A few weeks ago there was a post on KLOV asking what these chips were.
One of the replies to this was that they might be a PAL chip so my attention was caught.
I managed to borrow a PCB pretty quickly and determined that this was not a PAL chip.
A few users had already mentioned that the manufacturer made RAM chips and after doing some circuit drawing I found what type of RAM it is.
If you ever need to find a replacement for the above chip then look for MB81C68.
