Anyone interested in an Arduino based ROM dumper?

That programmer on eBay appears to only have support for windows. It also needs a parallel port I think. Can't beat the prize though!

Anyway, my main motivation for doing this is self education. I was just trying to drum up some supporters for the project;)

If I wanted to support classic arcade boards, how many types of chips would I likely need to support? Do older boards use very similar chips?

lilshawn:
there is probably 20 or so main eeproms, but the requirements between manufacturers to read/write them varies greatly.

some need 5 volt, others 6, 12, yet still others 24 volts. most of the logic is all 5 volt though.

the advantage to a universal programmer such as the "top" series Chinese programmers is that all that is taken in account and is automatically fed the proper voltages on the proper pins to do your reads/writes.

is there any particular reason you have to run linux? if all you want to do is dump ROMS, and for what i have no idea since probably 99.9% of game roms are dumped in mame already... it's not hard to set up an old windows machine to do it. there is no speed advantage anywhere. eeroms transfer at a speed easily attainable by even the first 80c86 computer.

I'm a supporter of open source software and hardware. I choose to run GNU/Linux.

I'm considering this build to educate myself.

lilshawn:
fair enough.

I would look at finding a general purpose rom such as and start from there.

you will probably find that roms such as:
27C010
27C011
27C101
27C020
27C040
27C080

are all the same (electrically and logically they are the same.) except the end read/write address is different in each one.

alldatasheet.com is your friend.

maybe you could email steph at hobbyroms for some help?
