We have an old LSI-11 running V7. Uptime is 49 days. I don't recall the
last time it went down but I think it was because of a power failure. Before
that the last reboot was in March when we replaced the flakey hard drive.

I have no intention of ever getting a SV system if I can at all avoid it. I
have too much software that Bell won't run because they used PWB as the basis
for SIII instead of V7 (the last true UNIX). 4.2 is exceptionally compatible
with V7... and the 4.2 system next door has proven itself reliable.
