All this talk of TRS-80's on the list (Those two S-100
Systems sound COOL!!!), prompts me to ask if anyone
remembers a garage project called "The Trash
Compactor".
Basically, some guy (a REALLY SMART guy!)
reimplemented the entire Model III logic Board on a
board that would fit inside a Model I case.
No, but I did start to do something similar -- namely modify an M1 to run
M3 software. I got 48K on the M1 mainboard (a fairly easy mod, since 64K
DRAMs were available), I got M3 BASIC running from EPROM, and I was going
to wire-wrap the disk controller, clock interrupt, RS232 port, etc
circuitry (I didn't care about the extra characters on the display or the
1500 baud cassette interface).
I never finished it though ;-(. The reason was that in the middle of the
project I went to a radio rally, and a chap had a couple of real M3s for
sale. Of course I bought one. I still have it.
