Hmm... Sam users are not alone in this how-do-I-connect-a-monitor problem. Atari ST and Amiga users have the same problem (well, older Amigas certainly do - don't know about newer ones), and so my guess is that a good place to start would be to look in an Amiga magazine. Every time I pick up an Amiga mag there seem to be a plethora of adapters to connect PC equipment and I guess there are PAL-to-VGA adapters advertised there. The problem might be if they are somehow Amiga specific.
Theoretically a SAM-to-VGA adapter wouldn't be tricky - all we need is some sort of RAM into which we feed one horizontal scan line from the SAM (and since the sam has its digital outputs on the euroconnector we don't even need to bother with digital-to-analogue converters) and simultaneously read out the previously stored line twice over and at twice the frequency of the incoming line. That'd give an output at 31.2KHz horizontal and 50Hz vertical, which *most* monitors should be able to cope with (though it is pushing at the lower limits). Anyone feeling brave?! Andy
