Plate files for NCR-80, MK870?

Hi everyone,

It is possible to build certain budget customs like the MK870 with POM, PC, and other plates. You can order aftermarket plates from AliExpress.

However, I wonder if it’s possible to go into more detail. Like, what if certain plate services could create custom plates for these boards?

You would need plate files, and I’m not sure they exist. Does anyone know of plate files for NCR-80 + MK870, or should I just order from AliExpress?
