Limited indeed. As I said, I made it work in 256KB of RAM, but it
wasn't enough room to really work.

That's why I stuck with 2.9BSD for so long... my first split I&D
machine was a Pro380 ex-VAX Console. I have only recently aquired
an 11/53 board from a DEC comm server (with real PDP ROMs installed
so as to act as expected). Since I _do_ have megs of Qbus RAM
and MSCP controllers, etc., I'll be using 2.11BSD with that.
I did solve my RL02 space problem in 1994 - I imaged my real magtapes
to disk files on my own SPARC1 (via a MicroVAX w/TU-80) and put up
a PDP-11 emulator and got it all running - ISTR it ran at about 30%
of the speed of the real hardware - on a 12MHz SPARC!
