Hi all,
I need some help with a recurring question I have. I've got a Mac Plus, which has been upgraded from a 512K, and it is in great condition. Everything works the way it should, it's a great little machine. The only issue I have with it is that the case is yellowed only on the rear, the case that was changed during the '512K to Plus upgrade'. The front is still the 512K case, with 512K serial number. From what I know, this consists of a replacement of the motherboard, floppy drive, and rear case.
I also have a 512K with a front that has seen some slight damage, and it trips the circuit breaker when it is turned on. I got a startup chime from it before it tripped the CB. Looking inside, everything looks good, but the battery did leak and the analog board looks to have sustained slight damage. The only thing that looks wrong is some some of brown transformer has a bubbling inside it, and under the surface does not feel uniform. I think this may be the problem. The motherboard looks pretty good, no obvious issues.
I need your help in choosing one of the following courses of action:
- Leave them both alone and try to repair the 512K at a later date
- Take the motherboard and rear case from the 512K, and put it onto the Plus, effectively downgrading the Plus back to its original spec (what about the floppy, will it work or need to be swapped?)
- Put the 512K case on the Plus and leave it at that
- Some other option that may be good
Any help would be great, thanks guys.
