The Z80's secret feature discovered after 40 years!

[ComSoft6128]

Mmm...

From Andy Hu's YT description:

"Edit: this video is the third release! I managed to iron out all problems in the second one, which includes:
1, CRT noise everywhere
2, intro video footages are not muted (you can hear computer noise over the music)
3, 0:55 the (absolutely terrible) B-roll is not muted (You can hear me watching a video about the Mindset computer in the background... I thought it was fine since I could just mute that, obviously I did not...)
4, 1:56 my voice is strangely 'doubled' making me sound like the Borg Queen (this does not happen at all when I'm editing the video! In my editing software the two vioces just overlap entirely and become louder)
5, 2:13 that B-roll (and the horrible CRT noise) is not muted
6, 2:45 a weird 'ding' caused by speeding up the video to hide a long blank
7, music is still too loud, but my editing machine probably have a voice enhance feature enabled somewhere too. This problem is much less pronounced on it (and maybe some other computers but probably not all).

Using a PlayCity and the SF2 ROM banking this all can be done already on CPC.

I saw this video on YouTube. It's pure clickbait. The Z80 doesn't and never did have a "protected" mode. The video does show how you can add some hardware and write an OS, so that a kind of protected mode can be simulated. But, without bank switching, you can only address 64k, so why bother?

It's pure clickbait.

Yes, and he had good luck. Usually his videos have around 1000 clicks or less. This one now has more than half a million...

He does the buzz only with a catchy title. Add some boobs and it will reach a million.

So, that's how I should get a million views!😂😂😂😂

It's not that easy As soon as you add too much boobs (already a little bit could be enough) to your thumbnail they will cancel advertisement...
And without ads Youtube isn't motivated to make your video popular.

There's always a catch...😁😁

[GUNHED]

A Catch 22!
