Just wrote up a bit about an Allied Leisure Pong clone board from 1973 I got running. It holds many surprises and challenges!

Just put up my first repository on Github; this one is for the #ttllogic TTL-based video board as outlined by David L Heiserman in his 1978 book How to Design and Build Your Own Custom TV Games. I hope to be able to get some more of the game build up on there soon as well! But now maybe more weirdos will attempt some builds with it instead of it being just me?

Some fun pictures of my #ttllogic video game builds from the #makerfaire in Rochester!

Lord, I forgot what an unholy mess the Stormtrooper Attack build is #discretelogic #ttllogic #diyelectronics

It still has some bugs, but the pinball game has gotten to the point where it's plenty presentable for the Maker Faire. I'm pretty proud I got this thing to go as far as it did, there were soooo many kinks to work out, mostly due to errors in the schematic. These builds are giving me a helluva education in digital electronics...

IN JUST OVER A WEEK, I'm going to be at the Rochester Maker Faire showing off my TTL game builds! I have so much crap to do until then, hope I can figure out how to decently graft on a debouncing circuit to a couple inputs

BTW, if you want to read more details about my adventures in TTL video games and building them, I've been journaling about it here. There's subsequent posts detailing other builds, including one that's a sort-of proto Space Invaders.

This is what I've been working on lately - building video games from schematics and designs out of the 1978 book How to Design and Build Your Own Custom TV Games by David L Heiserman. This one here is a pinball game, and its in a playable state (though still kinda janky). I'm adding sound to it now.
It's done ENTIRELY in TTL!
