Removed the program as it seriously looks like copyrighted software,
if uploading something please try to find some demo/freeware version
of the application/game.

It was present, but never worked because nothing used this mode.

> The problem is that the fonts seem to be missing.

They are writing directly to the graphics memory, but there wasn't
anything odd about this. Could be that they need some fonts to be
present in the ROM, not sure how this looked like on the Tandys.
The text that is not rendered from fonts (F1...) is displayed fine.

I gave it a go myself, being a old Tandy 1000TX owner, and I too got no fonts. There's no readable text anywhere. I'm using Personal Deskmate 2.

Does machine=tandy help? I'm guessing you're all using that setting already though...

yeah I used that option. The graphics are there but there's no text.
