I managed to find one of these yesterday in a pile of Q-Bus and Unibus boards that I picked up. I've exhausted all my "net mining" techniques, and have only managed to confirm that it is a SCSI controller. Does anyone have any specifics on it? Based on it's model number of "UTS25" and the fact that there was also a "QTS25" controller I'm suspecting that it is a Unibus SCSI Tape controller, but that is just a guess. Based on what little I've been able to learn, MTI is "Micro Technology, Inc.", unfortuntly I've not learned anything else. For a brief description of the board, it's a Quad-Height board with a 50-pin connector on it. There is one chip with the Model number on it "UTS25". The one EPROM says "MTI-U/B A3.4". It has a Z80B CPU from SGS, and a Zilog Z0853606PSC chip. However the chip that really caught my eye was a WD33C93-PL. The WD chip is the same as an Amiga 3000's SCSI controller. At the moment the main thing I'm looking to know is what exactly it is, though how to configure would be nice also. Thanks, Zane healyzh@ix.netcom.com
