Hacking a VGA port onto the SE mobo

The SE doesn't use VGA signalling. FWI Seem To Recall, it should be something like an old 15Khz signal of some sort. Maybe an old multi-sync or other sub-VGA capable monitor might be able to sync to it. Otherwise you'll need what in the old Amiga world were "scan-doublers". They took that 15.xKHz and doubled the frequency to 31.5KHz to use a basic VGA screen. I never had a doubler, so I just bought an NEC MultiSync 3D for my old A2000. It could do some low frequency video modes.

FWI Seem To Recall, it should be something like an old 15Khz signal of some sort.

I don't recall the exact number, but it's actually around 23Khz. Roughly the same as the old IBM "EGA" standard.

They used to sell adapters so tap out the signal so it could be displayed on suitable fixed or multisync *digital* monitors:

They even sold a matching 12" monitor.

Note that VGA is *analog*, although it would be fairly trivial to convert the output to something that works, considering there's only black and white, no greys. However, also note the sync rate is well below what most modern multisync monitors will sync with, and that's going to include most (every?) VGA->LCD controller board.

Good luck.

I wonder...

The resolution is what, 512 x three hundred-something? I wonder if there are any monochrome graphic LCDs that would be fast enough. You'd have to design an interface, perhaps with a PIC or Scenix µcontroller to do the conversions from analog to serial digital. 23kHz sounds doable - the PIC 18s run at 40MHz.

(By graphic LCD I mean the small panels that electronics manufacturers and hobbyists use as device interfaces, not a VGA/Powerbook/other holy grail LCD)
