PLA 906114 is a great IC
The one the flaw that this IC had, is the fact that in the tropics it easily went close to 70 Celsius which meant total Destruction of the IC if you didn't put the heat sink on it. Quite logical that in my country all C64s died because that IC failed.
It was wonderful to work on the Commodore 64
Because of the 8-Bit technology machine language it was easy understanding what the ICs did
It was quite easy; the whole machine was a relatively easy thing to learn in comparison to a modern x86 system
