Re: Apple ][ and Mac question

  Older NEC Multisync monitors (I think the 3FG/4FG models) could go from 
PAL scan up to SVGA - I used one with a simple monitor switch between an 
Amiga 500 and a PC, I just had to build an adapter cable from Amiga and 
normal DB15 PC connector for the switch. The monitor would "click" when 
switching scan circuits. A damn fine monitor it was.
