Anyone got any info on the above board? motorola 68000 CPU, DRAM, ROM
& some IO (2*6821 PIAs, 2*6850 SIOs, 1* 6840), and a bunch of
switches, all on a MultiBUS I card. Also has "master/slave D16 M24 I16
VOL   1982" legended.
Nothing helpfull showing up on a Google so far.
(received it amongst a pile of DEC manuals & TK50s rescued a month or
so ago)
