Yeah, that is why I keep it around.  It is fun to run up a Tahoe or
an Ultrix32m or a NetBSD-1.2 on it and watch it fly.  It is like a
comfy end table, that heats the shack, in winter, and really ain't
all that slow on those early suites.  A kernel compile in Tahoe
is 15 minutes (must be a gcc feature of later times that takes the
24+ hours in NetBSD)!

The 650 and 660 cpus are in my other machines.  The reason I keep the
630 cpu around is that it runs the TK50s with fewer errors than on the
faster cpu's, in my hands....timing issues that still need some bit of
twiddling, methinks.

/begin{beggingmode}
   But, if anyone has a spare Qbus scsi controller about, that would
   rescue the machine considerably, from esdi hell.
/end{beggingmode}

48 seconds to compile kernel.... nah, that must be a pipe dream!
I blinked!  Are we done yet?
