What OS do you intend to run on it ? Vintage SunOS 4.x or some more
recent NetBSD ?

A good solution might be to share that on GiHub or similar to foster
collaboration.
I haven't tried to recreate a system, but I've looked at the P4
connector to see if I could port my '030 FPGA-base expansion design
[1] to a 3/80 or 3/60. Unfortunately I don't have a 3/60 and my 3/80
motherboard is dead for now so that stalled :-( But a recreated 3/60
would be of interest to me for that reason. Maybe help where I can
(time permitting!).

Cordially,

Romain
