Amiga 1200 faulty CIA fix

Got this A1200 that was working fine except for some random crashes. Upon performing the Amiga Test Kit, it showed a fault in a CIA timer. The 1200 has smd components, that means you need a hot air station to remove some chips. The following pictures shows the removing process of U7. Then I added a PLCC socket for the new CIA ic. Machine fixed.

  1. Very interesting post, and also love how you socketed the chip.
    Is hard to solder this sockets and not melting the plastic close to the pins. Nice you where able to prune your system from the pesky Tic’s and weevil.
