It appears I am clueless about Kaypro machines * The machines: 4, 4+88, 10, and 1 * Can't get anyone of them to boot. All but the 4+88 boot to a screen, but nothing else. I have a K1 CP/M disk someone from the list sent in 2009, and I tried that in all of them, to no avail. The disk on the 1, at least, seems to work, as it knows when I put in a non OS disk, and tells me, but nothing else. If it had a read error, would it not tell me? It does move the head and such when I insert the OS disk, so it appears to be reading it. Still, it never drops to a prompt. * Looking for parts. The 4 needs ESC and 7, the 10 needs 'right arrow', both the 10 and 4+88 need the little telephone jack in the KB. 10 needs a new fan, it's getting power, but no spinning. 4+88 needs fuse holder, and 4 needs reset switch. Missing a small screw on the KB catch as well. Before I start trolling eBay for a donor Kaypro, I thought I would ask around here. * The 4+88 needs major help. drives don't respond, screen does not come up, nothing looks alive. I'd ship it to someone who wanted to take a look at it, as it'll take me a year to start going through it. Or, maybe I should put the 4-84's guts into it (keeping the 8088 and extra RAM) and use the rest of the 4-84' for parts? All except the 4+88 are in good cosmetic shape. The outer top shell of the 88 is in rough shape, though the KB is in great shape save the RJ14 jack (or whatever they are called) My regret is that I should have tested the system disk I previously received as soon as I got it in the mail, but we moved shortly after receiving it, and have not had the items out of storage since 2009. So, the disk could have been mishandled by me or the movers in the interim.Jim -- Jim Brain brain at jbrain.com www.jbrain.com
