I just bought an expensive ATI Mach32 for my Mega STE... please stop me

Just uploaded my findings on how to program the ET4000 VGA card on Atari ST (code).

I bought an ET4000/AX VGA card for Mega STE this summer.

The Mega ST, Mega STE and TT have expansion connectors to allow use of such cards. The main cards available at the time were NOVA and CrazyDots, but mine is a PC ISA card plugged on the VME port through an adapter.

Here's the card working at 1024x576, 256 colors:

And I tried to program it directly to check the usability and performance.

Well, it's not very good. Accessing the framebuffer is ~65% slower than accessing the main ST RAM.

So far I don't know if it's because of the VME bus or the ISA card.

Here's a pure blitter fill at maximum speed, 1024x576x8b

And here's the card using 24 bits mode (true color) at 640x480 and 320x240.

I added the 320x240 mode with a tool that allows to create your own resolutions.
