Hello Dave,
If you can get hold of a serial cable (null modem) then you can transfer the library to the S4 over the cable using the S4 driver for Windows.
An application note on doing this can be found on our website
here.
In order to determine which library you need for a device you need to look at the device list which can be found on our website
here. Searching in the document for "27C512" will highlight several results as this device is supported under different manufacturers. All references to this part name will fall under a heading in the document, this heading directly references which library version you need.
In this example it is the "S4 8 bit (EPROM) lib. V3.00".
If you have any questions, please contact me.
Best regards,
Neil Parker
