Macintosh 512k Board???

Posted by: Macintoshguy1984 on 2016-07-24 10:34:01 I have recently took apart my macintosh 512k and on the board right of the crt ( not the motherboard.) thats hooked into the crt. It says on the top test 1 test 2. Does this mean anything??? and the macintosh is a 521k with a 128k serial number.

Posted by: Macdrone on 2016-07-24 12:30:48 512k was a normal upgrade path for the 128 for more memory to be useful.  Did not even have to change the rear bucket.  Test stamps dont mean much, just Quality Assurance in the run is all.  That would be the power/analog board.
