Hello there,

Anybody with a real computer of the Tandy-1000 series can confirm if this kind of characters appear when the computers are reset via CTRL+ALT+DEL during POST?

If I reset from a text mode screen like this...:

I get this during POST:

The attachment 20251222_170554-screen.png is no longer available

And if I reset from a graphical screen like this...:

The attachment 20251222_171329-screen.png is no longer available

I get this during POST:

The attachment 20251222_171340-screen.png is no longer available

Is that how the Tandy 1000 series really work? I am seeing this on the opensource PCXT/Tandy 1000 core on MiSTer and trying to confirm because the core author is trying to improve the Tandy implementation, so I need to confirm whether this is the actual behavior of an actual Tandy 1000, or this is a bug in the implementation.

Thanks!!
