Re: PSA: Clock drift and pkgin
I copied the running RA0.dsk file from my running SIMH build to an HD.img
file on a ZuluSCSI card - that booted successfully on a 4000/60. So I will
try booting it on a real uVAX-II tomorrow and see how the clock behaves.

However, I've noticed that no one seems to be reporting the large time drifts (minutes lost per hour) that I am seeing. I'd like to mention that -- IIRC -- I saw this on both my KA630 and the simh emulated KA630, so it could be something specific to the MicroVAX II and brethren.
