Hi everyone,
One of my viewers at RetroIsle.com has asked me to try and find out any information about a possible engineering prototype SID he has acquired.
He writes: "I am a Commodore collector and have either an engineering prototype C64 or what I believe is a super early consumer sale unit. It has many ceramic package chips including a 2082[-dated] SID. Instead of a country and production line stamping on the bottom of the chip’s package, it just has a numeric code on it ending in an “X”. Do you know of anyone who might be familiar with the code on the bottom of this chip? I can’t find much information about these SIDs online. I had also heard in Commodore circles that the early SID chips were USA made. I am not certain about that information but would really like to hear it from someone who knows for sure or has documentation.".
Pics provided. Any ideas?
