So far I have de-soldered a bad socket. Most of the components will need to be replaced. More to come.

This is a second MITS Altair 680b 16K RAM card. I took parts from the first card and installed them into this card. I still have the first 16K RAM card to be used for parts.


And here is a view of the ACIA monitor. I ran a few simple memory tests to verify that 16K was detected and available to the computer. I then jumped to FC00 to start VTL-2 BASIC to make sure that still worked.
