Reading a ROM

[Dave Frederickson]

Can an EPROM programmer read a ROM?

Sounds like a simple question, but maybe it isn't.

Here's an example:
Suppose I'd like to copy a 128k-byte ROM for a Portable PLUS. This ROM comes in a 28-pin DIP package, however, the largest EPROM in a 28-pin DIP package is only 64k-bytes.

So how is the ROM read?
