Looks like that one was a steal.
No drives... Floppy controller clearly untested... No boot
or other floppy disks... The only verification of "works"
is that the lights changed when the seller played with the
switches.

Had I seen it before it sold I would have purchased it in a minute!
And put MPM 1.1 on it. But than again I was into SD Systems back in the days I was made a
bunch of
CPM and MPM boot disks.
I had my MPM system in a Cromemco case and always wanted an IMSI case. My first computer
was a
PDP8e making flipping switches close to my heart :)
If the new owner is here somewhere? I would like to talk with them off line. I have an
SD200 and few SD
spares around here somewhere. If the Caps dont blow, and the disks are still readable, I
have the bios &
xios source for that board set. It has all been in storage for ~20 years.
BTW: SD Systems produced the first Z80 card in the market, It was an IMSAI replacement
with a working
front pannel plug. Some where around my Cave I have a (was) working SD Z80 REV1 card with
a lot of
30ga mods on the back that ran 24/7 for years talking to a Morows M26, console, and 4 user
terminals.
Applications were all written and compiled using BASCOM.
Again I digress, back under my rock :)

I think I've got one of those. 2708 EPROM on board? I made an
adapter to go from the front-panel DIP socket to the molex connector
used by the MITS Altair.
Was it really the first one?

They were called SD Sales at the time they produced the first Z80 kit.
They were real prowd of makeing the first S100 Z80 Card that work and
ran a few adds anounceing it, in Byte & DrDobs that would have been in late 77 early
78.
They then came out with a full line of cards and 2 complete systems in 1979..1980
under the SD Systems name.
They were on the North East side of Dallas TX in late 1979 when I flew out to talk with
them about a
dealorship.
As I recal they got into Loto machines and went out of business, but I may be mistaken.
I did not keep track of them after about 1981..1982.

Oh, I know who they are/were--I bought my board as a kit from them
(from a Byte ad, I seem to recall). Just hadn't realized that they
were supposed to be the first S100 Z80 card. I'm not sure about that
aspect though--when did the TDL ZPU card come along?

Not saying it wasn't worth the money asked. Just pointing out that the
poster who brought it up was not comparing apples-to-apples in regards
to the IMSAI offered on this list.
As a matter of fact, it almost proves the value of the IMSAI offered...
base IMSAI unit, essentially untested
with documents $1100 (ebay price)
add truly tested and working $200 (quite reasonable)
add 2 working 8 inch floppy drives $400 (probably cheap)
add known working boot disks $150 (also reasonable)
add 40+ other known working
application disks $150 (maybe a little expensive)
