S4 COMPARE command
Posted: 23 Mar 2014 00:54
I am using a Dataman S4 with S4WinDriver version 2.17 and trying to repair and old device that uses Intel 2716 PROMs. What would be some of the reasons that the COMPARE command does NOT match all data in the PROM with the contents of the USER-RAM between the START and END addresses? Each time I run the command COMPARE and do not get the status message SAME, the data bits that do not COMPARE are usually at different addresses. Most of the 2716 PROMs COMPARE correctly but some do not. Can somehow this be corrected? Is it caused by a PROM that somehow became faulty? Dirty pins on the PROM? There are not to many things that can go wrong and I am running out of ideas. I would appreciate your help.
