[GreenKeys] S-100 computer interest of late

[Ralph Irish]

​Just wondering if there might be a GreenKeyer interested in an IMSAI computer? With all of 
the recent mentions of newer plug-in boards for this family, maybe someone might want to try 
this 'vintage' system? 

I built one back when the IMSAI was quite new but never did anything with it. I took it to the 
home of a friend who finished his IMSAI and tried his Processor Board in my computer, and my 
Processor Board in his computer and everything worked. So, I got those 2200 solder joints done 
properly on the 22 slot Motherboard board, as well as the front panel board. 

I have a number of other boards that were started and some finished, but never actually put to 
use. Several memory boards, a MIO (I/O) board, a music board, and a flock of cables and other 
'parts' that have lived in the boxes associated with the computer. 

It is way too heavy and clumsy to ship, so I would like to find someone local, or someone within 
driving distance, or perhaps 'driving-meeting' distance where we both aim toward each other 
and find a stopping place, etc. 

This is more of a 'space making' venture as opposed to a fundraising venture. Not to say that I 
will give it away, or anything, but I'm hoping that after seeing the full inventory of what I have, 
I can get a reasonable offer for the package. 

One item that I mentioned several years back is a 'fanfold' stack of gray 1" perf tape with 
SOMETHING punched into it. I don't know what it is part of. I had hoped to find someone willing 
to run it through their 33ASR and supply a printout of what it shows. Didn't get any takers on that. 
It might be a version of "Tiny Basic" but that is just a guess here. 

I got a 'hand-me-down' Apple ][ Computer from a friend who moved up to a ][ Plus or 2E, and sort 
of stayed behind him as we moved into the Mac World. I still have his original 'Test Drive' Mac and 
the Macintosh carrying case and floppy drives, etc. But, that's another story. 

Anyone interested please get in touch off-list and I will go through the items and make an inventory 
for their perusal. There is probably enough there for someone to 'finish' a nice working machine, or 
have the DeLuxe computer box with the largest Power Supply that IMSAI sold at that time. (30 amp? 
Large, heavy transformer, large heavy choke, large 'computer grade' filter caps and large rectifiers.) 
I think that the unregulated voltages were + and - 8 volts and + and - 18 volts, to be individually 
regulated on each plug-in card, to + and - 5 volts and + and - 12 volts as needed. 

It could be a nice addition to a 'vintage computer/Communications' display or just a nice, dated 
machine to have working in your location.
