Will this program 2732 eproms and etc?

I just want to know if the one I posted will work...I live in canada and the shipping will *Insert nasty word here* me in the ass

Short story NO. This is based off the Willem programmer design based on the specs. They will READ 2732s, 2532s, 2716s, etc. but they are very, very, very unreliable when it comes to programming them. They just don't have enough power to do it.

This has been discussed at length, just search for Willem programers and you will see.

Save your money and buy a decent programmer. BP Micro 1100 series programmers come up on EBay and EBay.Ca all the time. They will do the job. Willems will work on CMOS EPROMs but when it comes to the old NMOS technology, you might as well program it with a hammer.

How doesn't it have enough power? it runs off of outlet power. I could see it not programming 2532's as they require an odd voltage but I would think 2732's etc would be fine?
 
This is really pissing me off that I can't find something. I don't want to wait and wait and wait for something old ass to popup. I'd like new and old support as I wouldn't just use this for older things.
 
God dammit, Another fucking day gone by and I still don't have an eprom programmer on its way to my door. Shipping will probably take close to 2 weeks so I want to order one ASAP so I can start using it and getting familiar with it. I wish people would give me some kind of proof as to why these will not work. I'm getting many mixed opinions and don't know who to believe and it's really pissing me off as I wanted to have one ordered last week.
 
The Willems use a DC to DC converter to jump the 12VDC that you plug into it to whatever the programming voltage is required. Unfortunately the circuit pulls too much current when programming old NMOS devices and the voltage drops during burning. At some point the voltage drops sufficiently that the part will not be fully programmed. This is a well known defect in the Willem design, which most people can live with because they are programming modern CMOS parts.

The down side is that in my experience when the buring fails about 75% of the time the EPROM is damaged and is useless. Since less than 1/3 of the 2732's I tried to program actually burned correctly this can be an expensive proposition.

Real World Number: I burned a set of Joust ROMs. It took 37 ROMS to get a complete set of 12. Of the 25 ROMS that didn't burn 21 were damaged. 4 were reusable. At $2 a ROM it was not going to take long to burn through more in ROMS than it was to buy a more expensive burner. I bought a BP Micro for $11 w/ $19 in shipping off EBay. I sold my Willem to somebody for what I paid less shipping.

That's why I said, save your money until you can afford to buy a real eprom burner. It wil be cheaper in the long run.

Just so you think I'm the only one that doesn't like the Willems: http://s107351202.onlinehome.us/cgi-bin/Blah/Blah.pl?m-1202012451/#

Problem being is I don't really know how to look for one. Most old old ones use an ISA card which is often not sold with them making them useless. I also want to be able to use newer eproms, eeproms,flash roms etc. I'd buy a batronix batupo but it is a bit limited with only 32 pins and I don't believe it does flash(I could be wrong)
Also how do you know its based of williems?
 
anyone have any suggestions as to what to get then?

Everyone has their favorite device, and will sing it's praises. Mine is the wonderful Needham's PB-10. It's an internal card that goes into the computer with a simple ZIF socket on a cable to plug the EPROM into. The software runs in DOS and is easy to use and well written. It's fast, reliable, handles all the old chips (2532, 2716, etc).

A lot of people like the pocket programmer - I've heard great things about those. The Data I/O unisite is another popular choice.

I know of nobody that actually *likes* the Willem programmers. They're cheap, but that's about all they have going for them. I knew they were unreliable burning 2732's, but I had no idea they actually damaged the roms - that's news to me. Have you tried sending them to someone with a real programmer to try? I've recovered roms damaged by overvoltage by programming them full of zeroes and erasing them again. If you still have your damaged ROMs, I'd be interested in trying, just to see what's going on.

Keep searching. You can't equip a workshop overnight - we all accumulated our test equipment over the years, piecing together stuff as we went. Try going to hamfests - that's where I got my very first EPROM progammer, an ancient Data I/O series 22. It worked for a while for me, until the internal power supply finally failed. I really liked that programmer, despite it's limited buffer and inability to program anything over a 27256 or so. That programmer was so old that the manual included instructions on connecting a paper tape reader. I wouldn't mind finding another one just for old times sake, that was a fun device.... convert your binary to Intel hex, cat it out through the serial port at 1200 baud...

I don't want something old though. I'd something new but also something that won't cost me a ton of money. I also want this soon...
