Fingers Crossed for 2021 ...

2020 was the worst! COVID kept the museum closed for much of the year and a mains water pipe bursting causing a flood kept us closed for the rest. 
We're hoping to re-open in the next few months ... fingers crossed! Read More >>>

This expansion board connects to an IBM PS/2 computer through the MCA bus. It allows the user to attach a Hitachi CD-ROM drive using a proprietary external 37-pin D-subminiature interface. Unusually, despite being designed for an MCA bus the card has a label indicating that it is only compatible with MS-DOS 3.1, 3.2, or 3.3 on an IBM PS/2 model 50, 60, or 80. It explicitly states that it is not compatible with OS/2. An ADF options file is required for the card to be configured in the PS/2 setup menu (attached).

This card was also supplied by RM with their M Series PC286/386 when an external Hitachi CD-ROM drive was specified either as a standalone workstation or as a CD-ROM server for RM-NET 3.1
