My Thanksgiving project this year (besides eating dinner): restoring a 7800! I had to replace the TIA, the 6532, and all the console switches, but it's working now! The last step is installing an A/V mod ...
Not too difficult. There are four legs on each switch, two per side. To make it easier, I heated each of the two pairs with my soldering tip and pried them out of the holes once the solder was liquid. I then cleaned out the holes later and soldered in the new switches.
