Not if those pin names are correct. !G is Output Gate, i.e. !OE. I'd
all the pins straight through, except 18, 20 and 21.
2532 socket 2732 ROM
18 A11 21 A11
21 VPP no-connect
20 !E (PD/PGM) 18 !E
14 Vss 14 and 20 (Vss and !G respectively)
Anything else is connected straight through
I *think* that'll work. The only difference is that this grounds the
2732's
!G (Output Enable) pin instead of rigging it high (Vpp
is usually
connected
to +5V for EPROMs that are wired for reading only).
Yep, well spotted.
