Hi! A friend of mine told me some of you may be able to help me. I trying to use a HM6116P-3 2kx8 SRAM, but cannot find a pinout anywhere. If any of you can help me, I'd be eternally grateful... BTW: (unfourtunately) I don't usually get a chance to read this group, so please reply via email. Also, let me know where you found the info... Thanks in advance, Bill Frazer cccbill@castor.ucdavis.edu
