2716 EPROM to 2513 Character Generator socket

Postby nekonoko » Oct Fri 03, 2008 6:12 am

I'm trying to adapt a 2716 EPROM (containing a character set dump from a 2513) for use in an ADM-3A. Does anyone know which pins I need to wire up to make this happen? I've already programmed the 2716 with the character data, I just need to figure out the shim socket.

I do have datasheets for both chips. This is what I *think* I may need to do:

Pins (2513 -> 2716):

4 - (Out 1) -> 9 (Q0)
5 - (Out 2) -> 10 (Q1)
6 - (Out 3) -> 11 (Q2)
7 - (Out 4) -> 13 (Q3)
8 - (Out 5) -> 14 (Q4)

14 - (Address 1) -> 7 (A1)
15 - (Address 2) -> 6 (A2)
16 - (Address 3) -> 5 (A3)
17 - (Address 4) -> 4 (A4)
18 - (Address 5) -> 3 (A5)
19 - (Address 6) -> 2 (A6)
20 - (Address 7) -> 1 (A7)
21 - (Address 8) -> 23 (A8)
22 - (Address 9) -> 22 (A9)

24 - (Vcc) -> 24 (Vcc)
10 (Ground) -> 12 (Vss)
11 (Chip Enable) -> 20 (G), 18 (EP)

The burning questions are whether I should start with Q0 on output (believe I have this resolved), and if G/EP should be bridged to chip enable. Or anything else I may have missed ;)


Thanks much!
