68K ISA project

I believe that the project you are interested in is the one done by Ingo Cyliax at Indiana University.  He developed (for a class I believe) an ISA form factor board that had a MC68030.  At one time I had all the artwork & schematics (I may still??).  A search brought up a couple of references, but the page at Indiana University seems to have been taken down.  It was a pretty good system, including interfaces for keyboards and mice (I believe).  It DID have ISA slots, and the ROM software worked against a standard IDE/Serial/Parallel board set, booting the disk.  The memory was fixed at 4 megs (I may be wrong at this), and used the synchronous interface of the MC68030.  The ISA portion used the async interface for the ISA timing, and an interrupt multiplexer multi interface chip (MC68901??) to handle the keyboard I/O.

The web site also included a frame buffer that used an alternate interface that was provided for.  I believe that there was an edition of Minix that ran on it as well.  I suspect that with a little work 68k Linux ought to work, as the MC68030 has an MMU.

Maybe someone can use this information to access the Wayback machine and get a proper pointer.

Hope this helps.
