New subject: [pups] DEC PRO or P/OS

18 Nov 2003

Well, those programs emulate both the CPU (which *is* the same as
those found in the PRO systems), but *also* the surrounding stuff
like disk controllers, serial controllers and so on.

It would not be (that) hard to add "PRO" emulation to SimH, if some
sort of hardware specs are still available.

cheers,
	Fred

 Hello (again) from Gregg C Levine
 I take it this means that the software written for those things, won't
 run on an emulator normally running as a member of the regular PDP
 family of machines? Such as the SIMH PDP-11 emulator, or the E11 ones.
 Mr. Wilson, (John), mentions the operating system for the PRO, on the
 PDF file that describes the E11, both versions as being copyrighted,
 and mentions the company name.

 The 380 was pretty much OK in my recollection. 350 was downright  slow.
  RD5x drives did not help here..
