Don't want to rain on your parade but how did you arrive at the figure of what it is worth. I know I have most of these and better but I would certainly not expect to receive anything close to $600 for them. I have a certain affection for my Apple II+ and it is a cool machine with some special features and a platinum A2-e but I can't see both of them going on E-Pay for much more than $150 even including the drives, duodisk or original.
We, in the vintage market, have to avoid over-inflating the prices of our computers. It could come back to haunt us. OK, Apple 1s at $20,000, Altairs at $6000, Imsais at $3000. I can accept that. But when you get to the common home user computers we have to agree on what is acceptable, not on some E-Pay price which was the result of a good presentation or bidder hysteria.
But enjor it and have fun with getting the beasts to work. Once I have them working, I am, I must admit, a fickle lover.
