Has anyone seen these before? They seem to be a new take (just a shrink down) of the XT-IDE and an FDC controller that supports single density (FM) and 2.88 ED drives (along with the usual PC stuff). The FDC is interesting. I would have liked to have seen it be more like a CCIV w/ four drive support and addresses but given that most FDCs will not support FM this is a great step forward.
It also looks like someone tweaked the PAL code, originally decoded by Chuck G., on the SB CM/S upgrade to get rid of some of the incompatibilities...
