|Atari Mega STE |
Long time after my first STF, I had a STE and then this MegaSTE!
| This configuration comes with a graphic card, originaly designed for TT, that I had to adapt the drivers to make them run on a 68000. |
It is an AlberTT that plugs into the VME slot.
It offers the huge resolution of 1024x768 in 16 colors!
This MegaSTE also has a MC68882 coprocessor to speed up scientific calculations.

|In this version 1.2, it only has one resolution: |
The card has 12 RAM ICs with 32KB each, for a total of 393 216 bytes. For the largest mode, 1024x768x4 bits = 393 216 bytes, everything is used!
| The drivers|
In the archive you'll find three folders:
|The card having a vga 9 pins output, an adapter is requiered to connect a standard VGA monitor. |
The adapter is a vga 9 pins male to 15 pins female.
|What you need: |
Open the MegaSTE and look for the FPU slot facing the power bloc, next to the VME flat connectors.
There you find:
|As my mother board has no jumper, I had to remove completly the board to access a resistor linking two pins from the GAL slot. . |
Just cut the pins to remove the resistor!
|Reinstall the motherboard and fit the FPU and the GAL in their own slots taking care of the orientation. |
Have a look below to see the performances when using FPU routines that I includedin my FORTH language.
|On the AlberTT card, color animations can be larger than 320x200, this one is in 640x400.||The monochrom FLM can be displayed in the color mode with a special routine.|
|I adapted my FORTH to detect and use the FPU MC68881/2. If no FPU is detected, then my old maths routines are used. Motorola made this coprocessor to bring floating point instructions for arithmetic, trigonometry and exponentials. |

|Written by Ronald Andersson from my own programs Color_TT and Color_MSTE, here is COLORTOS! |
It brings color icons and 3D effects on the windows elements to your desktop. Why using ColorTOS more than my work:
Watch my desktop!
Note the3D effect on the button and window's bars, note also the color icons on the destop!
