PC-3000 Forum

Hello everyone,

On this 2060-810035-001 pcb the rom is encrypted and the component ref is : IS25WQ040.
For reading rom externally and decrypt it, I'm using a CH341A programmer or the RUS V5000 but it doesn't recognize this Rom model.
Does someone could give me a bios programmer which is working with this component?

Best regards

François

Rom is not encrypted. Revelprog reads them easily.

+1 for Revelprog

You can use CH341 programmer with a good software e.g. NEO Programmer but you also need the tool to power the ROM at 1.8V which is an optional module usually not provided with the various CH341 s available on ebay

Most probably if you find the 1.8V adapter, you are already done

if not, together with the 1.8V adapter, search for NEO Programmer software
