[Simh] Setting DECSERVER 90L to factory defaults

[Robert Thomas]

Rich,

This procedure doesn't re-establish the factory defaults.  It is one of
those flawed designs that occasionally slip through to cut costs with
unexpected consequences.  The 90L and 90L+ are the only Decservers with no
reset to factory defaults capability.  The follow on product, the 90TL has a
reset button.

Sincerely,
Robert F. Thomas

Pages 40-41 in the PDF (pages 4-13 and 4-14 of the DECserver 90L user
manual).

You need physical access to the 90L, because you have to power cycle it to
change from Authorized (uses passwords) to not.
