The plotting thickens

INSUBCONTINENT EXCLUSIVE:
It the late 1970s and pilot fish is working for a small company that produces custom solutions involving computer hardware, software or both
A large customer wants a pair of drafting machines — pen plotters that can produce large-scale physical engineering drawings from CAD
systems.And fish company comes through, integrating the plotters with DEC PDP-11 computers, which had a pair of DEC RX-01 8-inch floppy disk
drives to import and export the CAD data.The flatbed plotters measured about 4 by 10 feet,and the huge sheets of BoPET polyester film that
are used for the drawings rather than paper are held in place by tiny holes in the flatbed that lead to a vacuum chamber, like an air hockey
table running in reverse.
