All the new things of my extended BASIC interpreter for the Mattel Intellivision ECS in a second article. I almost cannot believe this is now a full-fledged BASIC, not like the toy-like original BASIC from Mattel #retro #retrogaming #intellivision nanochess.org/ecs_basic_2....

But I bought it for the printer, because it is compatible with the Mattel Intellivision ECS. I built the missing cable, and guess what? It worked on the first try with my all-new BASIC interpreter for ECS 😀✌️ #retro #retrogaming #intellivision

The Aquarius computer works. Unfortunately, only half of the keyboard works so you cannot enter to BASIC, but I was able to play Astrosmash and Tron with one or the controllers. The other doesn't work. #retro #retrogaming #aquarius

Gotcha! I don't have tested if my printer routines work.

I didn't need an Aquarius computer. But can you guess why I bought this set? 😉 #retro #retrogaming #Mattel #aquarius

I ported a Reversi game from Tim Harnell's Giant Book of Computer Games. Only changed screen, and array access from bidimensional to single dimension. #retro #retrogaming #intellivision

The final milestone to make it an useful BASIC: LOAD, SAVE, and VERIFY. Tested with real hardware using a PC as recorder/player. Now my interpreter is way superior to the original Mattel BASIC. Send it back in time and watch C64 crumble JK 😂 #retro #retrogaming #intellivision

I know, but as a kid I loved putting together weird phrases that said something when reversed.

Now my BASIC interpreter for the Intellivision ECS supports strings! 😀 A palindrome program for your enjoyment #retro #retrogaming #intellivision

Castle of Death, Intellivision homebrew by @nanochess.bsky.social. 100 single screen rooms to run thru. Tried to find the quickest ways for each room without being super aggressive, goal was just a clean deathless run. ⚙️💀 www.youtube.com/watch?v=OqLK...

One of the very best write-ups of any demoscene effect I've ever read: cobbpg.github.io/articles/nuf...

Bit-banged multiplexing taken to its extreme.

8 bits should be enough for everyone!

Are you fed up with the slow speed of your workstation?

A few days ago, I coded a floating-point package for the CP1610 processor, and then I made a brand new BASIC interpreter for the Mattel Intellivision ECS because I wasn't satisfied with the speed of the original 🤪✌️ #retro #retrogaming #intellivision nanochess.org/ecs_basic.html

after extensive wind tunnel testing and analysis, I've concluded that airplane mode is a complete scam. it doesn't change the phone's aerodynamics in the slightest.
