Subject: Re: BBC to VGA monitor?

Aha! Another sad Sun employee with an interest in BBC micros!

I don't have a colour monitor at all. For fun (?) I have used
my BBC Master 128 via my SunVideo card ... but perhaps my Sun
CPU cycles would be better spent on emulation!

p.s. if anyone has a CUB monitor they don't want, please drop
me a line.
