I would like to flash a 28f256 chip with my willem. Do any TSOP56 adapters work with the willem? I found this, but I'm not sure if it will work with the willem or not. http://www.mcumall.com/comersus/store/c ... oduct=4214

Thanks. It's PCB 5.0E. I tried dumping both chips, and the dumps from both chips were identical with the exception of one byte. Is that normal, or do you think I dumped them wrong?

I have two 27c010 eproms I want to dump before they die of bit-rot, but I have a few questions before I do. I have a willem 5.0 programmer, and I'm not exactly sure how to set it up. I moved some jumpers around the last time I used it, and that was several months ago. If I have some jumpers in the w...

It should be blank. When I do the blank check, it says it is.

Do you mean to use the jumper to connect A19 and P1? I did that already.

Edit: my bad. I guess the chip wasn't blank after all

I have a willem 5.0e programmer with 0.98D8 software, and I tried burning my m27c801 with a file, and I get Error at 0x000000 Chip=0x00 buffer=0x03 I have the dip switch set like the picture, same with the jumpers. I even did the A19 - P1 jumper. Since that didn't work, I set the willem to pcb 3.0B ...

If I had a Willem pcb5.0 with a tsop48 adapter, would I be able to program a 39vf800a tsop?

Thanks
