Building a C64 from Scratch: Finite State Machine Display - The Oasis BBS

Matt Regan builds a full NTSC raster display using TTL chips and a finite state machine. It's part clock, part screen, all awesome.

I made a pinball video game entirely out of TTL components based on schematics from a 45 year old book. It was.... a lot of work. But fulfilling!

So you thought the last one was tricky to get through? Brother, this one put me into an existential crisis. I’ve actually had this one done for over a year now, so details might be a little l…

A work mate gave me a tip, thanks Klaus. Much easier than learning the syntax of galasm. There is a nice project running on Java called #Digital on github. Logical elements, direct formula input, building the circuit automatically, simulate the circuit and much more. And a direct export to a JEDEC file for programming the GAL. Definitely worth taking a look at:

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...
