PDP-8/m Memory (still more)

OK, I've been working on this for the past several days trying to see if data is actually being written to the core. However, I have run into a bit of a stumbling block. What is the following Chip, and does anyone have a pinout? S7316 DEC 6380A The MA lines go into it on the G227 board. 1=GND 8=Vcc +5V I think 4,7,12 are all inputs. I assume the 'S7316' is the manufacturer part number? Zane | Zane H.
