One correction.
Step One.  Tell wife you will be using the dining room table for the next 7 
months to display your new vintage computer system!  "Isn't it amazing and

I tell my wife where all my toys are and that they are worth money if I go.

never traced this code out in the NEC system ROM disassembly, but now I'm

Kurt,

The system disk must be in the drive at the time when you reset the NEC.

Sequence is this:
1. Insert the system disk into the drive
2. Make sure the PC-8231A is connected to the SIO1 port (RJ-45 jack) on the
back of the NEC
3. Power on the PC-8231A
4. On the NEC, either Either powering off and on, or hit the reset button,
or perform a full cold start
5. The drive light comes on and "DISK Basic 2.0" gets loaded in a couple of
seconds.

Perform these steps without the system disk in the drive and instead the
drive light just comes on and the NEC hangs and has to be reset, so it is
definitely reading the code from disk.

So there must be system BIOS code on both the 8201 and 8300 system ROMs
that does some type of initialization sequence with the SIO1 port and spits
out some command sequence and starts reading bytes after you do a system a
reset.  I've never traced this code out in the NEC system ROM disassembly,
but now I'm curious..

Well, there are SPI BT/BLE modules so speed to the ModelT side shouldn't be too 
bad, either using the bus or the parallel port...

Alternatively, there are modules like this (VGA colour display and 
FAT-compatible SD card storage):

Of course before long you'd have lots of stuff hanging off the ModelT again...

I hadn't even considered using a TPDD server (Android, WIndows, whatever) for 
such a purpose. I suppose it's possible to create a window that displays data 
sent over the serial port in a new display packet format. Though it would 
likely be slow and limited to text only.
The system bus or parallel port would be MUCH faster for this. I think Ken was 
working on something that attached to the parallel port not too long ago.

 I personally value not dragging another power supply around.  Something 
designed to fit inside the power capability of the M100 - hence taking power 
from the system bus - is more appealing for me personally.

As hardware is often a stumbling stone, would it not be easier to use a
RaspberryPi-like or other sbc to act as a DVI ? Or an Arduino-like
controller? In that case, development would be limited to software and some
hardware connections. It's a single task this hardware has to perform, so

[Stephen Adolph]

The video adapter for the 8201 is superior to the dvi.  it has color, and
it runs of the m100 power supply.

[VANDEN BOSSCHE JAN]

You mean : Color ? ;-)

My 2 cents: (About rebuilding a (D)VI)

As hardware is often a stumbling stone, would it not be easier to use a 
RaspberryPi-like or other sbc to act as a DVI ? Or an Arduino-like controller? 
In that case, development would be limited to software and some hardware 
connections. It's a single task this hardware has to perform, so it doesn't 
have to be powerful. Furthermore, it could be more flexible and adaptable to 
both Nec and Model T.

Because if you start to develop everything from scratch, it might turn out to 
be a very lengthy process...

yes, possibly.  the VI portion of the DVI is all you'd want, and it is
based on a Z80.   good point.  I guess both have a composite output
signal.

 "reverse engineering that device would be useful.  I think it would even be

The schematic for the m100's version, the Disk Video Interface, is available. 
Would it not be possible to make just the CRT adapter from that schematic?

Is the NEC disk unit similar to the TPDD as far as command set goes? I guess 
another way of asking that is whether or not TS-DOS will talk to it. I know the 
NEC has a higher capacity per disk but I wasn't sure if there were more 
differences.

Just to let you all know, I did win the auction.   I do intend, however, to
try to resolve the issues with my other NEC CRT adapter if I can.  If I can
do so, I certainly would like to make that one available to someone here.
I don't want to hoard NEC CRT adapters!  :)

In fact we may want to even try to figure how to replicate it. It's a
simple board inside the thing with what I believe is fairly simple parts..
  I *think* the biggest challenge would be replicating any PROMs that are
on it and then trying to find a source for the bus connector itself.

Displaying M10x video on a big screen is no problem if you don't mind giving up 
the RS-232 port; there are lots of display/terminal modules out there and it's 
trivial to redirect the LCD text (no graphics of course). Shouldn't be a big 
deal to hook into the system bus; I think it's been discussed but never got 
very far...

I've used a Bluetooth link to an old laptop; neat to lie on the couch playing, 
programming or puzzle-solving on the big screen across the room.

But what would really be nice is having the 24 x 80 display mode; the DVI's 
BASIC extension does this and I tried to figure out where and how it's done but 
never did get very far.

Re: [M100] NEC 8201A + NEC 8231A + NEC 8241A=WOW

Yes it's on eBay right now. The price is already quite high. Search for the NEC 
and it will come up.
The CRT unit is really the key item. Although the drive is intriguing to me. I 
have been tempted to try and emulate it with mComm but I suspect there are two 
things that I would run into.1) I suspect there is a special boot disk that has 
the code that gets loaded.
2) Not having a drive unit, it would likely be impossible to reverse engineer 
how the NEC and the drive communicate on boot up.3) Even if items 1 and 2 could 
be solved, TS-DOS in ROM kind of makes it pointless. 

About the only advantage would be to have the drive connected to the RJ45 port 
and still have the serial port for other activities. I'm not sure how that 
would work out if there were two connections at the same time since there is 
really only 1 serial port that can switch between three ports on the back.

 Is this an auction? I'm missing the link to whatever it is that's being talked

I've had my eye out for the CRT adapter for a long time. But with three kids in 
college, the funds are being used elsewhere. Hope you are able to get it.
The Disk drive is interesting. As I have read, the NEC units test to see if the 
drive is attached on boot and if it is, they load the extended basic. Has 
anyone ever documented this process or captured the extended disk basic?

 Thanks for the head's up, Kurt.  My CRT adapter has become defective and I 
don't know how to repair it; I will hopefully get a functional replacement
