I remember replacing Lotu 123 with Quatro-pro :p
I remember (3 PCs before having a HD..) having to record everything on cassette.. about 15-30 minutes to record 8kb >.<
First PC with HD was about 1984.. 286.. Whopping 12MB hd.. could never fill the whole darn thing... (was Epson PC..and had DOT MATRIX Printer too :D).. and the mouse (M$) was $90 (2 button).. :/
Lol. Dot Matrix. Yup. The mainstay.
What OS was it running? DOS? Commodore?
Now here is something to date you — your computer might be in the American History Museum on the Mall in DC. They had a section for computers — IBM PC, HP calcs, etc. Worth a visit if you are in town.
