- I've got the documentation (schematics and program) for the
- last of the arcade spacewars games, which was still vector based
- but used a regular TV tube for the display and had angle
- correction circuitry added for the wide deflection angle found in
- TV kinescopes as opposed to an oscilloscopes' CRT. If anyone is
- interested, I'll gladly copy it all off for ya in trade for
- keeping me posted as to what you do with the info...
