I have several HP 1000s and two original keys but I'm not sure what you're asking. But yes the keys in all of the HP 1000s are interchangeable, at least in the six or eight machines that I've tried. I don't have one here but IIRC they are Corbin keys and they are brass with a round head. FWIW I just got some keys made and it was a real hassle. I tried Home Depot, Lowe's and a couple of othe large hardware places and they didn't have any blanks of the same type. I finally went ot a small local hardware store and they found some blanks made by another company (ILCO?) that they could make keys from. The new keys have a trapazoid shaped head like that usually used on house keys and they're nickel plated steel so they look completely different from the original keys. The locks on the HP 1000 simply hold the front panel closed. But the main power switch is located under the cover. If what you have ARE HP 1000 keys I could use them but it's probably not worth the cost to ship them from the UK to Florida. Joe At 09:51 PM 6/6/03 +0100, you wrote:
