Yes, it was. 20 years or more ago.Because it wasn't there.
Worthwhile, to who? The OP perhaps, but surely we would all be better served if his energy and skill was directed at something besides inventing another wheel....worthwhile work.
This 68008 system on a protoboard was intended to be only an experiment and proof-of-concept for the real 68 Katy, which I had planned to build on a custom PCB with a full 68000 CPU, a CPLD for glue logic, more RAM, an SD card, and ethernet. But this experiment was perhaps a bit too successful, and now I’m wondering if it really makes sense to go to the effort of building the “real” system if it’s going to be essentially the same thing, only faster.
