Ehm, well, if I had been correct, I wouldn't have said 'PC', since a
LGP-30 is a 'PC', too, by the terms of its time ;-))
But IBM PC does not say anything about a specific graphics card.
You said 'any PC'. OK, I will read 'PC' to mean 'IBM PC compatible
computer'. thus rulling out things like LGP-30s, PDP8s, etc. You did
not, however, specify a video card. I therefore assumed that any
PC-compatible video card would work, and the original IBM MDA card is
one such.
In other words, a 5150 with an MDA card is a member of the set of 'any
PCs'

Well, perhaps then _simple_ graphics, i.e. stuff created using the
line/box-draw characters in the MDA card.
I distinctly remember enjoying playing a very graphical version of
Othello on my dad's first-generation (PC-1) IBM machine with only an MDA
card.
I probably still have it somewhere. There are a lot of .BAS programs
included with the first versions of PC-DOS.
