I'm not sure how interesting this ancient DES chips business is for
most people on the list, but here's a follow-up. Patient readers will
be rewarded with a subversive Easter Egg from 1985.

I had a look in the SunOS 4.0 man page for des(4s) and found
something interesting. Apparently the Sun-2 could also be equipped
with a DES chip. It says:
CONFIG - SUN-2 SYSTEM
des0 at virtual ? csr 0xee1800
The DES chip that AMD produced, AmZ8068 (also known as Am9518), was
validated by NIST already in 1981, so a Sun-2 implementation would

The suspicion that it was never sold seems to be confirmed by the
following quote from a paper written by Peter Danzig and Steve Melvin
back in 1991 ("Microsecond Resolution Timing with Sun Workstations",
available at http://catarina.usc.edu/danzig/usec_tmr.ps.Z).
"The hardware of Sun 3 and 4 workstations supports a data
encryption chip (DES), but the federal government pressured
Sun to eliminate the DES chips from their products. For this
reason the DES chip's IC socket is empty in these workstations."
Now being curious, I went to the Sun 2 Multibus Rev R ROM that Matt
Fredette has posted on his Sun-2/120 emulator page

I doubt the line "Love your country, but never trust its government."
is intended to be spit out on the console. It appears someone at Sun
added a subliminal protest against the government to the Sun-2
