I seem to remember these as being bridge controllers
from a SCSI host-port
to the FDD's. The company I associate with this phonetic spelling has no
'P' in the name, i.e. it's OMTI, at that time a subsidiary of SMS.
Because of the vintage, it would be wise to get some
documentation to ensure
that the firmware on your host board will communicate over the channel this
board requires. I've got numerous SCSI<=>hard-disk boards from various
vendors of the time, all claiming to be SCSI-compatible, and not a one of
them will work on a SCSI adapter to a PC, be it from NCR, ADAPTEC, IOMEGA,
DTC, WD, or TRANTOR. All of my boards were made before the original SCSI
standard was adopted in 1986. The hardware appears to be compatible,
however, so if you have any flexibility at your host-adapter firmware end,
you may be able to use the OMTI boards. That time-frame seems to align more
or less with the INMOS doc's I've had around from time to time regarding
their Transputers, so I'd say there's cause for hope, if not optimism.
Of course you're right. I should sometimes reread my stuff ... its OMTI.
An I think we are talking about the same boards. These babies have been
quite reliable, and I still use at least two on a daily base, but regarding
his need to share the cable with modern style hard disk drives it isn't
a real good idea to use 'em for a new design. Maybe one of the Winstation
drives.
