[comp.sys.sun] Microsecond clock for Sun 3/50 and 3/60 available

melvin@ucbvax.berkeley.edu (Steve Melvin) (05/26/89)

A small PC board has been developed which plugs into Sun 3/50 and 3/60
motherboards adding a flexible microsecond resolution timer.  It takes a
constant 25 microseconds to generate a time stamp on a 3/50.  It plugs
into the encryption chip socket and looks like an encryption chip to the
hardware.  No hardware modifications are necessary but a new device driver
and system call need to be installed. For more information send mail to:
