Can't slip anything past you, can I ... ;-)

If you're going to use the ZIF intermediate socket then you'll have to use a 
cover with a cutout as shown in the DVI manual P.9, or no cover at all.

But if you're not going to use the ZIF socket (since you'll be (un)plugging at 
the other end), then there's enough clearance to use the normal cover as shown 
below; there is a corresponding recess in the case bottom for the cable.

I suspect that was the original idea until folks started to break pins on the 
DIP connector, and they supplied the ZIF socket and notched cover as the 
solution.

I second DOSBox.  I use it not only for games and fun, but for running
ancient software to talk to an old Nicolet oscilloscope (and formerly an
old Tektronix) that I have, as well as old Fluke gear.  It doesn't have
parallel port support (RIP my Andromeda Labs EPROM machine), sadly. But the
serial code is top notch if you want to use an old DOS-based utility to
talk to something over serial.  Like a Model 100...

Re: [M100] List of wanna haves

[Brian White]

It's perfectly interesting and valid as far as I'm concerned.

The only part that's annoying is that you seem to want it to work by magic
or something. You seem to hope that someone else will sit down and slog
through the long and difficult job of figuring out something complicated so
that you don't have to.

If you had actually read the available docs, and started to try to write
something, and hit some problem, I think you would find at least a few
people helping you past specific problems. But when you ask a question, are
given the answer, and say "I can't even read that." Then what else do you
expect? If you can't be bothered to work on your own idea, then why the
heck should anyone else?

I don't know how to write machine code for a m100 either, but from that
reference I at least have an idea where to start, because ai simply
bothered to read it.

If it were my project I know that the first thing I would do is learn how
to write, compile, install, and execute machine code at all. By now I
assume that there are lots of docs available about how to do that. I'd find
an example "hello world" assembly code, and find the tools and steps
required to compile, install, and run that example app. Then I'd build from
there, treating that working empty program as a stub or starting point,
perhaps next adding code to write it's own address to the special address
from the reference, to see if opening CRT: invokes my new stub routine, and
continuing to build from there.

But it's not my idea or project, it's yours. So go ahead. No one is
stopping you.

Anyway, forget it, forget I asked. I have gotten the impression that by
asking something that doesn't sound useful for the technical guys, I have
irritated those people.

Sorry guys, I won't do it again. Just drop it.

I was not thinking of PI, built way too many projects on that platform and 
would prefer another non RTOS  option :) So removable SD card would be a fine.

The powering would be optional either bus or USB.

I fixed the Model M100 problem by using a ZIF socket in the IC socket.  This I 
think was the original way the DVI was sold at least based on my review of the 
docs for the DVI.  But yes that is a pain.

I use my LPT port for an OPL2 card and not sure I want to reuse the port.

I actually disagree with a couple of these, especially if the solution involves 
a RaspPi

   * SD Card ... this would only sort-of be like TPDD2.  The SD card isn't 
really removeable when Linux is booted because it contains the Linux filesystem.

   * Model T Powered  ... again, not so much.  It should have it's own 120 
power connection
   * System Bus Port.  The system bus connection a different form factor for 
the different models, and the M100 has a fragile DIP connector.  My design for 
TDock used / uses the LPT port (and then provides a replacement "pass-thru" LPT 
port on the TDock PCB to connect a real printer).

That is all already written right in the reference I linked you to. If you

in English not Swahili. It explains exactly every step of the answer the
question you *just* posed about how the FC error actually happens, in
detail.

And yes you were shown "what it would take to make it happen", in that it
explains the device driver hooks in the rom.

That is your necessary starting point. Invent whatever kind of
communication protocol you want, and write device emulator code on the pi
and device driver code on the m100 to implement that protocol, and the
reference shows the secret of how to get the rom to use it.

Re: [M100] List of wanna haves

[Ken Pettit]

I actually disagree with a couple of these, especially if the solution 
involves a RaspPi


   * SD Card ... this would only sort-of be like TPDD2.  The SD card 
isn't really removeable when Linux is booted because it contains the 
Linux filesystem.


   * Model T Powered  ... again, not so much.  It should have it's own 
120 power connection
   * System Bus Port.  The system bus connection a different form 
factor for the different models, and the M100 has a fragile DIP 
connector.  My design for TDock used / uses the LPT port (and then 
provides a replacement "pass-thru" LPT port on the TDock PCB to connect 
a real printer).

Hi Mike,

Actually, adding graphics would have to be done via some method other 
than PSET / PRESET.  These ROM  functions work directly with the LCD 
drivers and don't even go through RST hooks to intercept. So they can 
ONLY output to the internal LCD.  Adding any type of graphics to a 
modern DVI solution would involve creating a whole new API / function 
call interface.


My original idea for adding graphics to TDock was to add the capability 
to AsciiPixels.

Although I'm pretty sure that the answer is as Brian posted, I did 
(and still do) want to do some testing  on a real DVI as you asked 
instead of making an assumption; I thought about the same thing quite 
a few years ago and did some investigating, even disassembling parts 
of the Disk BASIC overlay, but unfortunately can't find my notes from 
that time.
Unfortunately I didn't realize that this was an urgent issue requiring 
immediate action and thought it could wait until I could find some 
time to dig the DVI out of storage, find a monitor, hook up an 
LA, etc. etc.
Sorry you couldn't wait; that's the trouble with asking hobbyists to 
do something for you...
I understand that you want a solution that connects through the system 
bus and emulates DVI video exactly; I just wanted to display the 
M100's screen across the room on a 40" TV while comfortably reposing 
an the couch playing games, so I chose the easy way using the serial port.
I thought maybe this would be interesting while waiting for Ken's 
complete solution (especially since using the com port allows a 
wireless Bluetooth connection), but apparently not, so I was curious 
what you and others wanted to do that this didn't satisfy.
As John pointed out it does tie up the serial port, but it seems that 
you might also be able to use the same connection with TS-DOS or similar.
BTW, there's also an article in Portable100 about using the parallel 
port, but although I happen to have the exact obsolete hardware used 
it looked a lot more complicated and limiting.
I'm not sure where you're getting '40 x 16' video as in your other 
post; AFAIR it's either the normal 8 x 40 or 24/25 x 80.
One other thing: the DVI is text only; if you're going to the trouble 
(as Ken probably will) then you might want to also add graphics (even 
if only the PSET etc. functions) and maybe even colour, which will 
obviously complicate the situation somewhat.

What's so interesting abou an external screen ? I can hook up a

one around. It is just another thing that makes working on you
computers a bit more comfortable when you're not on the move. You

The DVI is the old-school equivalent of a docking station or a
port-replicator. Why would it be useless to re-create that with
modern technology, certainly now that 'its so cheap?

Anyway, forget it, forget I asked. I have gotten the impression
that by asking something that doesn't sound useful for the

Which I think is why when we’ve talked about this before the

Has anyone dis-assembled the DVI disk basic previously?  The DVI boot disk 
contents are available and interesting.  Or recommend an 8085 or Z80 
dis-assembler?

The DVI uses a Z80 clone so some of the boot disk is Z80 DOS code.   It was 
quite a clever design for its day very flexible should Tandy of wished to have 
continued development.

Does it jump to FC Error directly, or because it checks that there is nothing 
hanging on the system bus? That could be determined by looking at the ROM-code. 
But again, AFAIK, nobody checked that. (at least, nobody posted it)

So, you probably need software to prevent the FC error, just like the driver 
from the DVI. Would that be difficult to write? Hasn't anybody dis-assembled 
the code for the DVI? You'd only need the video-portion.

Hi Jan,

I for one am not irritated :)  Actually, you made me think about pulling 
out the TDock PCB I had assembled for this very purpose and just getting 
the thing to work finally!  I keep hoping the day will come when I have 
time for fun projects like this again.

I'm quite interested in what amounts to a M102 docking station. Not that it

Sure. And meanwhile, I understood why not. But not thanks to the replies I got

Does it jump to FC Error directly, or because it checks that there is nothing 
hanging on the system bus? That could be determined by looking at the ROM-code. 
But again, AFAIK, nobody checked that. (at least, nobody posted it)

So, you probably need software to prevent the FC error, just like the driver 
from the DVI. Would that be difficult to write? Hasn't anybody dis-assembled 
the code for the DVI? You'd only need the video-portion.

I hope that the response given in the above thread helps and incites people,

to pick up on this project and propose the parameters for a video-interface.

As far as I understand, the driver loaded from the DVI re-maps the video 
controller of the M100 towards the one in the DVI, where new tekst and graphics 
are generated. The 4K memory in the schematics is obviously the video-RAM, 
where 40x16 text (640 bytes) and 240x128 points  (3840 bytes) reside. I suppose 
text and graphics do not reside in different memory locations. (because it 
doesn't fit...)

Anyway, contrary to what I thought before, we will probably need to activate 
the SCREEN 1, 1 directive with software on the M100 itself. But that software 
does not need to be as big as the original driver, because no disk-routines are 
necessary.

I'm sorry if I sound presumptuous, and I apologise if I impose on people's

Like I said, I wanted a Raspberry Pi to emulate a DVI. The DVI uses the system 
bus. I never spoke about the COM-port.
I'm sorry, I wanted to say the 40x16 video output. Again, just like the DVI.

I have a question, for anybody having a DVI:

Could you try the following: is it possible to operate a Model T hooked up
to a DVI, with the DVI ready to accept input and disk commands, but the
Model T without the driver software? I would think this is possible when
you boot up both machines, establish the connection, and then, while
connected, reset the Model so that it is no longer aware of it's
'companion'. At that moment, enter BASIC and type SCREEN 1,1. That would
send all BASIC output to the DVI, right? Does it ? (thàt's the question)



The above experiment would show if it's at all possible to run a
monitor-only part of a DVI, without loading software on the Model T to do
so. I hope, that the simple command SCREEN 1,1 does send some

  I hope that the response given in the above thread helps and incites people, 
with far better and more knowledge of the processes and controllers involved, 
to pick up on this project and propose the parameters for a video-interface.

   

  As far as I understand, the driver loaded from the DVI re-maps the video 
controller of the M100 towards the one in the DVI, where new tekst and graphics 
are generated. The 4K memory in the schematics is obviously the video-RAM, 
where 40x16 text (640 bytes) and 240x128 points  (3840 bytes) reside. I suppose 
text and graphics do not reside in different memory locations. (because it 
doesn't fit...) 

   

  Anyway, contrary to what I thought before, we will probably need to activate 
the SCREEN 1, 1 directive with software on the M100 itself. But that software 
does not need to be as big as the original driver, because no disk-routines are 
necessary.

   

  I'm sorry if I sound presumptuous, and I apologise if I impose on people's 
limited time, but I think this is a project worth pursuing.

  That won't work. I don't remember where I read this, but I read that the 
system rom has calls for certain functions but they are just stubs. The rom 
only contains the stub of a call that says "open CRT: for writing" which just 
says go to some address and do whatever that address says. Normally that 
address just points to the address for the built-in routine to return the FC? 
error. But if dvi dos is installed then that address contains the address of 
the routine in dvi dos to actually do something.

I'm not aware of any software that uses the 80x25 screen mode, and redirecting 
the 8x40 display through the com port to a Pi or laptop etc. is trivial, so 
what makes this worth while (other than the challenge/fun) ?

both machines, establish the connection, and then, while connected, reset the 
Model so that it is no longer aware of it's 'companion'. At that moment, enter 
BASIC and type SCREEN 1,1. That would send all BASIC output to the DVI, right? 
Does it ? (thàt's the question)

The above experiment would show if it's at all possible to run a monitor-only 
part of a DVI, without loading software on the Model T to do so. I hope, that 
the simple command SCREEN 1,1 does send some screen-positioning code through 
the bus towards the DVI, even without the drivers loaded on the Model T.  If it 
does, some clever programming on the receiving side could just give us the 
DVI/video-only device we seek.

That won't work. I don't remember where I read this, but I read that the
system rom has calls for certain functions but they are just stubs. The rom
only contains the stub of a call that says "open CRT: for writing" which
just says go to some address and do whatever that address says. Normally
that address just points to the address for the built-in routine to return
the FC? error. But if dvi dos is installed then that address contains the
address of the routine in dvi dos to actually do something.

Aha, here's where I read it. Start on page 257

I can try it when I get home but we already know.

Nothing like having the modern platform itself also go obsolete. I guess
it's happened a few times over by now. There's plenty of "bridge to the
present" things which themselves run in MS-DOS.

If you have an android phone, try mComm for Android. That's the closest you 
will get to the NADSBOX. It emulates your standard TPDD and adds the Sardine 
Spell Check as well as a virtual modem mode for 'dialing' Telnet BBS sites. The 
virtual modem handles the flow control issues that are inherent to the Model-T 
when using TELCOM.

Yes looks like they did, I think it is really for Arduino boards or that type 
of board. Those boards all use TTL level serial outputs or I guess 3.3V these 
days :) Showing my age….

I think all the serial-to-VGA boards out there use TTL levels.

A serial to VGA board.  I recall there is also some software to redirect the

serial-to-TTL level shifter.
