New blog post! What do you do when a new computer needs a cartridge in order to work at all? Make that cartridge! Today, we're having fun with the teeny-tiny Sord M5 from 1982 thanks to KiCad's new tracing tools.

Lord of the Sord

A Sord M5 home computer is disassembled and studied, and a homemade game cartridge is produced that can run BASIC and Funny Mouse. Pinouts for the cartridge bus, as well as memory and I/O maps, are provided.

Why so aggressive, Takara? Not every game is about attacking. Sometimes I just want to make one where I feed baby raccoons. #retrocomputing #sordm5
Now for my next trick, I've added Sord M5 support to CVBasic. But currently I don't have a way to test the generated binaries. #retro #retrogaming #sord #sordm5 https://github.com/nanochess/CVBasic

I couldn't find any info on how the Sord M5 detects cartridges. So I disassembled the Sord BIOS. Put a $03 byte at $2000, $2001-$2002 is the execution start address, and $2003-$2004 is a prestart address (just use $002e points to RET in the BIOS) #retro #retrogaming #sord #sordm5

The things I like most about it:

  • It vaguely evokes the feel of the ZX Spectrum+

  • It has a Z80 inside

👍

I've had the sharp blades out again and finally finished @TonyFishlock's #CGLM5 #NES controller conversion overlays. They look pretty good and match the computer nicely, the NES grey works really well.

@TonyFishlock has made a controller for my #CGLM5 using a #Nintendo #NES controller & 1/2 a cable from Amazon! Another controller on order to make a second. Makes #ChuckieEgg much easier to play 😄

Whilst at the Bring and Byte sale @computermuseum we met the excellent Charlie Robson who gave me a couple of new chips for my #SordM5 multicart. One of them has an Einstein conversion of Chuckie Egg on it 🥰🥰 It is bloody brilliant. As it was late haven't investigated the rest of the new games yet, but will do!

The other had #Colecovision conversions on it. I think we need joysticks for those, so a project for @TonyFishlock. I can't wait to try them though, looks amazing 😊

Hello my precious 😄

Yeah, probably should be turning in for the night, but ...
