Thank you very much for the warm welcome and the offer to blow the PROM's! Fingers crossed.

My 2111 chips arrived today - when I looked I had only one in my electronics collection (hoard from attic), which was not MM. Also didn't have most of the other 74 series either despite a fair range...

I did however have some offcuts of connectors including a single sided 15way that if I miss Pin 1 (as 2 is also 0v) will work for the Keyboard programmer... by luck Pin six was the Keyway which I don't need connected...

I will reach out if any further bits are needed.
