Isn't the video system very similar to that in the
VT100 terminal?
I have no idea. but from wild oberservation of its design... I
would
think that would be the case. as it is using a Vt100/Vt102 chassis.>
In which case, pull the cover and look at the little
PCB on the side of
the metal chassis behind the CRT. One of the presets on that board is
marked 'Vlin' or 'Vertical Linearity' or something like that (there are
at least 3 versions of the VT100 video board -- the 2 I've seen 'in the
flesh' and the one that's described in the printset I have). Try tweaking
that slightly.
Ok, now a question (not trying to be dumb) but HOW do I remove
this cover? from what I can see, the cover is not attached with screws but
rather some plastic type of clips.
Safety Warning : There are high voltages of a few hundred volts on that
PCB. So take great care when doing the adjustment. Use an insulated
screwdriver and don't touch anything you shouldn't.
Several Kilovolts to
be exact. so about 9.5x10^3 electron volts.
(think thats bad,, try working on a IBM 8513 with an UNINSULATED
screwdriver on a metal chair... OW! Precaution taken with expirence.
