Hello
In the mid 80ies i was at school in Sk?vde Sweden.
At that time that school had a PRIME 9955 system together with the
normal serial terminals and also a fair number of specialist CAD
workstations.
The CAD stations was used for MEDUSA and another Electronic CAD package
(we did PCB designs in that system.)
I have two questions (because of a foggy memory):
what was the maker of the work stations (or who could they be) ?
and
could someone name a number of pcb design programs for PrimOS ?
