Apple IIe Mid-Screen Mode Switch Test

For a more exciting example of this see the Double Double test. This was an earlier static test I made.

The "DOUBLE" Test


Actual Apple IIe platinum (output captured using capture card)	AppleWin 1.13.30.0	Mame 0.251 (apple2ee)

Notes: the mode switches are cycle-counted. It's using the Apple IIe method of getting VBLANK so this won't work on IIc/IIgs probably. It also won't work on II+ but then again the graphics modes wouldn't either unless you have some sort of weird graphics card.
