I was wondering….is there any reasonable way to connect a TTL monochrome monitor to the Amiga? They generally have a long persistance and would be an inexpensive alternative to a FlickerFixer and a 31.5 mHz or autosynch type color monitor. I use interlace for DTP and $1000 is pretty steep for getting rid of flicker. Does the Amiga only make digital RGB, analog RGB and composite outputs? I know that long persistance color monitors exist but they are also big bucks and would be less than optimum for animations etc. I have a TTL monochrome just sitting around.
