Hi,
I've played around with a model 20 (and an Infoserver 150, which is based
on a model 10, I believe. Maybe my hints also apply to the model 80.
Open the machine, look for something that looks like a battery pack. Check
the voltage. You might find it empty.
It may be a pack consisting of three NiCd AAA-cells, which can be replaced
with a similar pack of NiMH cells. The charge circuitry is similar.
