Do you have any idea how many PDP-11's were used by NASA for things
like controlling deep space probes and putting men on the moon?  A BBS
is a vewry low demand task and could easily be handled by the smallest
of the LSI-11 family.

Heathkit h11 lsi11 macheans? Witch was a hobyist pdp11 for those that are
unfamiliar with the hearhkits
