I just bought an enhanced willem with the 16bit 40-42 dip adapter, it has not extra power supply plug, it just has USB and Parallel port input.
I can read all (27c1024, 27c160, 27c800, 27c000) eproms ok, but i can't write any of them. I ever have the same error : 0x000000 chip = 0xff or 0x00 and buffer 0x00 or 0xff It depends about the bin file i want to use.
Well, I used all the combinations i could do with the wires, the programmer, the adapter. I ever get an error.
I can read all of them, so I suppose the Willem works...
I'm really desperated.
If you can help me, please !!!
