68000 dazzler implementation

[mattp]

 Finally - got the GD2 library working on my 68k implementation on an Arty A7-35t (https://github.com/mattuna15/zed-68k/tree/arty-gd)

Most changes were to use my own SPI hardware, remove EEPROM code, and swap to Big Endian integers.

So if you're interested in the changes you need to make to get the library working on different hardware or want to try a different approach to the hardware take a look:

github.com/mattuna15/merlin-software/tree/master/gd2-lib

Next steps are to get the controls and sdcard up and running.

My Basic and Assembler re-implementation of the GD library is working nicely. I have lines and points and am reusing the GD library random function. Will be starting bitmaps next. If anyone fancies a look here is a basic implementation of a random starfield. Nice and simple to begin with.

First binary release here. Can just be uploaded onto an Arty/Gameduino combo to be working OOB

Finished developing an FPU for this, I've tested it using the framebuffer sample from James. The mandelbrot looks great in HD

Nice graphic from assembly language,

I haven't seen the 68000 used in a while, I used to repair Amiga 500's Atari ST's and Sega Mega Drives, having to de-solder them in Mega Drives's and Atari's.

There are not many people on this forum, hopefully it will grow with popularity of the Dazzler.
