From memory a garbage screen is normal when you switch
on? Don't you have
to press a key to clear? <Break> comes to mind but
I'd have to check.

Vintage Computer Buds,
I dug out some cables and hooked up my Challenger 1P to my TV. Instead
of hooking the video directly to the TV like I did before, I hooked it
through a Magnavox Modulator that rebroadcasted the video signal on
channel three. This worked for some reason. Well, kind of. The URL is
to a photo of what displayed on the TV. It wasn't too easy to read,
but it is clearly some kind of ASCII character dump. No clue what's
going on. Do I need to invest in a proper old-style modulator like
they used on the Atari 2600 that will "split" the A/V signal from a
single RCA cable and then put it on channel 3? Per the website, [

looks to be the case...
Here's the output I do have. What the heck is my machine doing?
