We have been busy designing and building a 68030 based workstation
for the last few months. 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.

Enjoy, -ingo
