ACML Posted August 1, 2017 Share Posted August 1, 2017 (edited) I'm having a 50% success rate programing some M27C128 EPROMs. The TL866A software (v 6.6) doesn't have my SG listed. I selected the AMD 27C128. The default voltage is 13.5v and the next increment down is 12.5v. The specsheet says 12.75v. Can I damage the EPROM programming at 13.5 vs 12.75? I figure better on high side??? Edited August 1, 2017 by ACML Quote Link to comment Share on other sites More sharing options...
Roydea6 Posted August 1, 2017 Share Posted August 1, 2017 Try the TMC27C128 @ 13.5V Quote Link to comment Share on other sites More sharing options...
ACML Posted August 2, 2017 Author Share Posted August 2, 2017 (edited) Think I solved problem. Set programming voltage to 12.5V, used a different USB port and now it works 100%. Edited August 2, 2017 by ACML 1 Quote Link to comment Share on other sites More sharing options...
