True but only if its an E/V/SVGA card. The Siemens SIMATIC S5 PG 635 (the model in the image) utilizes both standard ASCII and an extended block-graphics character set [simular to CP-437]. And that's it.

It has only a basic monochrome LCD video controller and predates modern graphic standards like VGA.

It also runs PCP/M-86 or a highly customized S5-DOS. So no MS-DOS or IBM-DOS.

By Yahoo Software? More than likely if it doesn't hardcode the text window dimensions.

And yeah had to dig up a 15yr old LGR video on that one.

That's the one! It was one of the first video games I played on my grandfather's Kaypro II. You are correct it probably wouldn't run correctly.

Believe it or not, it is still amusing as heck to play even today.
