And all those gold circuit board traces. HP
doesn't do things by
halfs!
It's funny, but all other 68000 MPUs I've seen have been either Hitachi or
"ST" (?) models. Or plastic PLCC models.

The battery in the bottom is for a battery
operated real time clock
and for use in a controlled shut down in the event of a power lose. It
won't run the computer for more than a few seconds. It's optional and it's
sort of rare, I've only seen it in a couple of machines. FWIW it was only
available in the 9826 (aka 9000 226) and 9836 (aka 9000 236) I think both
of th em machines that I saw it in were 9836s.
The compartment is far too big to operate any non-atomic RTC. And it features
a warning level about the high voltages. It measures something like 20?15?4
cm.
