Thanks Al! Yes, that's a very nice MC68030 station and well documented.
I've reviewed the files and the workstation PCB is quite large. It requires
a 4-layer PCB that is about the size of a PC/XT motherboard. I think it
would be very expensive to make these PCBs for hobbyists.
What I was thinking was more a smaller scale version of this without the
PC/AT bus interface and consolidated on to a smaller more affordable PCB.
Comes to mind - c't had a 68K ECB card in vol. 11/1985, p. 62f.
It is not a simple design, since it has to map the 68k bus to ECB, but uses
only one PAL. Drop me a note if you want the (German) article scanned.
There were also a 68000 based and a 68008 based SBC design.
