Like the


Mentec, they have the license and make cpu/systems to go with the OS.
Some are quite fast compared the the 1978 gold standard (PDP-11/70).

or 11/83 series machines making the effort somewhat moot.

People have done PDP-8s for "lab projects" for years and at least one was
packed in to two arrays (cpu, memory and IO!) on a board small enough
to barely hide a 3.5" drive. The problem is PDP-8 is not a rom friendly
design from the start. PDP-11 is better there but much of the stuff
out there wants for RAM, excluding the unique code for the Falcon
and later class SBCs.
