I used the SWITCHAR feature for a long time. I was working in CP/M and HDOS on my H-8 at home (1980) and UNIX on the 3B20 at work (Pacific Telephone). I didn't touch a Microsoft product until 1985. The "PC" was way out of my budget when it first arrived in 1981.

Ah, the 3B-series. I had the good fortune to have a 3B2/300 desktop (a cast-off from Cornell Univ.) as my first UNIX computer, around 1985 or so. SysV, ah, those were heady days -- I had built a homebrew (wire-wrapped) Mot 6809 microcomputer a few years before, wrote a monitor and disk handlers and ran FLEX-09 on it, but once I learned C I wrote a 6809 CPU emulator for the 3B2, and that actually ran faster than the real 6809!

Anyway, there was a huge 3B20 unit (also at Cornell) that amazed me... great technology for its day.
