KEE WILLEM EPROM PROGRAMMER ARCADE ROMS SERIAL
You stick the prom in your breadboard, and wire it up to the appropriate ports and pins of the Arduino, which bit bangs the prom and returns the results though the serial connection of the Arduino. An Arduino, breadboard and some quick scripting quickly takes care of that problem with this Arcade Rom Reader. The problem is that its kind of an odd ball part now, and typically only (even) more expensive EPROM programmers can read them. convert your binary to Intel hex, cat it out through the serial port at 1200 baud.Wanted to read some 82S129 bipolar proms, and why not, they were very common in the 1980’s arcade scene. I wouldn't mind finding another one just for old times sake, that was a fun device.

That programmer was so old that the manual included instructions on connecting a paper tape reader. I really liked that programmer, despite it's limited buffer and inability to program anything over a 27256 or so. It worked for a while for me, until the internal power supply finally failed. Try going to hamfests - that's where I got my very first EPROM progammer, an ancient Data I/O series 22. You can't equip a workshop overnight - we all accumulated our test equipment over the years, piecing together stuff as we went. If you still have your damaged ROMs, I'd be interested in trying, just to see what's going on.

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. I knew they were unreliable burning 2732's, but I had no idea they actually damaged the roms - that's news to me. They're cheap, but that's about all they have going for them. I know of nobody that actually *likes* the Willem programmers. The Data I/O unisite is another popular choice. It's fast, reliable, handles all the old chips (2532, 2716, etc).Ī lot of people like the pocket programmer - I've heard great things about those.

The software runs in DOS and is easy to use and well written. It's an internal card that goes into the computer with a simple ZIF socket on a cable to plug the EPROM into. Just so you think I'm the only one that doesn't like the Willems: Įveryone has their favorite device, and will sing it's praises. That's why I said, save your money until you can afford to buy a real eprom burner. I sold my Willem to somebody for what I paid less shipping.

I bought a BP Micro for $11 w/ $19 in shipping off EBay. 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. Of the 25 ROMS that didn't burn 21 were damaged. It took 37 ROMS to get a complete set of 12. Real World Number: I burned a set of Joust ROMs. Since less than 1/3 of the 2732's I tried to program actually burned correctly this can be an expensive proposition. The down side is that in my experience when the buring fails about 75% of the time the EPROM is damaged and is useless. This is a well known defect in the Willem design, which most people can live with because they are programming modern CMOS parts. At some point the voltage drops sufficiently that the part will not be fully programmed.

Unfortunately the circuit pulls too much current when programming old NMOS devices and the voltage drops during burning. The Willems use a DC to DC converter to jump the 12VDC that you plug into it to whatever the programming voltage is required.
