Among my regret list are:
1. HP 150 and 9121D, which I traded for:
2. Macintosh Plus in perfect condition
3. 6x NeXT Cubes which I profited on heavily, but liquidated the last three at fire-sale
prices. However, I at least managed to trade for a Color Turbo NeXTStation and a few
peripherals
4. VAX 4000-500, which was way too big, but very fun
5. VAXstation 4000/VLC in perfect condition
Of all of those, I think I'd take the HP 150 back first. That touch screen was just
so fun.
