Eprom programmer question

I checked out the GQ-4X Willem EPROM programmer, is it any good? I see Riptor uses it and said that it does burn 2532 eproms wiht no problems, also the manufacture is only about a 20 minute drive from where I live so I can pick it up and save money on shipping cost. Just want to get opnions on this programmer, I have a few older games and would like to get a programmer that has the ability to burn 2532 eproms and it says that it can be powered by USB power or external power.

Mixed results from what I have read. A lot of people love them. Check out the AtariAge forums though. Tons of people having problems with them.

I have a GQ-4X, and I personally think it's a great burner, and a REALLY good deal for the price. I haven't had to use it with an external power supply (though it's nice that it has the option), and I've burned 2716s, 2732s, as well as newer stuff with no problems.

I haven't heard anyone with one complain about it, though I've never been a regular over at AtariAge, so it's probably worth checking what people that do complain about it have to say.

I have burned hundreds of 2532/2532A with my willem. I bought mine with the external power pack and always use it. Seriously, for about 100 bucks you cant beat this programmer.
 
I am thinking that I will probably go with the willem GQ-4x, it looks to be able to do basically all I need and being able to do the 2532 eprom is something I really want. Looking on ebay there are lots of older eprom programmers for a decent price but most seem to be sold as is with no software or instructions and not knowing if they work properly makes me not want to spend the money on something sold "AS IS". Riptor I am was just wondering about the external power supply you have for yours, did you get it with the programmer and if you did how much did they want for it and if not where did you get it from?
 
I also have a Willem GQ-4X and it's worked fine for me so far. I haven't tried any 2532's but it's good to know Riptor has been able to get them to work. :) I also should pick up an external power source for mine. I've run into at least one situation where the software was telling me I should have external power applied.
 
I e-mailed the manufacturer of programmer and they said you can connect a DC 9V external power adapter to it if needed but it doesn't need an external power source but I think you would be better to have an external power source.
 
I think I have narrowed the programmer search down to 2 programmers, the Willem gqx4 and the batronix usb chip programmer. I don't tink the batronix can burn 2532 eproms but eh gqx-4 can. If you had to pick between the 2 which one is a better choice?
 
Mine came with the power supply. I bought the programmer and power supply together from the manufacturer off ebay. I think it was $110.
 
Does the Batronix USB Chip Programmer support nintendo eproms (playchoice, vs boards, and regular nintendo boards.) was just wondering. and is this a reader too. or is the a separate unit all together.

thanks in advance

Exactly.

The early eproms need 25V power for programming.

USB provides a nomimal 12V voltage,
so trying to push it to 25V makes it unstable.
(...it wasn't designed to do this ... )

I'm almost completely clueless when it comes to electrical speak, but I know a guy once made me a power cord adapter for my electric dryer to function in my apartment. All I had to do was hook the two cords up to two seperate phases of the electrical to go from 110v to 220v. The reason I bring this up is because I have an external hard drive on my computer that runs off of USB, but it has a jumper USB. If USB is 12v will the jumper now make it 24v or close enough to the 25v needed without being unstable. Just thinking maybe they have two USB plugs, but I could be way off base.

As pointed out already, USB power is 5V. These programmers produce the other voltages by DC-DC conversion (e.g. a charge pump circuit). The problem is not the voltage but the current required at the higher voltages (21V or 25V). The USB current is limited and may not be able to provide enough power, so an external supply is wise if you're programming older chips.
 
So does the TMS-2732 have the same pinout as a regular 2732?
 
Sorry to bump an old thread, but what I have is basically an EPROM programming question :) I finally got some blank eproms, and have a couple boards I want to work on. The programmer I'm using only does 2700 series (2716, 2732, 2764, etc), but I need to do a couple 2532's (I have some TMS 2532 eproms). I've also got an adapter someone built that lets you read a 2532 using the 2732 pinout. Can I program with that adapter too? It's basically a pair of sockets with jumper wires to flip 3 pins. Thanks :)
 
Yes/No.

There are 2 different types of 2532 - the 2532 and 2532A chips.

The difference is in the programming voltage. Now I'm going off memory here, so don't get pissy if I get it wrong, but IIRC, 2532 = 25v programming and 2532A = 21v programming.

You'll have to choose a 2732 with the right programming voltage to program the 2532 chips with the adapter. But, even then there is no guarantee that your programmer will be able to program them. You just have to try to figure it out.

OK, thanks. I won't get pissy :D Anyway, the programmer does 12.5, 21 and 25 (I can tell by looking thru the various chips it will program). It looks like the 2 I have are both TMS 2532A's. Just wanted to make sure it wasn't gonna blow the chips before I tried.
