For Such A Small Program, ZX81 1K Chess Sure Packs A Lot In

The Sinclair ZX81 was hardly the most accomplished of 1980s 8-bit microcomputers, but its ultra-low-budget hardware was certainly pressed into service for some impressive work. Perhaps the most leg…

Hackaday

Whew...gave me a little hassle as the plastic binding is only as big as Timex wanted. Had to fight a bit with the last few pages and back cover, but it's all back together. Time to put it away with it's machine again.

Wir haben das ZX-Team getroffen und sprechen im Podcast über Geschichte und Zukunft des kleinen Sinclair.

Also on the ZX Chess front, I did a complete breakdown of the game by creating a Z80 disassembly, understanding it, commenting it, and then creating a rebuildable version. (I also found a way to save 3 bytes!)

I won't spoil all the tricks here, but imagine my smile when I realised why the look-up movement table for the king was being purposefully ordered so it could be re-used for the queen, rooks, bishops, and (er) black pawns!

Did you know that the first Dinamic game ever was coded on a 1K #zx81? It was GT Cars.

I don't know why I felt it was important for me to implement RLE graphics decoding in BASIC on a ZX81 today, but here it is:

ZX Retro Gaming including 8 and 16 bit

Retro gaming focussed around 8 and 16 bit computers. Especially interested in Sinclair then the battle between the Atari ST and Amiga. The ZX81 my first electronic love. Support the channel : Buy me a coffee : https://buymeacoffee.com/northernstuff Channel topics include: - Tinkering with Sinclair ZX81 games, running them on other platforms. - Now the Spectrum Next Issue 2 has arrived will be messing with that, its announcement largely inspiring the channel. - I played some 16 bit games on the A500 Mini while waiting for the Next. - Winter forays into Z80 code when the weather is grotty. - Rewriting the unreleased ZX81 game Caverns for the Next as a long term project with a view to porting it back to the ZX81 at some point. - The odd gameplay video, though I’m a pretty average gamer - shoutouts to games that catch my eye. - Occasionally looking at some more modern games too. With many of the videos I am sharing my learning experiments with retro. Hope you enjoy.
