Title: paula plcc pinout
Post by: orange on November 25, 2017, 09:22:33 AM

couldnt find paula plcc pinout, so here is some of it. I've modified pdf from some other chip.

the pins with ?? are probably Vcc, Vss, GND?

I see. seems the same sorry situation as for the Denise chip, A600 version. I remember I did a similar attempt back some years ago. Using the schematics you can get all but 5 pins.
According to some notes I still have, pins 7, 20, 21, 40, 47 were not clearly marked on the schematics on the A600 service manual.
Actually two of these seem to connect to a buffer chip, but I'd not risk guessing who is who without an oscilloscope.
Anyone better luck ?
