Re: Doubling up BIN files to burn to EPROM

You load the file into the buffer, it takes up the first half. Then
you load it again, only you change the starting address of the load to
the second half.

Darn near every programmer, even those funky ones that you have to
IN#x in an Apple II .. prompt you for where you are either loading, or
programming, the first would be $0000, then next time, you would load
it at $4000 because a 27256 holds $8000 bytes.

Typically I have found, when using a 27128 in place of a 2764, the
upper half is loaded on power up if the socket is wired strictly for a
2764. That being, the unused pins on the 2764 are not connected to
anything.

If you use a 27256 for a 2764, you just load it 4 times. $0000, $2000,
$4000 and $6000.

In theory, you only need to pick the segment that will actually load,
but since you may not know, circuitry differences can cause different
things to happen than what you might expect, etc- you program in
double, quad, etc.
