my Apple IIgs contains a Cirtech Plus Ram 8 (http://www.whatisthe2gs.apple2.org.za/cirtech-plus-ram) and an additional card Cirtech Romdisk GS (http://www.whatisthe2gs.apple2.org.za/cirtech-romdisk-gs).
I own the manual and software for the Ram card. Unfortunately I have no information or software about the Romdisk. It has, as on the photo, eight empty sockets for Eproms ( probably 27512) . The Romdisk would have a full capacity of 512KB.
Does anyone have information on how to program the Eproms?
Thanks in advance
