Well, I think I might have solved my hard drive mystery. Chalk it up to me having been too young to remember the hardware clearly. Armed with the info you gave me above, I did some calling around this morning to people that might have a clue as to what happened to the hard drive. Near as any of us can figure, the hard drive was never owned by my company... the backups were aquired when we bought a software company that developed the accounting package we used (which we later continued work on in house). So the hard drive belonged to the software company, and those guys kept their hardware, we just aquired the software rights. So now that I know there is no mystery hard drive for my 5110... I have to give some thought to if I want to sell the system. With this recent eBay fever over things like a TRS-80, I am pondering if I can get a pretty penny from my 5110. I could REALLY use the money towards a house purchase. (I've got the 5110 with both Basic and APL, a large assortment of manuals, a few tapes with software on them, and the 5114 floppy drive unit. I should also have a printer around, but I can't say for sure if the printer is still operational). Time to do some hunting on the possible value... and if that value is enough for me to part with it (it holds a bunch of sentimental value to me, as it was one of the first computers I ever played with... possibly THE first, I'd have to compare timelines against the Apple II I used in the late 70's) -chris <http://www.mythtech.net>
