Hi Marty
Many of the original 8080 processor cards were replaced
by newer Z80 cards. One can recognize these by the fact that
they have a 16 pin dual inline socket ( looking like a
missing IC ). This connected the data bus of the processor
directly to the front panel.

Yes many replacement CPU cards were made. The sad thing is that so manu
Imsai & Altair CPU boards were thrown away :-(
If you use a replacement CPU card just make sure you disable any of the
"extra" functions such as POJ & MWRITE.
