Re: [M100] Cassette-emulator ?

[Steven Ranft]

Has anyone tried using a Digital Voice Recorder?
The advantage of using the Cassette (audio) interface is that the format is 
understood by many M100 type systems and no software or drivers are needed.  
The drawback is, it's slow.
I think I will try using a Digital Voice Recorder for storing and retrieving 
the next time I have my M100 set-up.  If it works, it will still be as slow as 
a cassette tape drive. But naming the programs and finding the start of them on 
a Digital Voice Recorder is much easier than on tape.  Also, the digital voice 
files can be backed up to a computer much more easily than tape backups.


Thank you,



Steve

I set out to do this with an Arduino some years ago and built the hardware on a 
breadboard. I never got past decoding the FSK signal from my M102 though and 
gave up for whatever reason. I think I ordered a REX. 

The idea was to store the decoded bits in a 1MB EEPROM connected to the 
Arduino's SPI interface.

Digital/decoded storage would be the way to go.

The cassette file byte format is understood.

It could be done in a smart phone app or embedded device.

I replaced one of mine with a NiCad a while back, but I don't think the slow

It took over 30 years to get to the state it is in now... So in the year 2048 
it should be about the same, if you put a good new battery in...

But it could save a very rare (especially by then) piece of hardware some 
serious damage.

If it is going to be open anyhow, I would spend the extra 10 minutes.

I like this advice.  Having recently realized that the NiCD batteries I ordered 
ended up being NiMH, I'm also pretty dubious about their quality.  I'm sure 
it'll be fine for years to come but probably not as long as the original which 
was still kicking and only just showing the barest signs of leakage, not even 
to the motherboard yet.  It actually makes me think that I should proactively 
assume the next owner will come across this little computer potentially long 
after I'm gone and it will have been in a box somewhere for years.  I wonder if 
it might help to put a small square of thin plastic , followed by a small 
square of some absorbent material like cardboard or paper, between the battery 
and the motherboard with two tiny slits for the battery terminals.  This might 
keep the leakage from doing any real damage somewhere down the line.

I'm sure this is overthinking the problem (perhaps Scotch induced) but I like 
the idea of designing a solution that takes into account the inevitable failure 
somewhere down the line.

Hi Steve,
 
Where to begin...
 
First of all, you're talking about two different 
and separate ROMs and their sockets, the System ROM which runs the computer 
and provides the various built-in applications, and an Option ROM which, as the 
name suggests, adds one or more optional programs or features. They are both 
28-pin 32KB (256Kb) chips, so your 32-pin 128KB 27C010 chips will not fit 
without major adaptation.
 
As you (re)discovered regarding North American 
models, early M100s (prior to late 1983) used a non-standard pinout while later 
M100s and the T102, T200 etc. used standard 27C256-compatible ROMs; the change 
seems to have been made somewhere between serial numbers 309xx and 
401xx.
 
If you want to replace an early M100 System ROM you 
will have to make or buy an adapter; a fellow list member just built some using 
this board:
https://www.oshpark.com/shared_projects/Kil9S1ya
Replacing a later model M100 System ROM is just a 
matter of plugging it in, but in the T102 it is soldered to the board and would 
require unsoldering the original ROM.
 
The Option ROMs use a completely different socket 
arrangement, a Molex IC 'carrier' with non-standard pinout but you can use 
the adapter above which lets you combine the System and Option ROM in one chip 
that plugs into the System ROM socket (old or new). At one time there was an 
adapter available from several sources that would let you put an OTP (not 
re-programmable) EPROM into the option ROM socket but they seem to not be 
available any longer.
 
Most people use Steve Adolph's REX module, which 
lets you put several different ROM images into one flash memory and I believe 
the later versions also permit changing the System ROM; see:
http://bitchin100.com/wiki/index.php?title=Rex
 
Another very useful add-on is/was the NADSbox but I 
believe they're no longer available unless you find a used one; a newer version 
may or may not become available in the future.
 
Can't really give you a step-by-step since I 
don't know exactly what you want to do with/to what.
 
Good luck!

Hi Ken,I saw the Raspberry Pi A is for sale for $20 
now!https://www.raspberrypi.org/blog/raspberry-pi-model-a-plus-on-sale/
I have an idea that would be easy, if I could write code I would write a TPDD 
emulator for the Pi. 
Perhaps the Pi can handle a copy of LAPDOS in DOSBox running on the PI, but I 
think I would need a keyboard and monitor to get that up and running.
The more elegant solution would be to configure the Pi software to do the 
following...
I think it would be great if the Pi could be set to self boot to boot a TPDD 
emulator, and write the files to a USB thumb drive plugged int the PI, in a 
format that could be read on any computer.  There would need to be an easy way 
to initiate a shutdown of the Pi, without need for a keyboard or monitor.There 
are GPIO pins on the Pi for serial connections, and drivers for Comm ports 
ready to download.I could build a cable that connects from the Model T to the 
GPIO connector of the Pi, and also connect a switch to alert the software to 
shut down when the switch is held down for more than 2 seconds.The Raspberry Pi 
would not even need to be dedicated to the role as a TPDD emulator. Remove the 
cable and the SD card and the Pi could be used for any other function desired. 
I could try to figure out how to do this on my own but I am guessing someone in 
this group knows enough about Debian and DosBox and LAPDOS to know how to do it 
without breaking a sweat...
Any takers?

Hi Lee,



Well, no that isn't exactly wrong.  The 8-bit output port on the
M100 LPT connector is in fact output only.  However it has 2 input
bits ... the BUSY and /BUSY signals.  With proper 8085 ASM software
and proper ARM software, a 2-bit "bit-bang" read operation can be
performed.  In this case, 8 bits are read using 4 successive reads
of { BUSY, /BUSY } and then re-assembling them into a byte. 



This is the way TDock works and I have actually already written and
tested this approach in VirtualT.  I actually have 3 TDock bare PCBs
sitting on my desk that I received from OSH Park yesterday, waiting
to be assembled.  They use a CPLD to perform the signalling and the
board is a daughter card for the Raspberry Pi 2 B.  But I'm afraid
the solution isn't really "cheap" because of all the connectors and
the size of the PCB (building the TDock PCB costs more than the Pi
itself because of small quantity purchase).  But I believe a fast
STM32 ARM chip with 5V tolerant I/O could keep up with the
signalling involved that the CPLD is doing.

I saw that Uber cheap pi. They don't quote power but
I believe it is vastly more than the M100 itself.

Re: [M100] USB "juice pack"

[Steven Ranft]

I found this on Amazon here in the US. 
http://www.amazon.com/gp/product/B00H01VGTQ?redirect=true_=cm_cr_ryp_prd_ttl_sol_0
It has the same DC to DC converter as the cable John Hogerhuis located in the 
UK.The DC to DC converter boosts the 5V output of the "juice pack" to 6V, which 
is what your Tandy AC adapter outputs.
For only $10 it look like a good deal.
The output plug would need to be changed to suit the M100, but the voltage 
should be fine. 6VDCIf you don't solder, these might work for 
you:http://www.amazon.com/Power-Cable-Female-Connector-Camera/dp/B00EK6OAF6/ref=cm_cd_al_qh_dp_t
 
Unfortunately you would need a meter to be sure how to get the polarity correct 
for the M100.
Obviously, If you can solder and have a meter you can find a plug that would be 
more elegant.

Hi John,
I use a 6v lantern battery in a plastic frame with a power switch and cable 
with the correct barrel connector on it.  I got it while I was living in 
Australia before I moved over to the USA do i don't know what the part number 
is.  I may have even got it at the local tandy store  :-)
Cheers,Bert

Anyone know what it takes to use the phone charger "juice packs" to run a M100?

Is there an off the shelf connector or converter needed or would I
have to build something myself?

I have a handful of vendor swag cheapie units laying around. Running a
Raspberry Pi off one of them.

Re: [M100] Mxxx Software of 3.5

[Steven Ranft]

I second the motion to make Back-up disk images of any vintage software before 
endangering it. I would use a hi-res camera. Scanners ensure perfect lighting 
and focus with almost zero setup time.A good camera will give you similar 
results with a little set-up time.Your cell phone is probably good enough. Turn 
on multiple lights to eliminate shadows. rest the phone on the back of a chair 
near the table to reduce shaking. If the lights are bright enough it won't 
matter. take 4 or 5 shots, and chose the best. Crop it and save it to one of 
the cloud services, to download to your computer without cables.
I do this with Expense account receipts when travelling..

I have a batch of M10x, M200 programs on 3.5 disks. Too 
many to bother listing individually. My question is, what's the consensus for 
just scanning the disks/labels and post the scans. Anyone think stray scanner

Re: [M100] $9 Computer

[Steven Ranft]

Model 2000 ( of the Model T)
You are correct, there is a Tandy 2000, but it's not a TRS-80 Model 2000, and 
not a TPL
I refer to the TPL described by Steve Adolf on Bitchin 100: 
http://bitchin100.com/wiki/index.php?title=True_Portable_Definition
True Portable Definition
The minimal definition for true portable laptop is:Light-weightGeneral 
purposeAt least 15 hours battery life on a charge with normal useInstant or 
near-instant ON/OFFNo heat issuesUI navigation is easy and efficient without 
a mouseThe ideal laptop:Off-the-shelf batteriesEasy access to built-in 
programming languageNo heat issuesFull-travel keyboard
I Think those are the PRIMARY design parameters.Adding a LithiumPolymer 
battery, a mouse pad are EXTRAs.I believe that anything proposed by should be 
able to use off the shelf batteries, for over 16 hours of normal use per set 
(Excluding WiFi, BlueTooth and other power hogging functions)It should boot to 
a MENU driven system that is easy to navigate with the keyboard only. (Mouse 
would be an enhancement, not a requirement)
ALMOST EVERYTHING that has conceptualized my men has been built EVENTUALLY!
Perhaps we need to perfect the CONCEPT. If it is good enough, it WILL get 
built... (eventually)
One last thought. Perhaps CLUB 100s concept should not include a main 
board.Maybe we design a chassis with all our other requirements, and leave a 
spot for anybody to drop in a proto-type main board.  We would just provide a 
platform for others to fill. THAT would be marketable.
AND we could design the default starter main board that is 100% TRS-80 Model 
100 compatible!
Thanks,Steve

I like it: Let's design a Model 2000
I think it should be as high tech as we can make it. It should be ahead of it's 
time Like the first M 100 was and totally customizable and adaptable.
The ROM should be flashable from an SD card. This machine should boot from 
Flash ROM but be bootable from USB, SD, or network. 
Perhaps it should have multiple CPUs to allow native DOS, and modern 64 bit OS 
on the same platform.
Making it Open-source would make it much more attractive to a larger audience.
I don't know if LCD is the way to go. 
The Nook and Kindle e-readers have High resolution paper white display that go 
for days,they also are very readable in all lighting conditions.

1280 x 960 is 4 times the resolution of VGA so it would have excellent DOS 
graphics.  I think a clam-shell design with a 1280 x 960 BW e-reader type 
display would be my choice.
Killer keyboard is a must!
It should have USB 3 and SD slots, 3 AAA batteries NOT AA this is the 21 
century.
Perhaps we could also add a slot for a replaceable Lithium-Polymer flat pack 
like a cell phone. 
The charger circuit should auto detect the AAA batteries and if it senses 
rechargeable, it could trickle charge 3 AAA from a USB charging cable (5 volts) 
with 4 batteries it wouldn't work. 
With AAAs it would be thin enough to resemble a net book. Clam shell would 
protect the screen.
WiFi and Bluetooth are battery killers, and should have an auto off in BIOS to 
turn them off when the unit is unplugged.

I'm coming back to the dream we sometimes share: re-building the Model T with 
current technology.
 
3-D printing gives us the opportunity to (re-)design the case.
 
Cheap computers, like the one below, or a RasPi, could provide the heart. 
Autoboot an emulation! Does VirtualT on Linux exist yet?
 
Apparently, the type of display of the Model T 240x64 is still made.
Eg. from the page 
http://www.alibaba.com/showroom/240x64-graphic-lcd-display-module.html ... take 
your pick!
The following stands out (size, price, colour, ...) 
http://www.alibaba.com/product-detail/monochrome-STN-graphic-240x64-lcd-display_60110813146.html
 
All we need to find is a keyboard. No numpad! and how to connect the arrow-keys 
?
 
And money, of course... Crowdfunding ?
 
Ah, I can dream, can't I ?

 I was thinking of calling it the Model 110. (I suppose it could be 
 called the M150, being halfway between the 100  200...)
 
 My desired specs I've been working toward for a decade...
 
 Same basic dimensions overall as the M100 or M102.
 
 Full-stroke, clicky keyboard, same size as the M100's. NO TRACKPAD OR 
 PALMREST.
 (one thing I hate about modern laptops is that space below the keyboard 
 that holds my hands up)
 
 Wide-aspect display, as close to same dimensions of 100's LCD as 
 possible. As high resolution as possible.  I'd settle for 480 x 128 
 would be okay, because it could give me 80 columns; 720 x 192 would be 
 fine, 960 x 256 would be great.  1350 x 360 or 1920 x 512 would be even 
 better. Black and white or grayscale would be okay, though I wouldn't 
 want E-ink. E-ink is tempting, but the refresh is way too slow, even 
 worse than the M100. I want animation :)
 
 Capacitive touch screen, and/or a trackpad/trackball above keyboard.
 
 128k ram or up. At least 1gb if the OS is a variation of Linux and/or 
 the video ram is shared with main ram.
 
 2D/3D acceleration, even if only as powerful as the late-90s; OpenGL 
 compatibility.
 
 SD for storage; 2 x USB 3.0 for connecting; RS232 for backward 
 compatibility; bluetooth 4.0, 802.11b/g/n wifi for communication
 
 Support for SSD (SATA or IDE)
 
 ROM booting
 
 OS = customized FreeDOS variant, Linux distro, or WinXP. Possibly 
 Symbian. No Android.
 
 Intel or ARM processor.
 
 Able to run on AA batteries or rechargeable.
 
 Stereo audio (out jack, if not speakers, too).
 
 AC97 or Soundblaster compatible audio.
 
 Tiny Camera above screen for video conferencing.
 
 Possibly slight wedge shape to improve typing angle... maybe.
 Built-in lapdesk (padded bottom with cloth or faux leather, detachable).
 
 About all I can think of.
 
 With the dimensions of the M100, there might even be room to squeeze a 
 thermal printer in there.
