I've been looking for some 14-pin Winchester MRAC connectors for powering my Diablo 31 disk drives (rebadged by DEC as the RK03), and it seems what was once a common plug and socket is now quite a specialty order.
After searching a while have found that only(?) military/aviation suppliers have them, and they require a minimum order of $400 which is of course not very useful to me.
I've looked on Farnell, Frys and other large electronics websites to no avail. And there are no google hits at all when trying to source them where I live (Australia).
As I only need two of the socket ends (designated MRAC14S), would anyone perhaps know of where I could obtain them retail rather than a wholesale amount? Or as a take-out from old equipment? I would also like a 42-pin MRAC42P plug for my second drive, but that can wait.
If I can't find them I'll most likely machine up some work-alike substitutes from a block of ABS or nylon, but I guess I'd like to avoid that much mucking around, as I have a long, slow road of other jobs ahead me before I attempt to bring them up on a working PDP11, and currently I'm only looking to acquire bits to facilitate this.
Here's a picture of the MRAC14P power plug on the back of the drive, and a diagram of the MRAC14S socket I found in a catalog.
Thanks for any help
Steve.
