Here’s a little demo that shows 16 digits per line, without venetian blinds, flicker, or ‘zig’. The temp RAM requirement is significant but not unreasonable (slightly under 32 bytes) and the code/tables are large but not huge (the demo is under 2K). The time to set up to display each line is significant but not outrageous (the demo shows eight lines of sixteen digits each); using another K or so worth of tables would cut setup time in half.

To use this demo, move the cursor with the joystick and press fire to change a digit. All 128 digits may be set independently.http://www.atariage.com/forums/index.php?showtopic=79626
