It is time to see if we have saved this otherwise broken Commodore 64! And then do more testing!

Time to get the suspected RAM chip out, and install an appropriate socket! And then, well, perhaps this 64 will work! I wish the case was not cracked, but alas...it is...oh well...the top can always be swapped, but besides the crack this case is pretty wonderful!

Time to tidy and get the metal shield off of a Commodore 64...do not tell the FCC!

This wonderful test cartridge by Matthew Desmond and RetroRewind.CA has helped me find out which RAM chip needs to be de-soldered, and replaced...with a socket of course! The table is getting out of control again...shocking...I know!

I have the answer...indeed, the 8701 can replace the 7701...and there are other similar numbered chips that can be swapped...and now we are on to other error messages...other troubles...which might be RAM!

The hunt continues...

I am in search of a 7701 chip...but it seems to be an elusive quest...not at all sure if the 8701 is an acceptable replacement...

More testing...

Time to test a Commodore 64 that I recently acquired...it looks good, but it has a crack in the case...which is a pity!
