I have some 8-bit ISA 53c90a based SCSI controllers labeled "SCSI HB A8". Mine are made by "Advanced Information Concepts", but apparently they were also made by "Control Concepts". Unfortunately, mine don't have the BIOS chips installed. I have a picture of the card with a chip installed labeled "Ver-3.02 CCI 0991", so I know an 8k or 16k boot prom existed. Does anyone have such a card that they'd be willing to dump a prom image from (or let me borrow it to dump). KJ
