RCA 1861, NTSC and a DEC VR-201

What do those things have in common? Apparently not much. I was attempting to lighten my load for the VCF and I ran across a small problem. I have this cable I made to use a VR201 with an Amiga. It works. I even tested it tonight to eliminate sources of failure. When I try to hook a COSMAC VIP up to it, I get nothing. The numbers (from the RCA 1861 spec sheets) look like this: NTSC 1861 @ 1.76064 Mhz 1861 @ 1.764000 Mhz 1861 @ 3.579545/2 -------- ------------------ ------------------- ----------------- Line 15750 Hz 15720 Hz 15750 Hz 15980 Hz Field 60 Hz 60 Hz 60.11 Hz 60.99 Hz The xtal in the VIP is 3.521280 Mhz (2 x 1.76064 Mhz). It seems that the VR201 is sensitive to a 30 Hz difference in the horizontal freq. Barring the chance that I can locate a 3.528 Mhz xtal before the VCF, am I hosed here? I had hoped on using either my VR201 or one brought to the show by a kind soul. As it stands now, I'll have to hope for a kind soul to help me with a standard NTSC monitor (I've just tested the VIP with a more ordinary Commodore 1084S). Can any video guru's shed any light on my dilemma? Is the VR201 that sensitive? Is there a way to get around this? Thanks, -ethan ===== Infinet has been sold. The domain is going away in February.
