Compaq Portable III

[John D. Reeve]

Hello All.  I have a Compaq Portable III (286) that is functioning fine, except that the clock loses time (it seems to basically stop) if the machine is off more than an hour.  It does remember its setup information, however, and there are no error messages during boot-up.  I imagine it needs a new battery - where would I find one for such an old machine?  The battery does hold a charge for at least some time, according to my meter readings, so maybe it isn't the battery?  Thanks for any help.
