Fixing Fat Angus
« on: January 23, 2025, 05:33:33 PM »
Hi all, I've been trying to fix my Amiga 500, which has been in the loft for many years.  Initially, it was getting as far as a white screen without the insert disk image.  As part of troubleshooting, I interested a Diag ROM.  The ROM seemed to get stuck asking to hold down a key on the keyboard or pressing the right mouse key. Both actions did nothing to progress the Diag ROM.  Trying to figure out what was wrong, I read some advice about reseating the board chips.  I did this.  Following the reseating of Fat Agnus, the ROM started getting stuck at "No memory found.  System halting".  Oh dear.  I tried removing Fat Agnus and it did seem like one of the pins was out of place.  After reinserting, I still had the same issue.  After a couple of attempts at reseating, it still had the same issue.  I noticed that it looked like maybe one of the pins in the socket might not have been making contact with the cihip, so I pushed it out a little and the bloody thing broke straight off the socket :-(

I was hoping for some advice on the best way to resolve this issue.  I'm not sure if I should have a go at desoldering and fitting a new PLCC socket to the board or if there is some other crafty fix that anyone knows that might allow one to fix/bodge/over come the broken pin?

Thanks in advance.
