I think some people are a little touchy. I have nothing against the 360/20 --
it was fun to program. But the /20 was designed twenty years ago. It was made
of discrete transistors and core memory. There is newer stuff in glass cases
in the Computer Museum. I really am amazed if somewhere there is still a /20
in production use. For the cost of power and maintenance alone, it'd likely be
cheaper to throw the 20 away and replace it, perhaps with a System/36 if the
software is mostly RPG or a PC XT/370 if it's in assembler. The /20 was a
minimal CPU onto which you could hang some decent peripherals, like a 1000
LPM train printer. But it's dumb -- less cpu power than an 8080, and with
typically 4K or 8K of memory, not much room to maneuver.
Writing a C compiler for this fine antique would be a tour de force, but it's
hard to imagine why one would even try.

PS: If you want to get rid of your 20, perhaps the Computer Museum would take
it for its collection -- it's a little weak in PDP-8 era IBMery.
