Posted - 08/27/2006 : 12:42:20 i am trying to program a sst 39sf020. i have 2 and both do not work so far with the programmer. i have the the dip switches correct. it reports the chip as 5v so i left the jumper in on the adapter.
what am i missing?
the zif is locked down with the adpter at the top near the lever.
do i need to set jumper on the programmer? i have had good luck with a handful of eproms.

I guess that you are using a wrong adapter. The PLCC32-DIP32 adapter has no jumper on it, which you should use.
The one with voltage jumper is PLCC32-DIP28 adapter, which you should not use.
