Circa ~1983, I saw a pair of CBM-IIs with 80-column displays and dual
500KB 5.25in drives.  They were being used by a law office for word
processing and some kind of database application.

Don't recall much about them ... it was one of my first encounters
with "micro" computers, and I wasn't allowed to touch anything.

By 1985 that same office had converted to IBM PCs.
