Subject: Wanted : Pinouts for 9311, 93L14, 8273 chips
I'm fixing some old HP computer hardware (a 9830 computer and
its 9866
thermal printer), and I've come up against a few ICs I don't
have pinouts
for :-(.
If anyone has them, could they fill in the tables below :
Fairchild 9311 (4 bit -> 16 line decoder?)

12 : q[2]
13 : q[1]
14 : /s[1]
15 : q[0]
16 : Vcc
/e Enable Input (active low)
d[0]-d[3] Data Inputs
/s[0]-/s[3] Set Input (active low)
/mr Master Reset Input (active low)
q[0]-q[3] Latch Outputs
Truth table
