G540 Programmer

I am building a simple BCD to 7 Segment LED Display. I am using a PLD to decode the BCD & drive the 7 Segment display. I have written the Code using WinCUPL. Now I am trying to program a Lattice GAL22V10 PLD using a G540 programmer. The programmer reports pin connection errors. I have had this programmer for a while, but have not used it much. Everything looks good, but I get that error. I have tried to program my part by ignoring the error, but it appears that the part is not blank, after erasing it.

I have contacted the manufacturer in China, but have not received an answer.

Does anyone have any experience with this programmer?

Hi Dan

I have the G540 and I was never able to get it to program a PAL or GAL.

I'd be happy to program some ICs for you, others have been really helpful to me here recently and I want to pay it back.

I have a vintage 1980's Stag ZL30 logic programmer that is great at PAL/GALs. You would need to send me some blanks and email me the file.
