but benefitting from
seven years of advances in density? Though the Sam's design process
seems to have been quite extended, so maybe they used some other
process?

I guess nobody has the resources to have photographed one but what
documentation do we have? Google's not turning much up.

The best idea I've come up with is to use a very limited number of tiles and 
scroll like one of those infinite ball demos.

 

So, you have 8x8 tiles and 8 screen buffers. You scroll only either 1 or zero 
pixels at a time, only ever in one direction. Assuming it's a right to left 
scroll, for each movement you switch from one buffer to the next. Then run 
through each on-screen tile and paint only if that tile is not the same as the 
tile one position to its left.

 

With a small number of possible tiles and a normal sort of platform game layout 
(ie, lots of horizontal platforms) you shouldn't have to draw all that much. 
Level two of Super Mario Brothers would probably be an ideal usage case.

 

I guess that the next thing would be to store your tile map as the computed 
list of tile changes to draw per tile column, and to consider whether compiling 
your tiles so that you map from the combination of old tile and new to the code 
and draw only the changes gives a meaningful boost for the memory cost.

 

I'm not sure whether anybody else has done this sort of thing, but I really 
mean to give it a go sometime soon.

I'm currently using the delta-update (only printing the changes) in XOR to get 
192*192 pixel scrolling.  It doesn't go at 50 frames per second, but looking at 
the C64 version of Sanxion, that's obviously not running at 50fps either:

http://www.youtube.com/watch?v=WDg1GX37bkUfeature=related

For example, at about 1m35 the bonus level bullets are obviously skipping out 
lots of frames to get a good speed.  The mountain level before that, looks like 
the scrolls are going 16 pixels per update, which looks like 25fps at most.

But I think most people forget that full screen scrolling never went at 50fps 
on 8 bit machines.  Even the ST struggled, and the Amiga only managed it 
because it had the blitter.  If you want to convert it, just go with whatever 
you can get away with!

held (max speed but video capped at 5fps).

The OpenGL version ran very slowly in X, as though it was missing
hardware acceleration.  That will be needed for the 5:4 aspect ratio
feature, to make it look more like the original display.

There wasn't any sound from the 3.5mm jack, and I did see some warnings

a damn good root around! Simcoupe itself is bundled with what I would
call the best stuff, but you'll need a few things to port the PC images
back to real floppies, namely SAMdisk (by Si Owen) and a PC with an
INTERNAL 3.5 floppy drive (external won't do).

Also have a good look round Andrew Collier's Intensity site because
there's loads of great bits locked away.

As for other stuff to get, I'd advise the Atom HDD, Stratosphere,
Defender, Momentum, Lemmings, Protracker, E-tracker, SAMpaint, GI-mon,
Comet, Pyz80, some kind of SAMdac or EDDAc, SAM mouse, and every
diskzine you can get your hands on!  There's just LOADS of great stuff
available.

Ok, to change the topic from current discussion lately ;-)

I am a newbie to the Sam world, I bought a machine on ebay as a whim and
to reach one of my childhood dreams of owning one. As a kid I could not
afford one and by the time I had $$$ Sam had dissapeared and it was time
for Uni.

So I now have this lovely Sam Coupe with 1.5 working drives and 512K of
memory. What games/demos/widgets should I be getting for it. Would be
good to give this machine as much love as my collection of spectrums and
zx81 get!

 I was drawn by the possibility of there being something new and 
 unimplemented, though it's sounding increasingly unlikely.

 Still, I think your suggestion should be relatively easy to try, just for 
 fun!  Just a single byte offset for the start address?  How should wrapping 
 be handled?   I'm in the middle of a sound revamp at the moment, but I'll put 
 it on the list to take a quick look after that.

I was thinking a full two-byte offset with a rolling window.

So normally ASIC looks at the VMPR for the RAM page, then (I imagine) keeps a 
15-bit offset from 0 and reads byte-by-byte, incrementing offset as it goes 
(obviously doing weird stuff for mode 1, but I'm
simplifying)

If you could just change that 15-bit offset to start at XhXl using

LD B,Xh
LD A,Xl
LD C,MyPortNumber
OUT (c),A

hardware scrolling, the cheap way. I think the BBC did exactly this.

 Would that be possible with a real SAM peripheral?  Can the value on the bus 
 be changed to redirect the display read?  Or is it possible to modify the 
 value read instead?  Perhaps something that watched for display reads and 
 cached the values, so it could supply a remapped value to offset the display?

Uhh. I doubt it. The ASIC handles the value being read, so unless you can a) 
tell the difference between a normal address request and an ASIC request and b) 
either override that address or at the very least override the result that came 
back.

I don't even think the ASIC memory requests appear on the bus, do they? Colin 
would know :)

Well not exactly, because the decompression takes place once a level, after

RE: Dizzy (was:Porting spectrum games...)

[Adrian Brown]

Yer LZMA is a nightmare, I didnt do all the work on it, its from a project I 
worked on with others.  But its a LZ77 style as you say that has differing ways 
of encoding the length and offset, this increases compression by not always 
having to use the same number of bits for the length and offset storage.

Everything is bit range coded using markov chains but its all interleaved.  
Basically everything is sent to a bit encoder which works out a probability of 
it being a 1 or a 0 based on arithmetic encoding style of subdividing a global 
range.  Everything has its own probability which is updated following each bit. 
 So decoding it starts by checking whether its a literal or lz77 by decoding a 
single bit from a bitdecoder.  Reading that bit updates the literal/not bit 
decoder probability ready for next time.  If its a literal then it decodes and 
updates the literal bit probabilities in turn.

It doesnt have to transmit probability tables as they are calculated on the fly 
working on the theory that as long as the encoder and decoder agree on how to 
update the probability based on the bit (i.e. the encoder updates the 
probability based on the 1/0 after it encodes it, then the decoder can do the 
same as it will have decoded the bit so it knows if its a 1/0 to alter its 
probability).

As i say, i know the theory and how the code works, but i didnt write most of 
it.  Im looking to update it so that it works on nibbles and has smaller ranges 
more suited to Sam.  Also I looked at redoing the decoder but most of its is 
hardcoded to 32bit maths, even though its mostly shifts and multiplies, 32 bit 
is not nice in z80.  So ill rework it into mainly 16bit.

LZMA doesn't seem to be terribly well documented, but I'm curious so
do you mind if I ask a few questions?

The LZ77-style stuff is quite well documented on Wikipedia, with
variable packet sizes but otherwise unremarkable. Though it looks like
length of repetitions is limited to 273 at most and the maximum
distance isn't particularly clear. I guess for Sam screen purposes,
273 is more than enough and 15 bits for distance is always more than
enough, with fewer bits being an option?

Then there's the range coding aspect. It looks like the individual
LZ77 packets are range coded and the fixed values encoded in literal
packets are range coded separately? So you end up with two streams and
you follow the LZ77 stream, grabbing a decoded digit from the data
stream whenever you hit a literal packet?

There are vague references to context and Markov chains without much
exposition - I've taken this to mean that you've not just one table of
symbol probabilities, but you divide them into groups and each group
uses a separate table of probabilities recording what may come next.
Those probabilities are then used for the range coding. And it's
implied that group membership is indicated by the value of a certain
number of the most significant bits in the normal LZMA course of
things, presumably to make the probability tables cheap to transmit.

Is that all correct? Or even close? It's all much more clever than
anything I was trying.

Oh one thing ive found out that may help in your tests.  Dont compress
the data as nibble pairs.  If you convert the data into bytes (only
using values 0 - 15) then compress that.  (obviously in the decompressor
you need to patch it back so two bytes become one nibble). You may find
you get a much better compression rate.

Oh, but wait! Enabling searching for the best LZ77 window and pattern
size (just in terms of 4 bits, 8 bits, 12 bits or 16 bits - not a

1: 256 x 141 : 4593

Currently a little worse than you for the Dizzys, a little better for
the Flashbacks. I'm going to see if there's anything to gain from
variable length LZ77 regions (at the minute it picks the predictor per
line by trying every predictor with every combination of LZ77 length,
then bundles together all the best predictors into a big block and
LZ77s the whole lot, finding the best window/pattern size afresh for
the whole lot). I guess I can look for patterns in the results of the
line-by-line search.

They're 16 colour (quite poorly in one case), but not necessarily
using colours actually available on the Sam's. I've appended the
correct number of bits to store a Sam palette after the compressed
region.

I've also discovered a bug that makes all my numbers worse. I'm
tapping this on the bus so can't give you actual numbers but it's of
the order of 6.something kb for the first and 7 or 8 for the second.
I'm hoping to be able to shrink again, as right now I'm doing no

Quoting the_wub ! the...@gmail.com:

 It looks better and it means that the off-the-shelf tools for
creating
 screens are substantially more advanced, being things like Photoshop,
 and the skills for creating them are much more widespread. If people

 Further to this: I've been playing around with it today using a couple
 of the more complicated screens from that Amiga map which didn't
 feature the watermark (since it's an alpha transparency, causing the

 makes 141 pixels high). For a sensible lower bound on what I should

 The first (Dylan and a tree) is 5,553 bytes as a PNG. The second

 In my quick dash at compression code, I implemented just a trivial
 little LZ77, using an exhaustive search to pattern match and treating
 each scan line as a completely separate thing to compress (and, as a
 result, rounded up to the next full byte). Five bits for a literal, 17
 for a back reference, the native addressable thing being a nibble.

 From that, I got 6,080 bytes for the first screen and 7,170 for the
 second. And this is without yet implementing a Huffman tree (probably
 best done per screen) or any sort of predictor.

 So, it looks like on a 16 colour display the LZ77 may actually be the
 most of it. In which case it's going to be hard to support the
 conclusion that PNG is massively better than the various common
 techniques when the Sam was a going concern. A Huffman tree is an easy

Annoyingly, I'd presumed this must be impossible!  I treated my Sam to
a Quazar scart cable a while ago but as I have to share use of the
telly it would be very handy to be able to use my monitor as well.

That looks like the right sort of device but isn't there also an issue
with the Sam not having a standard scart configuration?

I prefer rotate clockwise, rotate anti-clockwise and fire for drop -
then i prefer fully re-definable keys ;)

Hey again all,

Despite a fun weekend working on this I still didn't get everything
done that I wanted and there's a little bug that stopped me posting
the new version last night.  I have a rule about not programing after
work but I will see if I can spot just this one because the 1 player
mode is rocking , in my humble opinion :D

I'd be interested to know if people have any preference for controls?
At the moment I have:
Q - Rotate
A,- Down
Z,X - Left, Right
With space to drop the piece, when I get round to adding that.

I was going to use the fire button to drop piece for joystick control,
but would people prefer drop on down?

Just thought it was worth the asking :)

SAMOnline... TCP/IP Stack Update

[Adrian Brown]

Well some good news today.  With help from Colin and also Turbomon (nice
one Simon :D)  SAM not only sends an HTTP GET Request to a web server,
but it also displays the text it receives back from it.  SAM is now
officially online :D.  

 

 There are a few more bits to do, but Colins SAMOnline should be all
linked up very soon, then i need to sort out the interfacing code so
anyone can start writing applications that use TCP/UDP protocols as well
as any online things.  It would be relatively easy to write a basic
email system ;) 

 

A Big thanks to Colin for his amazing Trinity interface, and also for
his patience while i get the stack sorted.

Hi all,

I'm a new member to the mailing list and since there's been some
activity over the last
few days I thought now was a good time to stop lurking and say, hey!
to everyone.

My name is Rob, I'm 32 and live in the south of England.  I'm
currently working as a
panel wirer/wire man for a sub-contracting electrical firm.

I was a speccy user back in the day and desperately wanted the Sam
when it came out.
Long story short, it was too expensive and I ended up with a second
hand Sega Master
system instead.  I still have a Sam scrapbook I put together from
magazine cuttings in the loft
somewhere, and I could (but won't) tell you about a highly
embarrassing letter I wrote
to Bruce Gorden when I was twelve that, to this day, I still cringe
thinking about :)

Last year I won a nice boxed Sam Coupe on ebay with one floppy drive
and a pile of
disks and I can honestly say that life's much better now.  I have lots
to say about
what I missed out on by not having the Sam in '89-'90 but I'll save
all that.  The
important thing is that I've been learning to program z80 since it
arrived and am just
finishing my first, actually playable, game!  I'm sorry that it's
tetris but as a
consolation prize it's a two player tetris on one Sam, loosely based
on the vs mode
from the old Gameboy tetris.

I hope that's enough for an introduction.  I feel a bit like I'm
turning up to a party
20 years late with only a bottle of Blue Nun to show for myself, but
I'm looking
forward to finally getting involved in the community and catching up on
all
those lost years!

RE: SAM's 20th Birthday

[Adrian Brown]

I remember selling my spectrum to part fund my sam and living without a
computer for 5 months running up to the release of the sam before i
could afford one :)  Those were horrible days, but all worth it when i
got the sam - even though it didnt have a disk drive, i could only aford
the tape version.  Defenders of the earth on tape- that was a painful
load :)

RE: Hello to the Sam community!

[Adrian Brown]

I love my trinity - it fits just nicely with my sam in a can - although
i keep a normal sam jsut for having an untouched sam :).  Sometimes i
wish someone could pay me to develope stuff on sam as i never have
enough time for all the things i want to do.  I really didnt want UIP to
take so long - but Colin and I had a long discussion not that long ago
on how to interface it all as its a little compilated to get sorted so
that a) basic programs can use it and b) you dont have to recompile
everything all the time as there are lots of section to UIP.  Just gotta
get it all sorted - ive just got this sodding bug in the http protocol
to fix :)

Watch this space on other things :D

I'll hang on with making a page for it until a good working version is

I'm really itching for Adrian's port of uIP for the Trinity- I'm so
looking 
forward to him squishing the last couple bugs in the code so the TCP/IP 
stack is up and running. Some applications, such as the SAMonline stuff
I'm 
working on, will hopefully be up and running and released pretty quickly

once the stack is able to perform simple fetching.

Also for the Trinity now that I've spent the last few weekends
programming 
to get B-DOS speeded up a bit and the Autoboot done my next task will be
to 
add support for SDHC cards to get 4GB and 8GB cards working.

RE: Hello to the Sam community!

[Adrian Brown]

Hiya,
Yer - I cant remember which Sam Revival had some images from the
emulator after i took over.  Having done some GB stuff before i had a
good insight into the hardware which made it possible for me to fix
several bugs that gave some nice looking screens working.  I stopped
where i needed to add paging etc for 32k roms and also i needed to fix
some cpu core problems, ill get it sorted one day - its just another
thing on my long list.  The uIP is top of the list at hte moment as i
want to get some sort of cross development system working to make life
easier.  Then who knows - the sky is the limit.

There would be no mocking - i was just recalling the way i got into the
sam coding with Colin this evening, we all start somewhere and learn as
we go along.  Alot of people have offered me help along the way,
pointers are always the best, its no good just being handed the answers
on a plate as then you dont tend to learn, but then again its no good
not being given any help what so ever.  I remember calling various games
companies in the late 80's early 90's and asking to talk to their
programmers about how they did things.  Bet that wouldnt work these
days, back then they were happy to talk you through things and what sort
of thing to look into.

Anyway - any questions ask away, post to the list or to me directly - up
to you, if you post to the list then anyone can throw in a comment or
two :D

I read the little blog by the guy that started the GB emulator, if I
remember right the blog stops about where you take over.  I loved the
original black and white GB and would love to see AligatIor Pinball or
Bubble Ghost running on the Sam.

As for wubtris, as it shall be known, when I send images it will be of
my working disk, so the source is all there for the mocking :)
I could ask for help in so many areas I am stuck or unsure with that
it's probably safer for you all if I don't!

 I still believe that people have missed the greatness of the SAM due
 to 16 bit machines becoming dominate at the time of it’s release.

Seconded!


 So to all of us who have got unfinished projects “Let’s get on with it”

I fall into that catagory too time to get Comet out, and to get SAM 
Revival 23 finished off and printed asap.

Quite a few things lined up for SAM Revival and I'm toying with the idea of 
a complete colour issue for a special 20th birthday issue - if I can find 
somewhere to do affordable magazine printing I'd really like to do a one-off 
glossy mag for the birthday - as Sam has never had a 'proper' glossy mag 
during it's life...!

I'm a bit confused about all this - how will this all work from a
technical point of view? I don't know what hardware ethernet
controllers tend to have... presumably the ethernet controller can
self assemble packets, then the z80 will run a TCP/IP stack and the
various HTTP protocol-related tasks? Are you planning to claim well-

Re: the SD/MMC card and reading it on full-size computers, I think
there isn't a solution yet for Trinity-format cards (?), presumably
for us people using an OS with a UNIX layer, this is just a case of
someone writing something to find the correct block device and read it
back in the expected formats, and could even be added to something
like FUSE (the filesystems in userspace one, not the Spectrum
emulator)? How hard would it be to add to Sim Coupé?

 No need to reflash existing Trinitys. The EEPROM on the Trinity is
 both
 readable and writeable from software. It's on there to store settings
 and
 such like for programs (e.g. network configuration). It's allocated
 with
 a
 simple system giving 120 x 1K chunks and a table which has a record of
 what
 is using each chunk. There's all the info on how it stores stuff as
 well
 as
 all the source code needed to do everything included with the Trinity
 (and
 also printed in SAM Revival 20)

 A simple program could be made to allocate a chunk (or chunks) for the
 extra
 boot code or the whole DOS, which the patched SAM ROM could then fetch
 when
 the SAM starts up.


 In fact, I guess you'd just be able to offer the OS ROM as an upgrade
 (?), so I guess I could order a Trinity right now and get myself in
 order with whatever tiny number of discs I didn't long ago image
 while
 the drive is still working.

 Yeap. When it's ready it would just need the modified SAM ROM to be
 fitted
 inside the SAM and then a program loaded on the SAM to dump the extra
 chunk
 of code in the Trinity's EEPROM and then it would be all set to go.


 While the Atom and that ROM would clearly solve my solid-state needs,
 it would be nice to throw some ethernet on in there while I'm
 spending
 the cash.

 I'm itching to see stuff using the Ethernet up and running as you'll
 have
 seen from the latest magazine - I'll update information on my webby of
 what
 I've got in the works at the weekend when I've got some spare time.

 From chatting with Adrian I know he's been making great progress with

Evening,

Just sitting here thinking about about it, it could probably be done a
lot
simpler with the Trinity. For the Trinity, space in the ROM would only
have
to be found to fit in a very small routine to see if the Trinity is
connected and then if it is load an extra chunk of code from the onboard
128K EEPROM into memory.

It would then execute what it fetched from the EEPROM to load the full
DOS
into memory. Although, why not then just go the whole way and store the
DOS
in the 128K EEPROM to save having to fetch that from the SD card.

From what I remember back when I was changing ROM3 for the Mayhem -
removing
the copyright message and coloured bars would possibly be all that's
required to get enough room for the tiny chunk of code to fetch stuff
from
the EEPROM.

Correct.

Having hardware that would mimic the WD1772 for mass-storage would be
overkill I think, and drastically more complex than what's been made to
date.


 It's a shame neither do FAT32 + virtual images, even if it was just
 something like, e.g. having a read-only FAT32 partition on one part
 of the flash and a read/write Sam partition on the rest.

Edwin's done a great job with the B-DOS and it's a very neat solution
for
handling mass storage, that's why I asked him if he would mind it being
patched for Trinity. With such a good DOS there, there was no need to
reinvent the wheel.

I know I have info somewhere for FAT reading, and I've had the odd
letter
asking if the likes of a SD card from a camera could be read on the SAM.
I
had said in reply that I might briefly look at it sometime in BASIC just
for
very simple file transfer and write it for an article in the magazine or
something, but taking it further to a full DOS to use the likes of a
.dsk as
a virtual disk would be a pretty big jump and not something I'd have the
time for, plus I've no real experience of writing DOS stuff on the SAM -
I'm
still really inclined to using the network for transferring... really
itching to get on with things when the stack is ready.

then again is there any hardware for the SAM that uses them? I think it

 This was based on info from a book called z-80 Workshop manual by
E.A
 Parr. The I register gives the high part of the table and the
hardware
 gives the low part to the table then takes that word for the service

 routine. So if you start from one byte before the table and use the
same
 address for all entries and over run it by one it will work. My demo
of
 a full scrolling football pitch used this system, which I believe
you

 Hi,

 I'm sceptical about this claim. I've never heard anybody say that
the
 vector formed is big-endian - it's just you don't know the byte
offset
 from which the interrupt vector will be fetched. (As Edwin says, it
is
 usually 255 - which is odd so your 1-aligned table will usually
work -
 but I don't know that Sam's hardware guarantees this).

 So the high byte comes from I, the low byte from the data bus; this

 forms a 16 bit address which will be incremented once (which is why

 the table needs 257 bytes, not 256). You could, at least in theory,

 read the vector address from even or odd overlapping entries, which
is
 why the usual strategy is to pick a vector address whose low and
high
 bytes are the same.

 The last IM2 interrupt routine I wrote looked something like this:

 ds ALIGN 256
 IM2TABLE: equ $
 IM2BYTE: equ im2table/256

 IM2TARGETBYTE:  equ IM2BYTE+1
 for 257, DB IM2TARGETBYTE

 IM2TARGET: equ 257*IM2TARGETBYTE
 ds IM2TARGET-$

 EX   AF,AF'
 ...

 After a little test and using old brain this is wrong.

 All 8 bits are used for LSB of the vector. The part where bit 0 always
 is
 zero is when one of the Z80's IO chips is connected (PIO,SIO,CTC etc)
 is
 connected.

 I've just been looking at my books. Although I can't find the bit
 that
 said about swapping to high,low but I'm sure that I did read it
 somewhere. It does say that the device only gives the bits 1-7 and
 bit 0
 is always 0 giving 128 possible addresses.

 This was based on info from a book called z-80 Workshop manual by
 E.A
 Parr. The I register gives the high part of the table and the
 hardware
 gives the low part to the table then takes that word for the service
 
 routine. So if you start from one byte before the table and use the
 same
 address for all entries and over run it by one it will work. My demo
 of
 a full scrolling football pitch used this system, which I believe
 you
 saw many years a go.

 Hi,

 I'm sceptical about this claim. I've never heard anybody say that
 the
 vector formed is big-endian - it's just you don't know the byte
 offset
 from which the interrupt vector will be fetched. (As Edwin says, it
 is
 usually 255 - which is odd so your 1-aligned table will usually
 work -
 but I don't know that Sam's hardware guarantees this).

 So the high byte comes from I, the low byte from the data bus; this
 
 forms a 16 bit address which will be incremented once (which is why
 
 the table needs 257 bytes, not 256). You could, at least in theory,
 
 read the vector address from even or odd overlapping entries, which
 is
 why the usual strategy is to pick a vector address whose low and
 high
 bytes are the same.

 The last IM2 interrupt routine I wrote looked something like this:

 ds ALIGN 256
 IM2TABLE: equ $
 IM2BYTE: equ im2table/256

 IM2TARGETBYTE:  equ IM2BYTE+1
 for 257, DB IM2TARGETBYTE

 IM2TARGET: equ 257*IM2TARGETBYTE
 ds IM2TARGET-$

 EX   AF,AF'
 ...

 Mode 2 uses a table with 128 word address but as byte high,byte

 So if you set your org/dump address to ??FF (i.e. ??00-1)

 and then do

   DEFWmode2.i,mode2.i

 so you have 129 words.

 Subject: Attempts at 3d on the Sam?


 Hi,

 I've just discovered pyz80 and am having a fresh bash at some Sam
 projects. As I'm simultaneously working on a Freescape interpreter for
 the PC, my thoughts have inevitably turned to 3d on the Sam, even if
 it means a Freescape-style non-realtime display. I'm therefore curious
 about lots of things, and have a multitude of questions:

 - besides Stratosphere, the F16 demo and that brief gameover bit in
 Dyzonium, are there any other playable segments of games that
 demonstrate 3d graphics? I know there are some demos with bits of 3d
 graphics, but I figure that spending 256 kb on getting the fastest
 possible rotating cube isn't a helpful guide.

 - has it been established whether the animated gifs of Chrome featured
 on http://www.samcoupe.com/preview.htm represents the speed at which
 the game would play on a real, unexpanded Sam?

 - is there any speed advantage to using the ROM routines such as
 JDRAW, JPUT and/or JBLITZ? I appreciate that they are more general
 case than routines that it makes sense to write for a game, but as I
 understand it the ROM is uncontended?

 To be honest, I can imagine that something like Chrome could be done
 with a live update since most of the display doesn't change between
 most frames (it's just a bunch of vertical strips of colour that quite
 often change height and occasionally change colour), and the
 algorithms that are commonly used to calculate scenes such as that in
 Chrome make it really cheap to calculate out a minimal list of the
 required changes.

SR 19 just arrived through my letter box. I really don't want to come

I'm doing some sort of guerilla marketing for Colin... but this is a  
seriously good issue. I'll not spoil the surprise just yet in case of  
what's on the cover and what the new hardware is in case some of you

A quick flip through and the mag seems to have matured into a really  
excellent read with much less Quazar propaganda! Colin knows that  
I've had a go at him several times about better coverage for non- 
Quazar stuff and he's really nailed it with this issue. Lots of  
coverage of stuff from other developers and a whole new article  
series from Adrian Brown which looks fantastic.

If you're ever going to bother to buy an issue of SAM Revival, I  
highly recommend you start with this one.

top

RE: Keyboard

[Adrian Brown]

Ahh - the old sam keyboard membrane problems hit another poor person.
Colin Piggot might have one, check out his website
http://www.samcoupe.com/  he generally has spares, otherwise you can
purchase a ps2 kit so you can use a standard keyboard on the sam, that's
what I had to do in the end.

RE: Sam Revival issue 18 out now...

[Adrian Brown]

Arrived this morning, Another fine issue, Rebelstar screenies are looking 
great.  Hat off to Simon Owen, don't know where you find the time :)

Anyone on the list not getting SR, your missing out, what more can you ask for, 
a top mag, in colour with a coverdisk, get to see lots of things that otherwise 
you would miss.

Nice on Colin :)

Subject: Sam Revival issue 18 out now...

Issue 18 of Sam Revival is now out, and it's a jam packed issue!

Let's kick off with what's on the disk. First up are the three brand new
emulators from Simon Owen which are truly stunning! He's been busy and has
completed his Galaksija and Orao emulators which were announced in the
previous issue. The Galaksija is a Z80 based computer from Yugoslavia, while
the Orao is a 6502 based Croation system so that's using Simon's latest 6502
CPU emulator core. Both are now fully emulated on the Sam and there's a pile
of games on the disk for each system. To finish off his hat trick Simon has
also released an Apple 1 emulator too!

It doesn't stop there! Also on the coverdisk is the latest version of Chris
Pile's Sam Defender, and also Captain Comic - a classic platformer by Lars
Perrson which was first released back in 1994 and was a remake of a freeware
PC game. Wrapping up the coverdisk there's also a demo I've coded up to copy
an old school effect from the Amiga and includes the source code.

Onto the paper side. 40 pages jam packed with news and articles. The
Developer Diary is bursting at the seams with information from Simon about
all three of his new emulators, and there's also the first screenshots of
ISAAC - the port of Rebelstar that's being developed by Stuart Brady and
Warren Lee.

This issue also sees the start of a new programming column. I've looking at
recreating some demo effects from the Amiga on the Sam, and tackle a two
layer tile based scroller.The issue wraps up with the compulsory sprinkling
of Sam Snippets with bits of trivia from the Sam world. Hope you enjoy the
issue!

This issue of Sam Revival costs £3.99 for the UK, or £4.79 for EU including
Airmail postage. You can also subscribe for three issues at a discounted
price of £10.99 (UK) or £13.49 (EU) and save yourself some pennies!

It's easy to order - for PayPal payments (or Credit/Debit card through the
PayPal checkout if you dont have a PayPal account) just click on the Buy Now
buttons on the website. Or for cheque and postal orders email me directly
and i'll be happy to pass on my postal details.

Subscribers copies went out in the post earlier this morning, so should be
with you in a day or two.

All the best,

Colin

Domain worldofsam.org

[Adrian Brown]

Just going through my lists of domains and found the world of sam.org
one, i presume that people want me to keep that on the auto renewal
list.  The name servers are pointing somewhere else, can the appropriate
person either email the list (or me in private) with the names servers
so i can make sure they are correct as i seem to have 2 completely
different names for primary and secondary.



Cheers



Adrian

Yer - a list of current projects would be good, maybe a list of 'would
likes' could be games or just routines etc.
