A few newbie AmigaDOS questions

[SamuraiCrow]

It sounds to me that you are trying to run PAL demos on NTSC which often doesn't work.  Also it sounds as if your TV is getting lumanance but no chromanence.  Are you using the RF modulator or the composite outputs?  If you are using the RF modulator try hooking up through the composite hookups (maybe though an old VCR if your TV doesn't have composite video).

I'm using the composite output. Its a euro amiga, set to "NTSC - High res 640x200", even workbench has no colors. Any thoughts as to why theres no color? I've tried a few tvs, direct and through a vcr. (its workbench 3.1)

Try to use the" rf" or the rgb port trough the scart input of your tv

theres no scart input on my tv

There could be a broken pin inside the A1200 that connects the chromanance to the composite output.  The logical diagnostics' next step would be to either connect your Amiga to an RGB analog monitor.  Since you've tried other TVs we know that the problem is in your Amiga so there wouldn't be any point in trying a different Amiga on your TV.  My suggestion would be to try to find a cheap monitor like a Commodore 1084S with the Amiga cabling, to find another A1200, or get one of those TV adapters for the A500 and use it on your A1200.  Sorry I didn't have better news.

Well interesting either way.. Its not just a problem that with NTSC mode not properly displaying ntsc color fields on european units? Perhaps attaching it through the RF modulator port could bypass this possible bad-pin problem? Would a attaching a multisync monitor via an amiga->vga adapter be a viable solution? Thanks for any advice regarding these.

When I used to use my A1200 on a TV set I used the RF modulator. The
strange thing is, my TV can't take NTSC (only 60Hz PAL) so when using
the NTSC monitor drivers AmigaOS doesn't seem to be using the NTSC
broadcast colour mode on European machines, just 60Hz PAL.

There is no monitor driver in Workbench for 60Hz PAL strangely enough.

What you appear to have happening is a PAL Amiga on an NTSC TV... or
an NTSC Amiga on a PAL TV.

The only way to avoid this is not by using the RF or composite outputs
but using the Video output pins. This will bypass colour encoding
PAL/NTSC) and give you crisp, region free RGB.

Strange and complicated I know.

Hum,
i suppose you could check by holding down the two mouse buttons and choosing `display options`....
