Bear in mind I’m an old DEC head and have been since the early 80s ;) Though I
HAVE seen customers get RJ11 cables jammed in MMJ ports before, because ’they
look alike’.
Both of you missed my sentence where I said ‘It doesn’t matter what position I
have S3 in’, and IIRC even with S3 set to graphics you would still get a dead
sergeant on a VT once init had completed, you just wouldn’t see POST.
Anyway, I’ll hook up a VT today at some point and see if anything happens.
Cheers
