FYI - from the TCP/IP  RT-11 documentation….

   NOTE

 It is possible to install the TCP/IP Package on a 248K
 machine using the DEUNA/DELUA 18-bit (Non Unibus  Map-
 ping)  EU18XM.SYS handler.  This handler requires 7.5k
 bytes for code and packet buffers.  This configuration
 allows  at  most  one networking application to be ac-
 tive.  

That plus there is a light version of the FTP user program provided.


On the other hand, using a DR11-C, DRV11 etc.. with an external Arduino 
handling the IP stack would probably be 10x faster (or more) than the 
native implementation.  I only get about 5-8 Kbytes/sec with a DELQA 
under RT11.

TL;DR: No. As standard 8-inch floppy disks go, only SSSD are useful in an
RX02 drive, even for double-density use (DEC RX02 modified MFM format).


Any standard single-sided single-density (SSSD) 8-inch floppy (IBM 3740
format) will work in an RX02 drive, and can can be used for either single
or double density.  In principle media sold as single-density could be
marginal for DEC RX02 modified MFM format, but I've only ever seen that on
*really* awful quality disks.

A standard single-sided double-density (SSDD) 8-inch floppy will not work
in an RX02 drive, unless some other system is used to reformat it to
single-density. Arguably if one doesn't have true RX02 media, this is the
preferred way to make some, since media certified for standard MFM
double-density should be perfectly satisfactory for DEC RX02 modified MFM
format.

Standard double-sided 8-inch floppies (either DSSD or DSDD) will NOT work
in an RX02 drive, because double-sided 8-inch floppies have the index hole
in the jacket in a different place.  They could be used if one punches an
extra index hole in the jacket, and if double-density, another system is
used to reformat to single-density.

Re: Sperry UTS 40 on Ebay - Statesboro, Georgia

[Dominique Carlier via cctalk]

Strange seller, I do not understand anything, he handed his UTS for ten 
times the price, but in the same time he just sent me a tracking number 
O_o. I do not know what to expect. Will I receive this UTS or not? If 
not, will I get my money back? I do not know. Meanwhile, for the 
principle, I put a nice negative note. But this guy is a little beside 
his shoes.


Going back to the subject, yes you may be right, this UTS 40 looks 
different, I cross my fingers so that it is not completely different (if 
I received the beast). The connectors of the communication board are 
deported to another place but this does not necessarily mean that the 
CPU board is different. The keyboard connector is not visible on the 
photos because it is in a lower place, but here too I cross my fingers. 
I am even wondering if this UTS has a CP/M program cartridge, nothing is 
less certain. This is my ultimate attempt to save my UTS, or at least 
have a comparison machine for my observations, spare parts if this UTS 
is completely dead. I do not have the skills required to detect problems 
too complex in a purely academic way, past a certain stage, I am forced 
to find a reference machine so that my intuition carried by comparative 
tests can direct me towards the possible breakdown.


Concerning your firmware requests if I can help ... Note however that 
regarding my UTS, in the case of the program cartridge there are 8 
eproms without supports, soldered to the card. In some case it should be 
physically difficult to dump these rom.

On the other hand, this isn't the same as your unit, the connectors on the back

I'm sort of annoyed because I bought a UTS 30 keyboard from someone else. It is

If you install the DELUA, don’t forget there is TCP/IP support for RT11 from 
Alan Baldwin at http://shop-pdp.net/rthtml/tcpip.htm 
.

If transfers between RT11 systems is possible and sufficient (ie:physcial to

check out Megan Gentry's RTEFTP package.  She did document
the protocol, but I am not aware of implementations on other platforms.

Are RX02 disks actually special or will any SSDD 8in floppy work? I
know the drives can't low level format a blank floppy, but since RX01
is IBM 3740 and the RX02 can convert between RX01 and RX02 formats,

In my case, this.   The outfit I use has a contract with a freight
shipper and their price for packing, palletizing and shipping is often
lower than my cost when dealing directly with an LTL shipper.

In addition, they're willing to receive palletized shipments and unpack
and help load them into my truck for usually less than $10.

I found out that they also do warehousing for Amazon sellers.

And it's good for local business.

Indeed, I actually discovered it was called NVR by searching for "jumper".

Others have already addressed the signal level issue.  Not a problem.
When I (recently) developed the Arduino version, I checked the current
sink/source current specs to make sure I wasn't going to blow anything up.

I have posted my code (and pinouts) on Google Drive at:

https://drive.google.com/open?id=0B2v4WRwISEQRUUxuNGhZRENvYjQ

Please read the readme files!  ALL of them (except maybe the PC Parallel
port one).

I would not mind comments/suggestions for improvement if delivered
gently, but the odds that I would actually change anything are pretty
small.  Of course, you can do what you want with your copy.  Some of
this code dates back to 1989.

Just today, while transferring an 18,000 block RT-11 logical disk (LD):)
file, I discovered that the Perl PC program that talks to the Arduino
can sometimes report the wrong checksum.  Most of the time it has been
right, but for that file it reported the wrong number, even though the
file did checksum right when I checked it when it got to the PC.  If
that one is wrong, then odds are its partner for sending files from the
PC is wrong, too.

The Arduino code and the PDP-11 code are probably the best places to
look to understand the protocol.  Basically it is a simple fully
interlocked handshake for each byte transfer.  Each block (fixed at 512
bytes) is preceded by a "flag byte".  The startup process has its own
special flag byte.

0x55  Initial Sync
0x22  Data block  (followed by 512 bytes of data)
0x00  EOF

(You can ignore the PC-ParallelPort folder unless you plan to use a PC
parallel port for transfers - it is a lot slower than using the Arduino,
and is old DeSmet C code.  But BE CAREFUL reading this code, because the
PC parallel port hardware *** INVERTS *** some of the signals.)

RE: Freight Shipping

Pete,

I am not sure what class that was. We generally ship with these guys for our 
own products which are much more delicate then an empty rack. So far they have 
been good to us! ;)

Thanks for the suggestions on places to find everything. I will pass it on to 
the seller. Based on the replies it seems as if the S&H is the "correct" price. 
So now I have to talk to the seller and see how negotiable is his price. :D

I guess that another solution is to put a DEUNA or DELUA on the Unibus and
write some small piece of software that initializes it and send and

find out they're not 100% compatible. So, since I was going to have to
modify a whole bunch of old 48T02s, and there are space constraints on some
of the systems, I designed a little module with a CR1225 and crystal to
totally replace the CAPHAT on a 48T02. Here's the writeup:

http://www.glitchwrks.com/2017/08/01/gw-48t02-1

I've got 100x on order, in panels of 10. If anyone is interested in some
bare panels, assembled modules, or complete 48T02 replacements, let me know!

I'll be doing other modules for the 48T08 and probably one to turn a
DS12885 into a DS12887.

Thanks,
Jonathan

The RICM has an opportunity to get a PDP-8/M (built in Maynard, MA) that is
in Canada. I remember that there was a discussion on the procedure here,
but I can't find it with Google.

Can you either point me to the discussion, or tell me what the procedure is?

Many moons ago I got a bunch of computer equipment from Canada.
VAXStations and X-terminals.  The Canadian just packaged them up and sent
them.  They were old enough to be considered valueless from a Customs
standpoint.  I expect a PDP-8 to fall in the same catagory.

Re: Freight Shipping

[Pete Lancashire via cctalk]

$250 for those dimension across the country is a pretty good quote via LTL,
do you know what class the quote was done against ?

As to not being able to strap down, its pretty easy. Go to you cheapie
parts house or if you have a Harbor Freight get 4 web tie downs. 4 if not
long enough for each.

If you can get it to a LTL'ers dock and you know them well enough they will
strap it down for you, might have to hand the guy doing it $10.

Or find a place that ships a lot of stuff and do the same there.

Oh .. and find a place that receives a lot of large shipments and you can
usually get for free plenty of corner and edge protectors.

I haven't had to pay for LTL size shipping supplies in 20 years.

RE: Importing a PDP-8 from Canada

[Jim MacKenzie via cctalk]

As long as any improvements were done in Canada using Canadian parts, it 
wouldn't matter anyway.  Canada is a signatory to NAFTA, and Canadian goods 
(with rare exceptions) are duty-free to the US.

If you have any doubt, call the border station where you plan to import the 
goods, tell them what you are doing, and ask them what they need and if there 
will be any issues with taxes, duties or import permits.  My guess is that none 
of this would apply to something made within Canada or the US being imported 
for a museum.

 Or "jumper" would do too, ;) avoiding DEC documentation peculiarities

 Not everything has been properly documented, I've gathered information 
from various sources, including reverse engineering.  The bigmax IOASIC 
IRQ bit is I recall only mentioned in an Ultrix error log processing 
utility, though the jumper itself is I believe mentioned in one of the 
5900 manuals, available online.

 Over the years I've gathered available information in Linux kernel 
headers; for the KN03 mainboard specifically:



Interpreted along with:



and knowing that in the console you need to use the MIPS KSEG1 uncached 
address space you get:

KSEG1 | (KN03_SLOT_BASE + IOASIC_IOCTL + IO_REG_SIR)

which expands to:

0xa000 | (0x1f80 + 1 * 0x0004 + 0x110) => 0xbf840110

so to get at the interesting bits:

>>e -wx 0xbf840110
bf840110: 0x8802
>>

i.e. the bigmax bit is set as for the 5000/240 (jumper present), the NVR 
clear bit is clear (jumper absent), and the NRMOD bit is clear (jumper 
absent).  There is also a TURBOchannel slot #0 option interrupt pending 
here for some reason and the halt button is released.

 Always worth doing of course, although from its arrangement the H7878 
would be a pain do disassemble to reach some of its caps.  Also check for 
the PSU overheating condition, reported at bit #4 in the IOASIC interrupt 
status as examined above (with good status indicated with the bit clear).  
It may cause the PSU to eventually shut itself down.

I think the ebay fees for the listing are higher for those features.  
I've seen a lot of sellers listing it w/o reserve, which Ebay pushed 
some time ago.  A simple for sale listing can be inserted indefinitely 
for no fee, for instance.


I don't know if the $1000 price is free to list though.

I would list it at $1000 and OBO, but have not looked up to see if that

Not likely to sell via this treatment of potential buyers.  It isn't

They canceled my order as well, just after sending me a message wondering if I 
wanted the keyboard

I hope they just relist it

On the other hand, this isn't the same as your unit, the connectors on the back 
are in a different
place and I don't see the 9 pin keyboard connector so this may be a completely 
different design

I'm sort of annoyed because I bought a UTS 30 keyboard from someone else. It is 
a Keytronics inside, so
at least I'll dump the firmware in it.

For what it's worth, I've been seeing sellers cancel orders after the fact a

annoying if it is one piece of something that I had to buy parts from other

That sounds like a problem.  If it's not strapped down, it is unlikely to stay

Standard shipping straps may be hard to find for an amateur, but small truck

I've had a few things shipped lately and $250 isn't out of line. It's small
enough that you could try your luck on UShip; if you go that route the

Harbor Freight to strap it to the pallet. -C
