How do I know what resistors to pull and run to 5v?
Bikerbob wrote:REV H --- I think its R133 and R134 but with just those 2.. do I tie the ends of the resistors together and to the 5v?? I saw this..
https://atari.joska.no/520stm/4Mb%20RAM ... 0520ST.pdf and thats how I found the above resistors.. but I am not sure how I tie them to 5v now.

spiny wrote:OK dug it out of storage, it looks like there are only two resistors that need linking to +5v: R134 and R133
hope this helps.
