"The SCSI<->SMD configuration still eludes me, however. I know they exist (Adaptec ACB-55xx), though I've never seen one. Docs are *really* hard to get. Still looking for the docs for the Emulex MD-23, possibly the best darned SCSI<->ESDI bridge ever made: Handles four drives at up to 24MHz data rate. Smokin'. " They exist.. I'll check if a friend of mine still has any. I have a big pile of adapter docs. The only thing on line currently are for the Xebec 1410 and 1401. Next time I'm at my storage locker, I'll see if I can find the box that has all this stuff. I know that Tony asked me for some old OMTI info a LONG time ago.
