Due to eye strain from many hours of coding I find the need to switch to an
amber monitor. I have a brand semi-new Magnavox monitor that I use on the
PC clone but I would prefer to code directly on my Amiga. So I would like
to know if it is possible to hook a TTL level digital video monitor to an
Amiga 1000 and have it work properly? If it is possible then I would
appreciate the specifics on how this can be done.
The Magnavox has a 6 Pin Din plug to the monitor and a 9 Pin "D" to the
Monochrome Adapter Card on the PC clone:

Thanks in advance for any information on this question.

(3-4 months ago) This is a real shame because a device like this would be a Most Excellent second-monitor option, since almost everything I do is interlaced. I'm sure there's a large demand for such a thing. Why don't we bother the company for details (I can't make non-collect long-distance calls here, but someone should try their Technical Support number: 604 524-1125 Let's see this product in reality!!

This is a repost because it seems we were disconnected from Usenet for
a few days and I don't believe this ever made it out.

$99 for the interface plus another $99 for a TTL monochrome
monitor, you might as well buy a NEC MultiSync GS, and have less hassles.
But then, if you already have a TTL monitor, or that you're really tight
financially... 8(

(3-4 months ago) As far as I know of the product does exist. But then it isn't much. It doesn't de-interlace the signal going to the monitor it uses a TTL monitor which has long persistence phosphors which makes the flicker much less noticeable. However, it requires a specific monitor, a Commdore 1090 I believe (not included in the price), which you then have to go inside and hack so that it can be driven by a RGB analog type signal rather than by the digital values. Other than that, it is mostly a cable. Any amiga has digital RGBI coming out the back so you can hook up a TTL monitor directly but getting something that produces readable output for your typical 4 level monitor is a little iffy. I also had to go inside the monitor and adjust it to get reasonable height since the scan rates differ between normal TTL and the Amiga's CGA rates. Be forewarned, the signal voltages inside a video monitor are nothing to mess with if you aren't pretty savvy about electronics and servicing. David Albrecht
