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?)

1 : O/
2 : 1/
3 : 2/
4 : 3/
5 : 4/
6 : 5/
7 : 6/
8 : 7/
9 : 8/
10 : 9/
11 :10/
12 : Gnd
13 : 11/
14 : 12/
15 : 13/
16 : 14/
17 : 15/
18 : E0/
19 : E1/
20 : A3
21 : A2
22 : A1
23 : A0
24 : Vcc

Fairchild 93L14 (latch?)

1 : ENABLE/
2 : SET 0/
3 : D0
4 : D1
5 : SET 2/
6 : D2
7 : D3
8 : Gnd
9 : MASTER RESET/
10 : Q3
11 : SET 3/
12 : Q2
13 : Q1
14 : SET 1/
15 : Q0
16 : Vcc

Signetics 8273 (10 bit serial-in, parallel out shift register)

1 : Q6
2 : Q7
3 : Q8
4 : Q9
5 : Q10
6 : Clk/ 1
7 : Clk 2
8 : Gnd
9 : Clr/
10 : Serial In
11 : Q1
12 : Q2
13 : Q3
14 : Q4
15 : Q5
16 : Vcc

Note: The unused Clock performs the INHIBIT function.

You are MOST welcome; delighted to have an opportunity
to repay you for the many times you've helped us.

Let me know if you need detailed tech data; I have the Fairchild
Data and Application Books and the Signetics Data Book.

I even have a fair bit of 9300 ICs, but alas, no 9311s and
only the regular power 9314. Probably no 8273s but I can
have a look.

Good luck & thanks again for all YOUR help!
