I'd start by downloading simh and see what storage any of the early DEC system support in the simulations. That will not be 100%, as systems like the PDP-9 did not originally support a disk, so the one Ken Thompson used had been a PDP-7 disk spliced by DEC CSS on the 9. So the UNIX V0 work we had to move the code from one simulator to the other (which was easy in SW - for the work we are doing at LCM on real HW, we are just emulating with a modern disk).

Also, FWIW: might try the Classic Computers, Rescue mailing lists and maybe the simh list too (although read the source first ;-).

Greetings,

I'm looking for a list of all hard disk drives that DEC supported prior to ~1970 or so as part of some research I'm doing for my talk this fall in Lillehammer. so far, I've only found one listed in a pdp-9 brochure (the RB09 listed in the PDP-9 handbook). Are there others? I've seen a reference to an RA01, but have seen no details on it. It appears that Rx## is the pattern to look for in that era.

Alternatively, if someone can articulate the XX## naming scheme of the time, that would be great. I've seen Dx## for different communications modules, for example, but don't know if I can generalize.
