This warms my crusty heart. The first Unix machine I ever used was a 3B1. Great keyboard!
IIRC, it only had a 10 megabyte drive, yet managed to have a pretty complete development and text-processing environment (i.e. cc/etc and troff/etc).
I really wanted to use GCC on it, but was never able to get enough of the code on the machine at the same time to get it compiled there.
