 Well, how do, Roy?

The latest on the bench was a NEC. Seemed easy enough to get into, but the
vert. retrace remained misplaced. Most of the tweaking on the colour balance
didn't seem to take hold either. I'm starting to think some of those controls
need to have a service switch set before they come online.

I bought a NTSC generator at auction, but have yet to plug an AC cable into it.
Of course it doesn't do much for a 'puter monitor with its composite output.

Good thinking with the Linux box, no doubt! You'd want a VESA capable card for
its versatility, no?

As you can imagine, stressing the retraces are not a consideration for these
old piles. The shop could use some excitement/light shows. <G>
