First all this is my first post so i like to say hello!. I have purchased a willem programmer from ebay the PCB reads 2010 PCB 50 Have it connected to my laptop using the parallel cable and have a 12v 3 amp power supply for it. I have downloaded some pdf manuals from internet and the software 0.97g from your webpage, but not sure what version i have and the software to use. Like to burn some MC27c801 eproms the trouble is after setting the dip switches and burning i have fail to verify immediately always have tried in 10 different eproms and have the same problem. Tested selecting EPP ECP in bios and the result is always the same. When i read the eprom after burning i see that some data was programed but is only junk, not the data i loaded in the programmer software tested burning a text file and when read back the data in the eprom is random garbage.
