There is some low-profile scandoublers to DIY on aminet, too.
Just remember the resulting image is sooooo ugly you think you have destroyed something. I've tryed the "PIC" version once. Man, it stinks! The version with 3 transistors is a bit better, but still stinks... :roll:
Buy yourself a professional scandoubler, or a multisync monitor, or at least a TV with a SCART connector. Those options are far better to connect your Miggy to a screen.
