Rotatable cabs and scan direction

Post by CMPXCHG8B »

So I'm remotely pondering the possibility of purchasing a cabinet. By this, I mean I'm eyeing the possibility through a telescope located on a ship several miles off shore. So I'm not even sure I'm serious about it yet.

However, I do have one question.

With easily rotatable monitor cabinets (like the Egret II), when you pivot the monitor- do you also flip the tube deflectors then somehow tell the PCB that you've done so (either via jumper or switch), so that it can re-sync the monitor properly?

In a nutshell, I want to know how these monitors scan, and if that scanning changes to reflect the new orientation or not. For example, in yoko mode- the tube might scan from left to right, then down a line to repeat. If you turn the monitor 90* (tate mode), I'm trying to figure out if that changes how the monitor scans- if it now scans from bottom to top, then right a line and repeats. From your point of view, this would therefore mean that the same monitor in tate mode was scanning in the same direction (from your POV, that would mean from left to right, then down a line).

In other words, does the monitor scan in the same direction relative to the cabinet regardless of the orientation?

And if this is NOT true...

Does this imply that non-rotatable native tate mode cabinets have the benefit of scanning left-to-right, top-to-bottom whereas their hybrid brethren are locked to scanning from left-to-right, top-to-bottom in yoko mode (which would become top-to-bottom, then right-to-left in tate mode)?

Think of how a CRT TV scans. Now put it on its side to rotate it. Your horizontal game now plays in the wrong orientation.

A cabinet is the same.

Yup, lol. There is no trickery involved. It still scans the same way the screen is just on it's side.
