Format is BINARY. If you need a different file format e.g. hex, then you can find convertors on the web.

All Eproms are 2764 type.

The files were verified by programming a new EPROM set and installing in my Xpander with no problems.
I do not have any other code versions so please don't ask.

If you are going to work on vintage synths then use a vintage EPROM programmer! Files created using a Data I/O 29B with Unipak2B & Promlink s/w.

EPROM Revision history can be found in the Service Manual. 
I have not verified that these work fully in all applications.
These files are provided in good faith to support the vintage synth community. 
No Warranty. No liability is assumed for any application or damage incurred while using the code.
