I would like to know how you go about merging say 4 2732A eproms into 1
27128 EPROM. I use the copy /b prom1.bin+prom2.bin+prom3.bin+prom4.bin to
make the image and burn it onto the new eprom. But now where would I jumper
to the old board sockets to address the new banks of info on the new eprom?

The top 2 address lines on the 128. 00=first 32k, 01=second 32k, 10=third
32k and 11=last 32k. Providing that all the "32k" banks were all exactly
32k long, of course!
