Hi I am trying to read a 24c16b chip from a Grundig radio with a willem programer only a cheap one , But I am having some trouble removed the chip with hot air and attached to a test clip with isp lead to dip.
Put this in the 24c Chip slot
But when trying to read it comes up with No Ack Device Comand.
I have checked all connections on the chip and all are fine and I have selected 24c16 as the device but it will not read am I doing something else wrong?

Tryed it with a 93c chip last week and read no problem.

Btw this is a dual power willem so uses plug voltage and usb I have tryed both and on there own but still get the same error.
Thanks for any help.
