Hi
Still can't imagine a SYM-1 being worth $900. From $75 to maybe
$150 someplace is more like it. It has little to be note worthy
of that I know of. The KIM is more recognized as a historic
board. I doubt if that person though it was actually worth something
that they'd have thrown it away, regardless of what they said.
Still, for one rounding out their 6502 collection, the SYM-1
is a nice item to have.

Speaking of which, iirc someone offered me a
SYM-1 a while back.. they
wanted somewhere in the region of $900 for it. Last I heard, it hit the
dumpster. Real shame - then again, their property, their choice :-/
This just twists my brain.
"I think this computer is worth ONE MILLLLLION DOLLARS. What, you'll
give me 20 bucks? Instead of taking your twenty bucks or putting it up
for no-reserve auction, I'll just throw this million-dollar computer
away!!! MuaHaHaHaaaa!!!"
Been there, did that, still bitter.

Aside from being a "better KIM"? ISTR it was basically a KIM with a few
extras (oscilloscope output, a la the Poptronics Scopewriter) added. I don't
think it used the mask-programmed RIOT chips either, unlike the KIM, which
makes it (slightly) easier to fix if something goes wrong.
I'd be tempted to add a bus-buffer board between the SBC and any off-board
hardware. I'd rather blow up a handful of 74LS244s than a pair of 6532s (or,
worse, an entire board).

I agree. I've got a homebrew 6502 computer here - a backplane, a CPU card, an
RS232 interface card... and an SP0256 speech synthesizer. That was fun to
play with :)
Only problem is, with the backplane filled, the timing got screwed up pretty
badly. At 2MHz it's fine, but if you go above that, it fails to boot ("03 RAM
CHECK"). I think I need to rebuild the backplane and add some bus-buffer
chips this time...
Later.

It does not use mask-programmed RIOT chips... one of the reasons I'm happy
to have a SYM-1 - no unobtanium ingredients.
