PB 165 clock madness

[croissantking]

I only needed to open the Date and Time control panel under System 7.1 and it sorted itself out. I am really intrigued by this bizarre solution as I was sure it was a hardware problem. Obviously, the clock needs some sort of initialisation routine after the battery is replaced, but the code was not put into System 7.5 and later, probably got forgotten about. I wonder if the 7.1 Date and Time control panel will do the proper reset under later OSes.

Thanks @rollmastr

Apparently 7.5 is kinda buggy on these machines, I just saw your other thread about the missing gray scales on the menu bars and such.

Just to update with more detail - I had the PB apart this evening to swap out some RAM. This means I had to unplug the cable that goes to the interconnect board and therefore also the PRAM battery. On putting it all back together, the clock was in fast forward again.

You do have to boot into 7.1 to get it reset properly - opening the older Date & Time control panel under 7.5.x won’t do it. So keeping a 7.1 System Folder on the hard drive is a must if running a later OS.

As long as the backup battery keeps the RTC powered, I don’t expect it to go haywire again.

So - would a Disk Tools disk with the appropriate control panel be a solution for setting the clock?
I’m just mindful of the practicalities of trying to boot an earlier version on a Powerbook that’s set up with 7.5.
I have a friend with a 165c that this presumably applies to - we’ll see. Need to order more VL2330s…

Yes, a disk tools floppy ought to work too (but one should verify that).

Another solution would be just to use 7.1 instead of 7.5. I’m actually considering this.
