Thanks Paul. I found an srec2bin converter and ran that.. it created a 1K bin file. I
then opened that with a hex editor (slick edit).. but alas, no readable strings.

I would convert it to a binary image if you could and then look at it with a binary
editor. Most binary editors I have seen show the data in hex and also have an eye catcher
on the right with the ASCII equivalent to the code points. Trying to find strings in
S-records would be a bit painful.

Just posting this here in case it reaches eyes not in

I decided to embark on a project that involves burning a 2708 EPROM.
I've never messed with EPROMs before, so I decided to practice. What
I have is a Microworks 2708 'burner' that came with a SWTPC 6800
machine I have. I figured I'd start by learning how to read 2708s.
I only had one 2708 lying around to use. It was installed on a
homebrew 'Dynamicro' board (also known as Jon Titus' MMD-1). It's
strange because the MMD-1 doesn't use 2708s. This board also had a
bunch of ICs on it that are not what the MMD-1 design calls for. So I
thought this'd be an interesting EPROM to read anyway, since it might
yield a hint as to what the builder was doing with this board, or if
they were just using it to store random ICs.
Anyway, I fired up the 6800 with the chip in the ZIF socket of the
Microworks board and read the contents into memory. I then punched it
back out to my PC terminal as S records. That's as far as I got. I'm
wondering now how to actually dig into the contents a bit for clues as to what it is.
I've seen posts in the past from people who were able to find strings,
etc that sort of help as clues. Does anyone know how I'd go further here?
Really curious what was on this one.
Thanks!
Brad
