Hoping you can help me.
Can the TOP2048 program a "NEC D2716D"?

The TOP2048 can read the chip but not program it.
I'm using the latest TOPWINEN software and have used the following options "NEC/D2716 25V" and "???/2716 25V"

When I click detect I get ff,ff.

When I click program, the "OK" message flashes immediately in the window but it has not programmed at all ?!?


Some background....
- I'm using the latest TOPWINEN software.
- So far I've managed to program the following:
27C128
27C256
2532 (using modified dummy socket with a setting of 2732A)

SOLVED!!!!! SOLVED!!!!! SOLVED!!!!! SOLVED!!!!!

Had to do two things
1) Download / install TOPWINEN version 1.39 (Download the top2048 zip file from this site)
2) Set "Test Current" off. This is found under menu option SETING - OTHER.

Annoyingly for this 2716 eprom, I can't use the latest version and you have to set "Test Current" off each time you execute TOPWINEN.
