Long live Clipper -- one of my first paid gigs. Amazing platform to write (compiled!) console-based applications with a DB living locally or on a networked drive. Something which does not exist anymore as a market.
They are much faster to operate and more efficient for CRUD type apps then GUI based ones.
What were you doing for 30 minutes?!?
Either way, that would be a hell of a high end system for that time.
Before 5, they had season names, I didn't mention to be using Clipper Summer '87 in 1987, rather having used it.
