I doubt you'll be able to use anything other than a RD51 drive - as this ancient V7M doesn't yet support newer drive types. You might be able to put some of the system files on an RL02 - but I haven't confirmed there's a RL02 boot loader on this kit.
Interesting. Given that it's MSCP it should be just a matter of mapping out the sectors and such. But to be honest, naah. I have a copy of Ultrix-11 on 20 or so floppies here, I think I'd just use that on an RD54 and be done with it.
Oddly enough I do have a copy of Pro/Venix 1.0 that would fit on a Pro/350 with a 5mb hard drive. Slow as *dirt*, you could literally watch the hard drive seek back and forth with the little arm on the side. But it did work. Unfortunately I only have a pair of Pro/380's these days so I'd have to use Venix 2.0 which is probably less fun :-)
Back in 1983 the PDP-11/23-PLUS was a relatively *new* machine. There's later versions of Ultrix-11 (V2 and later) that added support for the 11/73 and bigger drives - look on the Unix Heritage Society site under Unix Archive. There's a downloadable installation tape for Ultrix-11 there.
Speaking of which, has anyone ever written a loader to allow one to copy a SIMH tape file onto a real tape drive via serial like that pdp11GUI allows you to load up an RL02/RX02/MSCP drive? I do have a working TK50 and a TK70 (and know how to fix them) and they are pretty nice units.
