Nice machine (even if the 80 series are my least favourit HP desktops :-)). I assume you've discovered http://www.hpmusuem.net/ which has a lot of docuemtation (and software I think) for this machine. The good news is that such keyboars were usef by many manuifacturers, not just HP. The bad news is that all of them suffer from the same cracking. Trying to mend the pluger is difficult becaue putting the keycap onwill try to force the pluger apart again. One thing Ihave not tried is to file down the stem of the keycap so that it's a loose fit in the plunger, then repairign the plugner and gluing the keycap to it (with a 'weak' glue so it can be separated again if necessary). The reason I've not tried it, BTW, is that the keycaps are much more machine--specific than the plungers, so I dont;' want to risk damaging them. I don't think these keybaord spares have been available for some time (and AFAIK nobody is still making them). -tony
