I recently replaced the power supply on a G4 and just because it was
easy I checked voltage on the 15 V (something like that) lithium dry
cell on back-bottom corner of the motherboard. It was way below in
voltage and clearly printed 10 year lifetime. It's a half length triple
C and it wasn't hard to find in the neighborhood. It had been running
the clock while the machine was shut down.

Booting from the Tiger volume after PRAM Zap is normal, the startup disk

The aberrant cursor behavior doesn’t sound like a PRAM related issue. More
likely it is a software conflict. Try creating a new user on the Leopard
volume and see if the the same behavior occurs for that user.

My MDD G4 has two hard drives, one with Leopard (10.5.8) and one with Tiger
(10.4.11). I run Leopard 99% of the time.
1. After archiving and reinstalling Leopard and all updates, the cursor now
exhibits aberrant behavior. It frequently flickers on and off, especially when
using Photoshop, and also displays as an 'empty' square or string of squares
through which the background can be seen. I've researched this problem
thoroughly, but none of the solutions I have found have worked.
2. One of the solutions suggested was to reset the PRAM/NVRAM. When doing this
in the typical manner (holding down the Command, Option, P, and R keys at
start-up) from Leopard, the computer starts up in Tiger from the other hard
drive!
What's going on here????
