I've been struggling with an old box with lots of help from your different experts and I've learned a lot.
It seems that my soldered in Dallas clock is dead or dying and since I have nothing to lose, I'd like to try to change it, replace it or put another clock in its place or someplace it will work.
I have a lot of old computers in various states of decay available to me - many of them much younger than my old PI PC.
Is it possible to put a new clock in?
Is it possible to put a different type of clock in?
What should I be looking for in my scrap heap?
Are there "plug-in" clocks?
I'm doing all this so I can really get to understand how it all works and rebuild these older sets for a group of people who don't have access to computers so they can start to learn word processing, spreadsheets etc - and also for youngsters who want to learn to use a music sequencer...
All the best
