One was inordinately proud of one's IBM XT Luggable. Two floppies, and a slot to fit an upgrade to 640k. Very nervous about busting something when I put the clone card in, but off it went.
I earned a bunch of money one weekend when a factory's CPM computer went TU the day before the changeover to a new PC based Novel Network. After repairing the computer, I called on a university that was the custodian of Kermit??? I think. Translated the disc format to the new 5 1/4. Then from CPM. I will never forget the relief I felt as the company's entire stock and parts lists poured onto the new hard drives.
