The F8 is one I skipped over by choice. I do have basic data on it though. The
8080/8085/z80/z180/z280 and Z800x are machines I'm also familiar with. The only SBC
in the 8080 family is the STP cards from VT100s I have gobs of them and they make handy
little controllers. Other chips level cpus I've played with include the 8008,
8048/8049 family, 8051, DEC T-11, NSC800, NEC D78xx series, many of the 4bit machines
other than intel's.

No, I wanted a 9900 based machine to see what was on the non intel track back then. My
9900, ELF, 6800d1 and SC/MP all came from that effort back then. I've had them since
before 1979.
Whoa! The class I took in microcomputers (two actually) was once a week at 7:00pm. I was
a regular full-time day student at that time. However, the class was
populated with many over 30 types and in one class the Prof. was about 60 and the other
class the Prof was 28!
Interesting group of machines. Did the F8 have an eval kit?, as you mention the Ti-9900,
RCA 1802, Mot 6800, and National's "Scamp". Fairchild's F8 seems to
be the ONLY one you missed barring 6502 and Z-80, which became very popular anyway. I
think I have the spec books for most of the chips you list above.

Did you build it for a class project? Techinco was based out of Columbia, MD.

As I mentioned, I was an impoverished student in that time
frame. Nevertheless, I spent a small fortune on books on these kinds of
processors, and computers and programming languages and such. (Not to
mention SF, hot rod periodicals, underground comix, National Lampoon, and
girlie mags). I gave away some of the hot rod stuff to a friend who was
restoring an old Fairlane, but I still have the rest of it. Well some of
the girlie mags are hors de combat, lost in a skirmish with Mothers of
America militia patrol.
Wish now I had spent a lot more on actual hardware, though. I envy
your collection.

Interesting regarding chips and SBCs. Who collects them, other than Allison? I got the
regular run-of-the-mill stuff, 8088, 286, 386, 486, 68Ks -most (no 68060, tho). I do have
a 186, not really rare but seemed to be skipped over like the 68010 (don't have one,
either). Can't say I really have a scare microprocessor. I did manage to get the Mot
88K chipset of all things.
I have a few SBCs, mostly plug-in cards into ISA bus. Some interesting ones. In fact, most
of the lose
chips I have from list above I also have as a plug-in card. I'll have to catergorize
them better and complete generate a list.

I can't say I collect chips, they just accumulate.
I feel better if I give them a good home. A board or system to live
in. :-)

My SBC list - Quest Elf, COSMAC VIP, Z-80 "starter kit", Motorola 4MHz 68000
evaluation board, SYM-1, AIM-65, BASIC Stamp I (14-pin SIP module).
My SBC shopping list - KIM-1 (with working keyboard, natch' :-), Elf-II,
IM6100-based board (Intercept?), Motorola 68330 evaluation board.
I have the article from 1978 where the Elf-II is written up
(http://penguincentral.com/retrocompuing/ElfII/). I've just re-done the
text at the end and am preparing to scan in the missing figures. Some of
that is the actual artwork for the Elf-II PCB. I know I can buy iron-on
transfer paper, but I've never made a double-sided PCB at home, only
single-sided (and then, only with rub-on transfers). Has anyone out there
ever made double-sided boards at home? I'd feel better if I had a layout
package and made my own files so that they'd be nice and square, as opposed
to a scan from a 23-year-old magazine, digitized and laser printed, but I
haven't found a layout package yet that I could manage to start from schematic
and end up with something printable. Suggestions there would be nice, too.

I have a board by DSI that is a 68020/68882 ISA board
that basically runs on
a PC.
I believe mine is by DSI as well, though I'd have to check.
A few years ago I asked about it on this list and was pointed towards
it being a cross-development board of some sort. Unfortunately, I
don't have any of the software or manuals for it.
Is the Apple Z-80 coprocessor boards the so-called
"CP/M boards"?
That's exactly what they are, including the MS Softcard III
for the Apple III. They aren't the same though, which is why they
were mentioned with the 'but' tacked on.
