I have peaked.

@gloriouscow Now you need to make it chase the light pen!

[ravenluni@furry.engineer]

@gloriouscow And thats all done via the character ROM?

[gloriouscow@oldbytes.space]

@RavenLuni There's a little probe tap on the CURSOR pin of the 6845 to locate the cursor position, and a probe tab to the VSYNC pin on the back of the DE-9 connector. Everything else is via the font ROM socket.

[gloriouscow@oldbytes.space]

@jernej__s It's doable, but it will require a program unfortunately, it won't just work randomly in DOS as the light pen strobe latch has to be reset every frame which is not normally done.

[gloriouscow@oldbytes.space]

@jernej__s wait... i can just connect the pen to the glyphblaster directly...

@gloriouscow This craps all over modern computing and its deathly lack of whimsy
