Subject: Re: Industrial VAX 630 info wanted...
Well, I hooked my VT420 (9600.8.N.1) to the VAX, and got no
reaction on
the terminal. The LED diplay on the CPU card started at F, then flipped
A, and sat there.
On the CPU card, there are two switches, and I don't know
what they do.
I've tried different switch combinations, to no avail...
I'm sure 'a' is either 'looking for boot device' or 'language
selection' but
I could be wrong. My manual's in the garage.

On the left side is a 2 position switch, upper position has a dot
inside a circle, and the lower position has the dot above the circle.
That's the setting it came at. There is also a triangle, pointed down,
inside a circle immediatley below the switch.
On the right is a 3 position rotary switch.1st position is a little
face type of character, second is an arrow pointing right (this is
selected), and the third is a circle with a T inside of it. There is an
arrowhead on the circle, makes me think it's a looping test setting?
The circle-and-dot is the halt enable switch; when the dot's in the circle
you can halt the CPU with BREAK on the keyboard and the usual CTRL-P. The
other switch is a mode switch IIRC, the 'face' forces a language select and
the arrow is 'run'. If I get a chance today I'll dig the book out.
cheers
