Did the modifications on my Packard Bell PB450 motherboard (Packard Bell Pack-Mate 28 Plus), however, I didn't solder the battery holder very well and accidentally trimmed the legs off. Good news is, I bought two of them, same thing with the capacitors, fixed voltage regulators, and the VRM mounting kit.
Voltage regulator mod (cleaned the rest of the flux off, mostly after the picture was taken):
Battery holder (will fix):
Systems from C64 to FX-6300.
