Hello,

I have a VP-490 programmer and I"m trying to program some Atmel 29c256 chips.

Every time I try to program something other than 0xFFs it gives me the following message:

  Device Address:0000003FH Device Data:FFH Buffer Data:5BH
  Auto Program fail!

Please help!

Thanks

Hello Again,

1. I"m using the latest release of software (4.7.0 - 6/9/2016)
2. I"ve tested with 7 different ICs, all with the same result.

Any more ideias ?

Thanks

Hello again,

As requested I"ve sent some photos to your email.

Since I also have an old Wellon programmer (VP-280), I"ve installed the old software (v4.3.3) and tried to program these chips. All 7 of them were programmed sucessfully with it, so all the chips are OK.

Best regards
