DATAMAN SYSTEMS DMS2000-M1 Data bus: 16-bit, ISA Size: Half-length, full-height card Hard drives supported: Two MFM ST506/412 drives Floppy drives supported: Two 360KB, 720KB, 1.2MB, or 1.44MB [Image] CONNECTIONS Function Location 34-pin data cable connector-floppy drive J1 34-pin control cable connector-hard drive J2 20-pin data cable connector-drive 0 J3 20-pin data cable connector-drive 1 J4 4-pin connector-drive active LED J5 MISCELLANEOUS TECHNICAL NOTES The DMS2000-M1 has no jumpers to configure. This controller is compatible with the Western Digital WD1003-WA2. One minor incompatibility exists between these two controllers. If the hard drive contains more than eight heads, the WD1003-WA2 numbers heads 8 through 15 as 0 through 7 in the medias ID fields. The DMS2000-M1 controller numbers heads 8 through 15 as 8 through 15. You must reformat the hard disk if you are replacing a WD1003-WA2 due to this incompatibility. This problem is not manifested in drives with less than eight heads.
