At the risk of raising the blood pressure of the purists on this list, I have a controller board out of a Corvus Omninet Drive (marked 8012-10970, 8010-?492-01 REV A. which I scrapped many years ago to use the cabinet and drive to back up my Cromemcos. Sorry to confess, I also pulled a few small parts off the board over the years, however, most of it is still complete and it could either be put back together if one had another one to compare, or perhaps someone could use the major chips on it (WD1010, Corvus 8115-03023 REV B, etc.) Also have a few old AT controllers with WD2010B's on them, not socketed though. Any interest? 2nd question: Does anybody know anything about the HD interface bus Cromemco used with their early IMI drives (7012 - 8" with transparent cover, 5007, 5018 & 5021 5 1/2") and the WDI/WDI-II controllers? I'm just curious if the same interface was used in any other systems (single 34 pin header, 7 units max, differential servo clock supplied by drive, so it doesn't look like SA1000). Interesting aside: when Cromemco finally went the ST506 route with the STDC controller, they made a replacement HD board available to convert the IMI 5 1/2" drives to a standard ST506 interface. Finally, I also have a Corvus S-100 board; looks like it might be a host adapter for a disk drive of some sort. Only markings are Corvus S-100, 8008 REV K, copyright 1980; 11 TTL chips & a 34 pin header. Anybody know what it is and/or want it? m
