XXDP disks!! This sounds great Pete!

I have a MicroPDP but it is *not* an 11/23+. It has an 11/73 processor
(KDJ11-AB (M8192-YB)) along w/two MSV11-PL, 512Kb MOS RAM w/parity
(M8067-LB) an Andromeda UDC11 floppy/HD controller, a DHV11-A, 8-line async
comm. w/DMA, MUX (M3104), two DLV11-J, 4x SLU (M8043) and an Emulex TC02
controller.

I have no documentation on these disks, therefore, a few questions for you
and the others:

** Will the disks still work with the 11/73 and the third-party disk
controller?

** Is there an online index or something where you looked up those 'CZ'
part numbers or do you have the user's manual or same software in your
library to find the info above? (i.e., How did you know what they were and
how can I find the same?)

** Any online manuals for these diagnostics? Or, anybody willing to sell a
xerographic copy of them to me?

Thanks for the help folks.

Regards, chris
