I bought a used programmer which appears to be a Dual Power Willem/PCB3B, as it matches the picture posted here exactly. From the date codes on the chips, I'd guess it was made in 2002. I'm having trouble getting started, as I did not find any sort of user manual or instructions here. I downloaded the epr097ja.zip software. Is that the one I should use on Windows XP SP2 with the PCB3B?
What should be turned on first, the computer or the programmer? Plugging in the power to the programmer with no computer connection lights only the yellow Vdd LED, as I would expect. I believe I have the correct cable, a printer extention cable with all 25 pins wired straight-through. Connecting the computer and plugging in the programmer produces all three LED's on, so I immediately unplugged the power as the 7805 tab got hot quickly. I'm connecting to a ThinkPad T-23 notebook computer. The switches and jumpers are set up for a 2716 EPROM as shown on the software screen.
I'd appreciate any help to get started using this device.
I found the manual in the answer to another thread at:
Fiddling around with the parallel port settings on my notebook computer finally fixed the problem with all three LED's on. Not sure exactly, but it seemed to start working after changing the setting in Windows to "always use interrupt".
