I was gifted and old Laser XT machine recently and have semi started to mess with it. It is very inconsistent when reading the hard/floppy drives. Sometimes it will boot other times I get errors. I cracked it open last night and found several issues...
1) the battery had leaked. I removed it and cleaned up the flowers it left. Doesn't seem to have eaten much of anything so I think I'm OK there. It's a 3.6v with solder leads I'll have to order. In the mean time I suspect that the only thing that will happen by NOT having the battery is that the time won't hold. Is this correct ?(there is no CMOS RAM in this box.)
2) Looking inside the back-plane I appear to have a nice layer of green moss on some pins. What is the best way to remove this crap and prevent it's re-occurrence ?
3) The keyboard is very unresponsive. I suspect it is a membrane one , although I did not crack it. Is there a way to rehab these type keyboards or is it trash ? If it does turn out to be a slider(although I am fairly certain it is not) What is the cleaning method there?
4) The TTL RGB monitor that came with it is also not working. It just shows a solid horizontal blue line dead center of the screen. Any hints on where to start with that one would be appreciated.
Thank you...
