Here's the pinout of a 4164: _____ NC [o V ] GND Din [ ] /CAS /WE [ ] Dout /RAS [ ] A6 A0 [ ] A3 A2 [ ] A4 A1 [ ] A5 Vcc [_____] A7 The 'V' is the notch in the package and the 'o' is the mark for pin 1 that some of them have. To help count: NC = pin1, GND = pin16, Vcc=pin8, A7=pin9 Gerrit Message was sent through the cbm-hackers mailing listReceived on 2016-12-16 17:00:03
