Good morning,

Has anyone run into a problem where you powered off/on a 420R and
the
system never produced console messages again nor does it boot to the
Forth OS? We have a system that did that
this morning and we wound up transferring the cards and disks to
another
system to recover. I looked at the service manual and the only thing
of
interest were two batteries in the system, one system board lithium,
the
other a lead-acid battery. Has anyone experienced the same symptoms?

Thanks,

E. Rudolph
