Message-ID: <19649@gryphon.COM> Date: 9 Sep 89 02:40:16 GMT Sender: root@gryphon.COM Organization: People-Net [pnet02], Redondo Beach, CA. Lines: 11 The common solution the the 6522 VIA is to delay one of the 'phases'. It's been a long time and my memory doesn't recall whether it's phase 1 or phase 2 clock signal. Usinge a D-type flip-flop clocked with the 7meg clock will delay this signal by about 140 nanoseconds, which is about right.
