The standard TI 4K DSR chip, the TMS2532, is becoming difficult and expensive to find. With that in mind, I think I have come up with a scheme to replace a TMS2532 EPROM with a 2732 EPROM (cheaper and easier to find). I need some of you Electrical Engineer "gurus" to take a look at this and see if it is correct. Two stacked sockets are used with the bottom one plugging directly where the TMS2532 used to be seated.
Top Socket is the 2732
Bottom Socket is the TMS2532
Top Socket Pin 21 (A11) is connected to bottom Pin 18 (A11)
Top Socket Pin 20 (Vpp) is connected to bottom Pin 21 (Vpp)
Top Socket Pin 18 (-CE) is connected to bottom Pin 20 (-CE)
All of the other pins are connected straight through.
