Some time ago, I was given a tape controller and drive for free. They work, and with a minimal set of commands from the SCSI specification, I've been able to read and write tapes. But I have a feeling there may be things about that controller that I haven't found out yet. Here is the information I have: Board says: "ASSY MW0210402" Sticker on one of the big chips says: "TOP ASSY: MT0210201-00F" Sticker on another big chip says: "Warr. Exp. 09/86" (indicates vintage) There are two 40-pin chips (with the stickers), an NCR5385 SCSI chip, an EPROM, and a big square PLCC chip which says this on it: L1A0691 2400001 RAA 8450 There is a 50-pin interface connector for the SCSI, another for the tape, and two smaller connectors - one 10 pin and one 15 pin. There are two LEDs (which never seem to light) and eight DIP switches. Does anyone know what I have here? Can this controller do more than record 40 megabytes of data on DC300XL tapes at 30 ips (that's what it does now). Should I bother calling up Emulex, and try to get a manual for it? And if so, what is Emulex's address/phone number? Once again, any information at all would be appreciated. Markus Wandel
