Hi,
Can support for the CY7C291A UV eraseable 16Kbit PROM be addedx to the software?
Can it be done with a devices.txt line or will it need more work?
It is very much like a 12.5v programmable eprom so I think it should be fairly straight forward ;)
The data sheet can be is here https://4donline.ihs.com/images/VipMasterIC/IC/CYPR/CYPRS06053/CYPRS06053-1.pdf?hkey=EF798316E3902B6ED9A73243A3159BB0

It needs more work.

The chip has three CS pins and need to take care separately.

You can build a adapter to take care those pins based on chip 2716 EPROM with 12V VPP.
