EPROMs for 2600 4k - AM2732B on TL866II+ ?

[ericpskl]

Can anyone confirm whether or not they are able to program AMD AM2732B EPROMs on a TL866II + programmer?  This model is in the supported EPROM list for the programmer, but I haven't been able to program any of the EPROMs that I purchased from eBay. 

 

They don't appear to be rebranded or painted (acetone test).  Spec sheet shows VPP at 12.5 volts, so the TL866II+ should be able to handle them just fine.  Programmer works fine on other EPROMS.

 

Any ideas?

What is the error you got???

I tried to program some AM2732B using my willem programmer and all works fine.

The error log out of Xgpro isn't very helpful:

@pcrock, what are the voltage and timing settings that you used to program the AM2732B on your Willem?  I've tried to increase the programming voltages and timeouts, but nothing worked.

Thanks!
