Hello all,
I have been intrigued by a couple of eBay auctions:
The first one:
http://www.ebay.com/itm/191765141319?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
The second one:
http://www.ebay.com/itm/252218142611?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
As you can see, these two Altair Turnkey systems have different boards in them:
The first one:
MITS 8800B CPU BD REV 0
ALTAIR 8800B TURNKEY MODULE REV 0
MITS 16K RAM (?)
The second one:
MITS 8800B CPU BD REV 0
PCC TURNKEY MODULE
PCC S-100 INTERFACE
CEPC 4-SIO-1
I can see that the first one has a memory board but no I/O board, and the second one has no memory board but it does have an I/O board. And, of course, the second one has the power switch key, but it is indicated that it is not the proper one for this system.
The bulk of my experience with S-100 systems is with IMSAI systems. Can anyone please tell me what were the original boards that would have been in a stock Altair 8800B Turnkey system? Was it like the original Altair 8800 kit, where you got only the CPU board and the front panel? Would it have been only the CPU board and the Turnkey board? Then the buyer would have had to add memory and I/O?
Is the first one actually incomplete because it does not have the PCC S-100 Interface board? I am not familiar with this board. Is it a required board for the system to run?
Any assistance and/or advice that you may have to offer would be appreciated.
