[rescue] Pinouts of the 3/80 P4 connector ?

[Romain Dolbeau]

Hello,

I don't remember ever seeing this one documented anywhere, but maybe
someone here knows!

I'm looking for the pinouts of the P4 connector in the 3/80, which is
documented as different from the one in the 3/60 and 4/ systems (not
that I've found the pinouts for those either). Physically it's easy,
it's a 3x32 pins DIN 41612 connector, extremely common.

And also, how does (if it does) the system detect the framebuffer on
said P4 device (SBus is easy with OpenBoot/OPenFirmware, not sure what
the 3/80 does, haven't tried booting mine n 20 years and the PSU seems
long dead, idly wondering how to resurrect it with a modern display).

Thanks & cordially,
