I've got an original Macintosh 128K, bought it brand new myself in 1984. SN is F4281SXM0001, which, according to another thread, decodes as; F = It was made in Freemont CA. 4 = It was made in 1984 28 = It was made in week 28 1SX = Is the sequence number M0001 = Is the model number All the original disks and manuals, MacWrite/MacPaint etc... MSWord, MSBasic, imagewriter cable, appletalk network and cables. I just plugged it in an played a game of Sargon (chess) and lost, so it seems to be working well. The internal disk, 400K I think, has a hitch is it's get along, so you need a paperclip to assist in the eject. It's got an external 800K drive as well. Some of the floppies are corrupt, it's only been 20 years! What would a guy ask for it if he wanted to sell it, and where would he go to do that (other than eBay)?
