Hi!
I have to read and eeprom and as I see on the net seeprog is a popular programmer for many eproms. I decide to make one after I found the schematic.
I made the pcb and found some problems on it.
Here is the schematic and the pcb what I found on the net.
As I figured out the schematic didn't meet the pcb. After I made the pcb and put all together I figured out does the programmer does not recognized by the software from Elnec. I found the problem with the diode on the LPT pin 2 and 15 was wrong configured. After the correction it was fine. But the programmer still not programming the eprom.
Does somebody have some experience with this type of schematic?
I need help to solve the problem whit this please.

Thanks.
