It's 8V AC (so there's no pinout

transformer of some 11 ohms internal resistance (and yes, that is
important according to the technical reference manual which I happen to
have).
So like some HP calcs the adapter only charges the battery, it won't run
the machine with a dead/missing battery.
No, the charger will usually run the 110. Probably because the 110 uses a
lead acid battery and they tend to go open when they go bad unlike NiCads
that tend to short (and short out the PSU).
As I expected the battery pack is totally dead. I doubt I'll bother
replacing the battery. I've never seen these cells at any of the usual
electronics suppliers around here. I don't doubt that one of the
specialist battery companies has them, but their prices are too rich for me.
You can probably order the batteries from Digikey or someone like that.
My personal preference is TNR <http://www.tnrtechnical.com/default.asp>.

Failing
that, would it be safe to remove the battery and connect a 6VDC
power supply to the battery terminals?
Should be OK, but of course you'll lose the memory contents (including
the A: ramdisk) and configuration data when you turn the PSU off.
I had it running for a while earlier today. Everything seems to be working
as it should. Nothing out of the ordinary beyond the QWERTZ keyboard and
PAM being in German. The only application installed in MS-Word, which is
English.
