Commodore Pet ROM trouble... EPROM Substitutes...

Sorry, me again.

Mentioned TMS2532 Eproms are one of these Unobtainiums here.
Looking at the Pinouts I have in my databooks there are
little (minor?) Differences to the standard 2732's (besides
the different Program Supply Voltage). I couldn't find much
ressources online, but would it work if I made a small
adapter like "illustrated" below...

2732 2532
EPROM -> SOCKET
Pin(s) Pin(s)
1-17 -> 1-17
18 (E) -> 20 (PD/PGM)
19(A10)-> 19 (A10)
20(GVpp)> 21 (Vpp)
21(A11)-> 18 (A11)
22-24 -> 22-24

Please correct me, if I'm completely wrong and trying to do
something impossible.
2732's would be easy to obtain, and I have some
prommer-schematics and software handy. So it would be cool
if I could use them.

Regards,
 Wolfgang
