1.
I have an S-VHS TV and an Amiga 2000 with the old chip set.
Is it possible to connect the Ami through the S-VHS port of
the TV?
2.
Is the video signal from the video port always 31.5kHz with
the ECS installed?

There is only a Monochrome composite jack on th eback of a 2000. This might be sufficient to supply a monochrome image to a S-VHS monitor. For color images an NTSC/S-VHS encoder would have to be plugged into either the video slot or RGB port. Examine past issues of the various AMIGA periodicals for suitable products. 2. No, ECS is a superset of the original chip set - anything they can do we can do(unless Victor and I broke something and nobody told us about it :-) !!!). Basically ECS involves three things: 1.) programmability of timing registers that used to be hard-wired(horizontal total,start and end of blanking,etc.) 2.) creation of a SHRES pixel resolution(35nS) 3.) additional genlock support(border transparency control,color table and bitplane transparency,etc.) Using 2.0 preferences you can set horizontal scan rate to 15 or 31 KHz. For applications, horizontal and frame frequency are programmable over a large range of values.

It truly is a cheat since it loses the advance of S-VHS's better picture quality. >+----------------------------------------------------------------------------+ >| Dallas J.

This is basically a repost from last June: I had to make my own VI500-to-SVHS adapter by halving an SVHS-to-SVHS patch cord and connecting its wires to a pair of RCA Phono plugs. Here are the specs as determined from the patch-cord package and the schematics of my TV. It has worked for more than a year on my Amiga 500 with a (CMI?) VI-500 video adapter that has separate Chroma and Luminance phono jacks. S-VHS DIN plug RCA PHONO plugs (end view, mirror of socket) (side view) ..... .... .... .'' ``.
