Hello from Gregg C Levine
Can any of you point me in the directions of a website that completely
discusses this operating system, PRO or P/OS? As I recall the DEC
Professional system was basically a shrunken PDP-11. Finding one of
course, would be a good thing.

The Pro380 used the J11 chip. The T11 was a totally different chip, with only
the base instruction set (no multiply/divide/floating point) and 8 or 16 bit
bus

The 380 had a J11, the 350 had an F11.  I *believe* the 280 was
somewhere between an 11/73 and an 11/53, and the 350 was somewhat
like an 11/23.

Correct.

If memory serves me right, you had P/OS (a menu-driven branch of the
RT11 system), and Venix, a somewhat Unix-like system.  Given some
work, one should be able to get standard RT working on it.

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

This is actually exactly what I have done.  The emulator is
available here:
