On things like that, I often don't even try to rescue any suspect ICs or
even passives, just cut them off close to the PCB with a very fine pair of
sidecutters, and then desolder the stub of pin.
On Tony's advice that's what I do too.
First thing is to make sure anything you remove is
replaced with a good
quality socket, and if necessary that you can repair any damaged tracks
with stripped wirewrap wire or similar. How adept are you with a
soldering iron? I used to do this sort of thing for a living, and I'm not
too far away if you want someone to take a look at it.
You're not too far from me either, assuming you live near York. My last
repair ended in a stalemate - everything checks out with regard to
schematics, even the 2 tracks I managed to break, but I still have a dead
MTX512.....
Having said that I haven't checked the ICs for the correct voltage yet; I
know the PSU is OK 'cos it powers my working MTX OK.
Once I've finished re-laying the floor in the dining room I'm going to have
another go at it so watch this space :)
cheers
