I decided to dismantle the Mini85 circuit to gain some desktop area for the next year. It was the biggest and more complex breadboard project I've ever done. I did not manage to build it in three standard breadboards, but I still find it small enough. With a single PAL (maybe a 16V8) I'm pretty sure it could fit the three boards.
The next step is use what I've learned from this Mini85 project add it to the PCB design and USBKeyboard and build a eurocard (100x160mm) CP/M computer.
Here is his last picture in this format...Mini85 "will be back" soon... in PCB format...
