Otari MTR-90 MKII / DTR-900 Transport cards interchangable?

[bjoneson]

Trying to get a DTR-900 back up and running. Does anyone know if the transport cards are interchangeable w/ MTR-90 MKII?

I understand they're essentially the same transports, but not certain if the cards are identical.

I'm not sure.
I will check asap.

The Mitsubishi X850 and Otari DTR900 are very similar.  This is part of the webpage in regard to the Otari MTR90:

Mitsubishi and Otari collaborated on the design of the X-850 and X-880. The tape transport of both machines was derived from the Otari MTR90 Mk II, modified to handle 1" tape. Some mechanical parts were interchangeable between the X-850 and MTR90, the PC cards in the transport control section were manufactured by Otari and with two exceptions (the capstan servo and master CPU cards) were interchangeable between the Mitsubishi and Otari machines. The section of the X-850 service manual concerning transport adjustments was a verbatim reprint of the corresponding section of the MTR90 service manual.
