My VS4000-60 has a DALLAS chip that is either dead or not working very
well: it will not remember settings at all. It boots fine using a VT420
and it also boots fine with a monitor/keyboard connected.
Do you get *any* output on the console at all?
The easiest thing to try would be a known good VT terminal, then you
don't have to worry about the H8571-? being the correct "-?" for your
config (ISTR that there are a number of variants, each subtly different).
