VI65 text editor

A VI implementation for 6502 machines.

This is the "manual" of the multi platform VI65 0.2 editor.

The editor (and the documentation) is far from finished, and there are a lots of bugs. Maybe the next version will be better ;)

Supported platforms:

Commodore 64, 128, 16, Plus 4, VIC20 (expanded), PET 40/80. Atari 8bit, Apple II. There's a plugin version for the IDE64 filemanager too.

Supported text modes:

C64 - 40/53/64/80x25 (VDC 80x25 on C128)
C128 - 40/53/64/80x25, VDC 80x25
+4 - 40x25, 53/64/80x23
C16 - 40x25
VIC20 - 22x23, 26/35/40x22
PET - 40/80x25
ATARI - 40/53/64/80x24
APPLE II - 40/46/56/80x24

Some text modes use custom 4x8, 5x8 and 6x8 charsets on graphic screen.

Limitations:

251 characters in a line
65535 lines of text (memory runs out faster...)
