WIllem programmer help

I'm new to this and just bought this board: http://sivava.com/.

Wish I would have realized you have to have a printer port. Anyways, my question has to do with attaching the psop44 adapter. How do I know what is pin1 on the adapter, and which orientation is the adapter installed? I can't wipe this chip out......

Ok guys, I figured that out using my multimeter.

Now I have a new problem. I am trying to read an intel 28f400 chip. The BIN I am getting does not look correct and when compared to what it should look like it is verified incorrect. I am not getting an error message either. Is there anything in particular that I should be looking for in the settings? I have moved the switches to the correct positions. If I run the chip ID, it says intel 28f400 B. I'm not sure why my bin is incorrect.

If I run the chip ID, it says intel 28f400 B

It should be OK with read result.

I'm not sure why my bin is incorrect.

Why ?
Sometimes bytes in source word are swapped .
Send to my mail read result and your expectation.

You were right! The bits were just swapped. I have made the changes to the BIN file I wanted to make. Before I write the chip do I swap the bits again?

You can do with Willem SW, Action > Swap Byte

Before I write the chip do I swap the bits again?

Yes. first swap for edit , second swap for write
