homebrewed 32-bit cpu?

[Grant Stockly]

I've thought about it.  I actually entered half the schematics for the 
Magic-1 into my schematic program.  I was going to produce some PCBs for it 
for a kit.  I ended up giving up because I needed to spend time on the 
Altair effort.

A goal of mine would probably be a TTL 8080 or completely a 
transistorized  (as in pbysical little black dots : )  ) 8080.  The idea 
behind that is it could be an extension to the Altair kit...

I have thought about a 32 bit CPU built like the Magic 1, and in fact drew 
up the schematic for the ALU.  I thought it would be fun to build a 
computer using parts available in 1975 that was capable of decoding an 
MP3.  For speed designed a schematic for a 32x32 combinatorial 
multiplier.  :)  I think I estimated it would draw 5A (just the 
multiplier)...  ; )

And no, it would not be the same if it were in an FPGA.  : )

The 8080/transistor computer would have an LED for every transistor.  Can 
you imagine how cool it would be to single step that thing?  : )
