Which original? the C64 or Atari. The important characteristic of
both is that both have multiple overlapping popup boxes. This
means that either you or a widget framework much keep track of
stacking order and how to restore what was hidden when a box goes
away or is moved down in the stacking order. I would not be
surprised if the Atari had at least a rudimentary widget
framework.

But when I try to print those characters, I get an error:

You have two separate problems with running in the windows
console.
<br>
<br>
1. The character issue. If you run a program to just print the
above from an Idle editor, so that the output is printed to the
Idle shell, there should be no problem.
<br>
>>> print('\u2556'*10)
<br>
╖╖╖╖╖╖╖╖╖╖
<br>
But characters are not your real issue.
<br>
<br>
2. The random access issue. The MS console in normal use is like a
serial printer or terminal. Once a line is printed, it cannot be
changed. I looked at the video and the program randomly accesses a
24 or 25 line x 80 column screen, overprinting existing characters
at will and reversing black on white versus white of black at
will. MSDOS screens recognized standard ANSI screen control codes
once the ANSI.SYS driver was installed, which was fairly normal.
But cmd.exe is actually a regression from MS-DOS in that it
apparently will not allow this. Or it is a hugh pain.
<br>
<br>
You could get a program that emulates a full-screen ANSI terminal,
and learn to use ANSI control codes. Or you could use a tkinter
(tk) Text widget. People have written at least serial terminal
emulators for Text, but I did not find a full-screen.
<br>
<br>
Using tkinter, I would try making each box a separate text box
placed in a frameand let tkinter worry about displaying them
correctly and detecting which box get a mouse click or
<enter> key.

I've never used the API from Python but random console access is
documented at
