Running 2BSD (was Re: PDP-11/93)

Mostly, I noodle around and see what text games/apps I can port from the modern era back to a true 16-bit machine (with limited process memory space). Decades ago, before it was inexpensive to run UNIX at home, I set up an 11/24 with dual RL01s. ISTR spending $300 on the 11/24 and at least that much for more memory and a KT24 (I did not own the tape drive - I did the initial setup on work hardware then took my own packs home to run them). I went with Unibus because 22-bit Qbus peripherals were still quite current with current prices, and the 11/24 was, compared to other options (11/44, etc), inexpensive for a machine with enough disk and memory to run UNIX. At the time (mid 1980s), one could set up an ample RT-11 box for well under $1000. UNIX on DEC hardware took a lot more resources than $1000 could buy you in that era. Simultaneous with these experiments, I was running UNIX on VAXen at work - Ultrix 1.1 on an 11/730, Ultrix 2.mumble on a MicroVAX II, and before either of those, 4BSD and System V on an 11/750. My first experiences were on hardware that my employer paid well over $100K for. I was happy to have something to run on my own that was around 1% of that. -ethan
