  1. I am trying to insert a 2732 EPROM into a location where a 2532 currently
    should exist. I have programmed a 2732 EPROM with the appropriate code. I am
    sure that I can install this with a few pins changed, but I can't seem to
    get it right.
    Here is what I did
    All the pins are identical except the following:
    2532 socket. 2732 EPROM
    pin 18 ---------> 21
    pin 20 ---------> 18
    pin 21 ---------> 20

    Has anyone done this type of adapter?
     

  2. This is what think you need:

    2532 socket 2732 EPROM

    21 (VPP)-----------not used
    20 (/CE) ---------------------------- 18 (/CE)
    18 (A11) ---------------------------- 21 (A11)
    GND 0V ----------- 20 (/OE)

    Obviously you can use pin 12 for GND 0V.
