Tips
One user has reported success replacing a dead Conner CP-3045 hard drive with a standard Conner CP-3044 that had been formatted under System 6.0.8.
You can use a PowerBook 100-series AC adapter to run the Portable without the internal lead-acid battery. However, you will lose PRAM settings if you unplug the power (date, time, cache size, etc.)
Godwin <godwin@unixg.ubc.ca> says, "If the acid battery dies, one can bypass it and convert the Portable into a luggable. One needs 2 AC adapters - the original one and a 9V DC adapter. Take out the 9V DC battery and replace it with a 9V 1A power adapter. Then remove the battery and cover (there is a switch at the battery cover which we need to disable). Plug the two adapters in and viola! one of the sleekest Macs on anyone's desktop!"
