Is anyone aware of a source for the Winchester MRAC connectors used for the disk bus and power connections on the Diablo series 30 disk drives? Alternatively, has anyone built something compatible using pogo pins or an array of contacts mounted to a circuit board that could connect to the drive?

I think the last time I needed power connectors I just watched on ebay for them
someone on eBay is selling complete bus cable assys

Thanks! I saw this cable but wasn't certain whether it was the right one. It does say Cable model 30 though

I was hoping to find a reliable supply of connectors or means to make them so people could easily mix RK05 emulators with Diablo drives.

I was speaking with the seller separately and it sounds like he is getting ready to list an inventory of Diablo 31's and 33F's at some point and has a smaller assortment of cables and power supplies. I would not be surprised if that data cable is compatible with the lot.

Edited: Nevermind. Looks like he already has the drives listed in the store.
 
gwiley and I have been working the problem. I have a stash of winchester connectors. the problem is my cables are mostly in a building I won't have access to until the end of June now.
I have a couple on cables I'm going to desolder so he can prototype an adapter.
An outstanding question is how common is a plug on the drive end of the cable from the interface in the cpu as opposed to a socket. I think the Alto was weird using a socket. Terminators
with sockets seem much more common than plugs and my tester cables use plugs.

If the cables get down to where they are $25/connector end, it may be worth buying from the guy for all of the associated hardware like the thumb screws that you'd be nickel and dimed
to death on buying new as components.

I need to take better picture, but there are a few up for the diablo cables up now under http://bitsavers.org/pdf/diablo/disk/model_30/cables_terminators/
Pictures of the RK03 adapters are under http://bitsavers.org/pdf/dec/disc/rk03/RK11C-RK03-Connectors/ they use unibus cables for drive/drive cabling
