Most programmers do have a DC-DC converter (or multiple), even Willem programmers.

Completely inaccurate, I've never had a problem programming any EPROMs with any programmer that uses the USB for power. I tend to use an AC adapter regardless, but you can certainly do it without.

maybe it depends on the size? 27C256 compared to 27C040?

No they require the same programming voltage. There are some simple programmers that lack step up circuitry, so they cannot program eproms using a 5v power supply.

so it all depends on the programmer?

If the chips you want to program are specifically listed in the programmers supported devices list I don't think you have to worry too much about it.

alright i noticed that for the cd it doesnt say it is compatible with windows 7, but other postings of the same programmer on ebay say that it is? do you think that it is just because when it was released windows 7 wasnt out? is there a big difference between windows vista and windows 7 for the programmer hardware?

no im not making an earthbound im too much of a noob :) earthbound is my favourite game, but it would be really cool if someone made earthbound for the nes (not earthbound zero)

try going to the manufacturers web page and seeing if they have win7 downloads for that specific programmer.

so can I ask what ya are up to in particular?

well http://www.topwin6.com/Top853Det.html

It dose not list win7 in particular, so it may or may not work idk.

btw if you interest is just owning a specific repro cart there are people who will do it for less than the cost of the programmer

thanks for finding that site, why would it not work on windows 7 compared to XP?

well a guy at the end of this thread could not seem a similar programmer from the same company working on 7 so idk
