is dated almost exactly one month before DEC announced
the PDP-8 and I am sure targets the same markets DEC did. You just wonder if IBM had spies
in DEC, or more likely they both spotted a marketing opportunity.
The latter. Every company in the world seems to have explored the
minicomputer market in the 1960s.
Also, IBM was already in the minicomputer market with the 1620 from a
few years before. That machine clearly was getting outclassed by the
mid-1960s, and needed replacing.
