tinymicro-mos6502-kansas-lava

=============================

A tiny microcomputer built around the MOS 6502 microprocessor.

It is inspired by the emulator at http://www.6502asm.com/.

Memory Layout

-------------

* `$0000 - $3FFF`: 16K of RAM

* `$0200 - $0600`: 1K video framebuffer

* `$E000 - $FFFF`: 8K of ROM

Video Output

------------

The 1K of video framebuffer is connected to a 800x600 VGA signal generator,

at a resolution of 32x32 in row-major order. Only the low 4 bits are used,

via the 6502asm.com palette.

Software Dependencies

---------------------

* Kansas Lava 0.2.4.1, from [my fork](http://github.com/gergoerdi/kansas-lava)

* [Shake build rules for Kansas Lava](http://github.com/gergoerdi/kansas-lava-shake)

* [MOS6502-kansas-lava](http://github.com/gergoerdi/mos6502-kansas-lava)
