TWENEX /twe'neks/ n.
The TOPS-20 operating system by DEC
-- the second proprietary OS for the PDP-10 -- preferred by most
PDP-10 hackers over TOPS-10 (that is, by those who were not
ITS or WAITS partisans). TOPS-20 began in 1969 as Bolt,
Beranek & Newman's TENEX operating system using special paging
hardware. By the early 1970s, almost all of the systems on the
ARPANET ran TENEX. DEC purchased the rights to TENEX from BBN and
began work to make it their own. The first in-house code name for
the operating system was VIROS (VIRtual memory Operating System);
when customers started asking questions, the name was changed to
SNARK so DEC could truthfully deny that there was any project
called VIROS. When the name SNARK became known, the name was
briefly reversed to become KRANS; this was quickly abandoned when
someone objected that `krans' meant `funeral wreath' in Swedish
(though some Swedish speakers have since said it means simply
`wreath'; this part of the story may be apocryphal). Ultimately
DEC picked TOPS-20 as the name of the operating system, and it was
as TOPS-20 that it was marketed. The hacker community, mindful of
its origins, quickly dubbed it TWENEX (a contraction of `twenty
TENEX'), even though by this point very little of the original
TENEX code remained (analogously to the differences between AT&T V6
Unix and BSD). DEC people cringed when they heard "TWENEX", but
the term caught on nevertheless (the written abbreviation `20x'
was also used). TWENEX was successful and very popular; in fact,
there was a period in the early 1980s when it commanded as fervent
a culture of partisans as Unix or ITS -- but DEC's decision to
scrap all the internal rivals to the VAX architecture and its
relatively stodgy VMS OS killed the DEC-20 and put a sad end to
TWENEX's brief day in the sun. DEC attempted to convince TOPS-20
users to convert to VMS, but instead, by the late 1980s, most
of the TOPS-20 hackers had migrated to Unix.
