Color Computer 2: White, 4K-64K
One is definatly a coco2 with 64k. no question.
Color Computer 3: White, 64K-128K
I suspect the board I have is one of these with 128k (four 41464s) and
a lot of the logic is on an ASIC.
I've never heard of a TDP-100. The Color
Computers had ROM BASIC and
TDP is TANDY DATA PRODUCTS when tandy was trying to seperate from the
Radiocrap idea in the early 80s.
TDP-100 It's coco 6809, cart port and configureable for 16 or 64k. This one
has 64k I suspect it's the COCO-1 but case color is white and black and
keyboard is chicklet style. Has all the joystick connectors and the like.
It's design is lots of chips compared to the other two I suspect early
design. Also it's serial number 0000038! It also has lots of mods.
The inboard386/pc and inboard386/at are similar save for one is designed to
replace the 8088 and is 8-bit ISA and the other the 286 with 16bit ISA.
The /PC version has 1mb of ram but with more (4mb) I could use it as a slow
(it's 16mhz) linux box. A schematic of the connector for the ram expansion
would be useful, I can hack my own board. The PC version cannot use the
motherboard ram as far as I can see in the book and even if it could I need
more.

Wasn't that the VideoTex terminal? I'd have to dig through some old
catalogs to be sure, though.

VideoTex, I hadn't heard that term in a while. A while back, I got an
AT&T Sceptre VideoTex terminal and was curious what it was; seemed
appropriate for the collection and the price was right :). Did VideoTex
die, was it a fad, a failed attempt at something, or what?

The TDP-100 was a TRS-80 Color Computer with a different paint job that
could be sold by non-Tandy retailers such as Sears and K-Mart. Nothing
more, nothing less.

The TRS-80 Videotex Terminal was basically a Color Computer that had the
CompuServe Videotex program built into it instead of BASIC and an integral
300 baud modem. Possibly one of the dumbest concepts ever done by Tandy
Corporation and despite being an employee I said so at the time. (The
absolute stupidest move done by the company of course was the complete
disavowal of third party products for so many years).

There was (I think) a thing in a CoCo case that was sold as a videotext
terminal. It had a built-in (300 baud?) modem, and linked to a colour TV.
I've never seen one (it wasn't sold in the UK for obvious reasons), and
have no idea if the circuitry is related to the CoCo or not.

I took a look at the one I have but didn't find any docs (it is the PC
version.) It does have the daughter board though with the maiximum 2 MB
of ram installed using 256-12 chips.
