Hi guys,
Picked up a couple IC-2001-146-6 sound boards. Working on piecing together a Robotron. On one of these particular boards, it's missing IC10 entirely - socket and all. I was curious to find out where I can replace IC10 PIA or even if there's a standard chip number I might order some from Mouser or digikey.
Would be interested to find any kind of repair kit for these sound boards as the parts on them are quite old. Not sure if either works yet as I pretty much am still in the collecting parts stage.

PIA is a 6821, made by a bunch of different manufacturers.
