VGA adapters for A500? Feasible, desireable?

As mentioned you can use any external scan doubler/flicker fixer on the A500.  There's also the ICD Flicker Free Video 2 which is internal for the 500, 1000, and 2000.  ICD still has them listed on their website for sale.

Note: if still available new, they're prohibitively expensive at $180.  I'd suggest an external model that you can move from computer to comptuer as needed.

A standard upscan converter works, but it doesn't offer the visual quality that a real scan doubler/flicker fixer does.  Also, since the A500 doesn't have composite or S-video out, which the upscan converters normally use, you'd need additional hardware.
