This is it. This is what it was all for. All the penposting. The hundreds of dollars of irresponsible eBay purchases.

For this moment.

And it was all worth it.

@gloriouscow Love following along as your travel down the lightpen rabbit hole. I had a McPen for the Commodore when I was young. It literally felt like the future to touch it to the screen and make things happen. Wasn't a lot of software that used it though. It came with a disk and some programs, notably one that copied files between disks but pointing at them from a list. Super cool.

@paulrickards Finding an actual, singular decent application that isn't just a toy or a slapped-on feature for the light pen is deeply satisfying. And the thing is I basically stumbled across it at the last minute.

I wanted to do a video on the light pen, but honestly was feeling a little bad about it because running through a calibration utility is not exactly the most exciting thing.

@gloriouscow True, but calibration is part of using one and worthy of explanation. Imagine if we had to recalibrate touch screens today.

In theory, drawing applications are a natural extension. In practice, it was extremely frustrating.

@paulrickards Even without a light pen card, this is actually surprisingly usable. Freehand painting sucks, but since this program lets me drag things around to fine tune placement, I can get about as good a result as you're gonna get out of a 320x200 graphic anyway.

It sure as shit beats MicroGrafx's method of nudging stuff around with tiny little arrows

@gloriouscow As far as C64 lightpen apps go, there is PlatoTerm from a few years ago. Notably, it supported all sorts of input devices, including a lightpen!
@paulrickards is this yours? may I use this photo?

@gloriouscow Yes and yes.

BTW, that's not the McPen in the picture. That's another type, a little fancier actually. It had a switch in the tip so you could tap the screen to push the "fire" button of the joystick port, presumably. The McPen had no such function.

@paulrickards Yeah, I have seen both types. The industry definitely settled on tip switches.

lol, the "industry". After the 80's it was pretty much just FTG .

FTG did eventually add a second button on the side for right-clicking.

The C64 supports two light pen buttons, my Inkwell pen has two, neither on the tip!

@paulrickards

by all accounts i pretty much have one example of every light pen card FTG made. They switched to external light pen interfaces at some point , but for some reason those are always listed for $200 or more without even including the pen so frack that
