I'm in the process of restoring two Altair 8800's :
S/N: 221045A
S/N: 223959K
Both were not working when I got them... most of the work needed was replacing bad logic chips on the front panel and fixing broken traces.
They are finally both working, but neither have a serial card. I would really like to get my hands on an MITS 88-2SIO Serial Input/Output S100 board, but only seems like that will happen if I buy another Altair with one already in it... Does any one have one they would be willing to sell. If I don't get my hands on one soon I will likely CAD up a replica 88-2SIO pcb and source all the chips..
I know Grant Stockly @ altairkit.com was testing an 88-2SIO reproduction PCB back in 2007 but I haven't been able to get ahold of him... Would really like to get my hands on his KiCad PCB drawings...
Here are my two Altair's and my newly restored ADM-3 Terminal:
