Steven, Yes, it sounds like they are looking for boot software. It should be on the hard drive, but maybe it is corrupted or someone took it off. Check with "Sharkonwheels" on _www.vintage-computer.com_ (http://www.vintage-computer.com) , he is more expert in Kaypros after 1983. I am more into the 1983 versions. The Kaypro 10 came after 1983. You can post on this site and maybe someone will offer to buy them from you. They could be used just for parts of course. Note if you have anything else for them - software, accessories, cables, etc. That can help the sale, along with any other info - where did you get them, past history if known, etc.. This is probably the best overall site for such vintage computers. I post under GADFRAN. Good luck. Keep us informed on how you progress.

I repaired the LVPS in the first unit and it comes up (?) but I think it is waiting for something ( like a BOOT disk ? ). They both ( machines ) have one half-height 5 1/4 floppy drive and one half-height 10 MByte hard drive. So far both of the CPU boards do exactly the same thing, after RESET it puts up the following prompt on the CRT; * KAYPRO 10 v1.9e * Anyone know what if anything it is waiting for ( I can't believe it wouldn't BOOT off of the hard drive, but I don't know any better ) ?? The 10 MB Ready light for the hard disk does come on ( for what it is worth...). Better yet, anyone want a couple ( or one ) KAYPRO 10s to screw around with and add to your collection ? They are built pretty tough ! Make an offer that will cover my Super Bowl beer fund and you're in business ! Because of their weight, probably limited to domestic USA shipping ( from Southern CA ).
