Around 1989 I wrote a PC program that replaced an Epson HX20 storing injection molding machine programs on small cassettes. 2000 I got a call the molding machines had been sold and the old IBM PS/2 ditched. The new owner asked me if I still had the program. I re-mounted my old QIC streamer sleeping in a box, installed Borland Turbo Pascal in a DOS box in OS/2 and could recompile it from source. Got the same price as I originally sold it for again ;-). Still in use. The Epson HX20 is gone though...
