puppetmark #1 Posted October 7, 2009 I came across this and I thought I would pass it along. I also posted this in the 8-bit forums but this will be especially usefull to anyone doing the 4MB 72 Pin SIMM upgrade for the ST. It's a great little guide on identiying 30 and 72 pin SIMMS and the chips that make up the SIMMS. It even explains how to identify fast page RAM chips which is the required RAM for the STs. http://home.arcor.de/kickstart/TKA/Tutorials/Memory/SIMM.html#correlation Quote Share this post Link to post Share on other sites
