Hi Kevin
I have tried USA and UK to get a new PRAM battery. ( listed around
$25 AUD) No luck. The next suggested solution is another
machine. The issue is that the lab equipment we use runs via a
serial port . So any machine compatible and with OS9 with serial
porting would do. Or is there a way of going from a serial port to
USB? I'd need to pull the HD from the old 7220 of course. Can you
help there?

If I remember correctly, the PRAM battery for that machine is a
square, quite expensive one. In the distant past I have made up a
battery with three AAA cells rewired to the original wire.
Alternatively you should be able to get an early iMac which will
run sweetly on OS 9.

Hi Bill,
I had one of those machines and I found that if the PRAM battery
died the machine would not start, so its worth putting in a new
one to be sure.

Folks,
I have an ancient 7220/200 attached to a bit lab equipment at
UWA. It's "dead". We think this might have had something to do
with a power surge then outage over Xmas.
We could change to a more recent machine, but it must be capable
of running OS9.
Could this be a dead PRAM battery? If co, any ideas on where
to get one appreciated.
Bill
