[Simh] Setting DECSERVER 90L to factory defaults

[Robert Thomas]

We have the physical device.  With respect to the first suggestion to find
someplace where there might have been a reset button, we have removed the
plastic covers and there is nothing visible.

On Decserver-90TL, there is a reset button accessible from the front.  Such
does not exist on Decserver-90L.

The comment with respect to the power/power on sequence is to allow for the
authorize password change.  If one doesn't cycle power immediately after
changing the password, the change is ignored.

Given the simplicity of the device, we never enabled authorization or
passwords. We have some Decserver-200's which are much more complex devices
that have reset buttons as well MOP operations, i.e. download/upload of
settings, ETC. 

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.
