Hi there PIC'ers I have an old TX motherboard with quite a few DRAM chips on it which I could use in latter projects for storing data. I was wondering if there is anyone who could help me with the pin-outs. I've searched the web, with little success. The two chips are MOSTEK MK4564N-20 and OKI M3764A-15. From the little info I have found these are 64K chips. Any help would be appreciated.
