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: danzig@ucbarpa.Berkeley.EDU ...!ucbvax!danzig
