Yes. The original Apple SCSI card went through three ROM revisions, called "revision A", "revision B" and "revision C". The ROM part numbers are: rev A: 341-0112A rev B: 341-0112B (I think - I don't have one any more) rev C: 341-0437A The first two versions are 2764 EPROMs (8Kx8). The rev C is a 27128 EPROM (16Kx8). Revision C is required for use with GS/OS, or to support Apple CD-ROM drives. -- David Empson dempson@actrix.gen.nz Snail mail: P.O. Box 27-103, Wellington, New Zealand
