I vaguely remember readong somewher ethat it might be possible to put some sort of termination sort of thing on the 23pin port to make the Toaster happy, and use the user interface software via a cybergraphics or picasso96 suported cards to an SVGA monitor.
I'd imagine you could use a flickerfixer/scandoubler as well, as it would effectively terminate whatever signals go through te 23pin port just as an RGB monitor would.
Hopefully someday I'll have time to play with my toaster, which I'd prefer to use with SVGA via PicassoIV instead of finding space for a 1084 on my desk. It's amazing how cheap toasters are on Ebay these days.
