Thank you Neil.
I can confirm this is the best version to use for general purpose use on the S4 but you may need to use V3.00 for later EPROMs.

Can anyone help me get a copy of the 2.93 8bit EPROM/EEPROM/NVRAM & FLASH library as the link above does not work any more? I know that i can use the later individual libraries but i often thransfer data between EPROMS, EEPROMS and Flash chips and this library makes the whole process much simple...
