This workstation was designed to be used in our computer architecture class and has the following features: Hardware: 16Mhz 68030 procesor 1 1Mx36 (4Mb) SIMM Slot 32Kb of SRAM (we use a Dallas SmartWatch socket to make it NVRAM) 64Kb of EPROM 8 and 16bit ISA Slots 68901 MFP with AT-type Keyboard interface mostly discrete easy to get parts Monitor: debugging monitor (trace, one breakpoint) serial download 2 register sets (can debug program in monitor while keeping OS state) supports Paradise VGA cards and IBM-AT compatible keyboards boots from PC floppy (currently only from 720Kb 3.5" floppy) and IDE written from scratch We printed PC-boards and build about 20 of them and they seem to work OK and we are slowly getting all the software ironed out. So at this point I have made the schematics as well as PAL and monitor images available for anonymous ftp on our ftp server: cs.indiana.edu:pub/goo/mc68030/{schem,software} Future developments may include ethernet booting (via bootp/tftp). We have a Minix for this board that supports the MMU on the 68030, but since Minix belongs to Prentice and Hall, we can't make it available like the board schematics and monitor. We could make a patch kit available, but that would be a mess, since it is based on a heavily modified version of Minix-ST 1.1.
