HP41 display specification?
Was the protocol that the hp41 CPU uses to communicate with the display ever documented/reverse-engineered?

I have a couple of 41s (one fullnut, one halfnut) with broken LCDs. It would be fun to build an external display using, say, B7971 nixie tubes Smile

The spec for the display driver is on the Museum DVD.
