I really thing the C-128 Video Mux is a pretty nifty product:

www.pyrofersprojects.com/blog/product/c129-video-mux/

Pyrofer , I was wondering what it would take to make something like this, but with these changes:

* NTSC
* HDMI out instead of SCART
* What does it take to change RGB output to scale up the 15hz for use on modern 50Hz+ monsters, without having to buy one of those upscalers (gonbes??)

NTSC is easy, you move one jumper and swap the crystal.
HDMI is easy, you buy a $25 SCART to HDMI adapter on ebay (the sort that works with Amigas) and connect this via the included SCART cable to the HDMI adapter.
If you don't want to use a Gonbes to get VGA etc you can get another scandoubler like the framemeister or OSSC. Other options include a multisync monitor (there is a list for Amiga users of VGA monitors that do 15khz) or run the 128 in VGA mode (it can just about convince some monitors to show a picture)

Do you have any of your c128 video mux boards available? I can't seem to find any contact info on your site and everything is marked out of stock. Thanks!

I am having some issues that are preventing assembly of parts, not the least of which being the death of my "new" reflow oven. I have parts to assemble here... Just keep checking I guess.
