Re: Anyone ever attach a mono LCD to a PET?

Hi Ethan,
 
I have looked for mono lcd screens on ebay for exactly the same purpose and haven't had any luck. the occasional one would be listed but at ridiculous prices. I think you'd be better off with a color panel. VGA LCD monitors are quite cheap but these days it's hard to find one that syncs down low enough. I have an NEC 1550M unit that syncs down to 15kHz and I was hoping to try to hook that up to the pet somehow. I think you need to adjust the voltage levels though.
 
 The other option is to go with a TV-type LCD unit that accepts composite, and just make a small adapter to convert the PET signals to composite. You can buy a small pre-made board on ebay for $25, but it's really just a single chip that should only cost a buck or so.
