The Color Computers were:
Color Computer 1: Silver/black, 4K-64K
Color Computer 2: White, 4K-64K
Color Computer 3: White, 64K-128K
Micro Color Computer: White, tiny, 4K
I've never heard of a TDP-100. The Color Computers had ROM BASIC and
most serious users ran an operating system called OS-9 which was kind of
like TopView.
Expansion is via the cartridge slot. The floppy disk interface was
implemented as a cartridge, with the floppy OS in ROM in the controller
cartridge. CoCo floppy drives are rare. Floppies stored 156K. There
was also a hard disk cartridge, believe it or not; plus, a Multi-Pak
Interface which allowed you to connect four different carts and switch
between them.
There are lots of CoCo fanatics around, somebody probably sells parts
and maybe even schematics.
In regard to the Inboard/386, as I recall it had 1MB 32-bit RAM on the
card, and could optionally use motherboard RAM which of course ran at a
much slower rate. My memories may be confused with the Inboard/386 AT,
but I seem to remember a daughtercard which could store an additional
2MB or so. Good luck finding a daughtercard though.

Subject: cocos and stuff
HI,
In my non-op list of equipment I have three cocos apparently
operational.
They are of two different styles.
The smaller is the TRS80 color computer with real keys on the
keyboard.
I have two of these one the case was wiped out, board is ok.
The larger is TDP-100 personal color computer with chiclet keys.
Lacking docs I presume these have rom Basic. What expansion is
possible
(there is a port) and how hard. Do they run any real OSs or some
TRShack?
What's the odds of finding DOCS especially schematics?
I have a xt class machine with an Intel Inboard386...(works too!)
what's the
odds of finding schemtics or expansion ram for it? The 1meg of ram is
tight
for somne stuff. Currently I use it as a 10x faster xt.

I have a CoCo2 that's yellow, and I don't think it's from aging.

Mine is slightly yellow. I have a CoCo II, with 64k and 2 disk drives (One
has failed, though) and the BASIC book that came with it (Minus the cover).
It made it through a house fire, I suspect that may have accellerated the
yellowing. That was my first computer, it now lives under my PDP-11/23.
I also have a TRS-80 Model 100, it is currently the terminal to the 11,
and it needs a new keyboard (4 keys have quit working, I can't seem to
get them working again). I still have the tape I saved all my basic
programs on. I never did learn assembly for it. Somewhere I have the
thin book with the system specs on it. I lost the cassette recorder
somewhere, but I still have the cable, so I can read the tape.
I fire it up when I get time, just to run it some.

You mean 128K-512K, I think. The CoCo 3 needed 16 bit wide RAM for the
video system, and used either 4 off 64K*4 chips on the main board, or a
daughterboard with 16 off 256K * 1 chips on it. Some hackers went up to 2M
I think

like TopView.
OS-9 is actually a lot more like Unix (at least to a user). There was a
graphical frontend called 'Multiview' (or some similar spelling) for OS-9
level 2, but you need a CoCo 3 and 512K to run that.
