One vintage IBM 8MB memory module for PS/2 or older Thinkpad. Part no. 91G-0994. 70Ns EDO SODIMM. This information come from Google via the part number. If this info needs correcting any help would be appreciated. This was saved by a friend who saved vintage computers and parts. I previously sold a very early IBM Thinkpad laptop that weighed 7.5 pounds and was more than 2” thick. Happy to combine shipping.
