The PLCC100 (not 84 as I earlier thought) socket finally arrived and after much solder sucking the board is ready to accept the new one.
New socket soldered in and success - all working again.
A word of warning for anyone attempting this, the asic can go in the wrong way around - luckily I checked before powering up - the writing should be the right way up when in the machine.
I'm now considering using a 18650 battery with a battery conditioning and charging circuit as the battery backup. Anyone any thought on this? Fire risk?
Mike.
Edit, how do I remove the extra attachments? Every time I try I end up with more!!
