I will watch it with great interest. I have one too but mine also has a pair of 8 inch
floppy drives attached in a separate cabinet. Never powered mine up either. The 29000
processor would have been in a unit under development not within this chassis. The unit
contains emulated microprogram ROM. The 8080 loads microcode into the emulated ROM cards
which were connected to the unit under development with ribbon cables.
You guys might like this one. I didn't
realize AMD has been around that long.

What the item description doesn't say is that this is a development
system for Am2900 series bitslice chips. The Am9080A (equivalent to
Intel 8080A) is the only the host processor.

2900, not 29000. The 29xx is a bit-slice CPU design made up of a
bunch of chips. The 29000 is a single chip CPU that came later.
