Hello, all: I just got my hands on a North Star system with a load of S-100 boards (mostly Vector Graphics boards; some of which labeled "BAD"). Does anyone have any info on the following: Vector Graphics: ZCB Z80 processor board, 12k PROM board, 16K SRAM board and 64k SRAM board, Micro-Disk floppy controller. I also need info on a Solid State Music video interface board (I think that I have a bad RAM chip on mine). TIA! Rich Cini/WUGNET <rcini(a)msn.com> - ClubWin!
