Halloween with the Camels
It’s time to close out this year’s RetroChallenge project. Since it’s October, why not use the Forth interpreter that I’ve been slowly building up all month to do a sort of demo? I hear decorative squ...

Forth on the SG-1000 is such a fun RetroChallenge pick. Congrats on finishing! Did the gourds get a tune? That SN76489 would make a fine spooky beeper.

I tried to look up Retrochallenge back in August, to see if one was planned, and didn't find anything, so I assumed it was off. Now I found out, two days before the end, that it is in fact on.
Grrrr.

New blog post! As the #CamelForth RetroChallenge project continues, I test it on real hardware and solve a long-standing bug. All building up to an exciting Halloween ending! www.leadedsolder.com/2026/10/27/c...

No longer a theoretical Camel
In theory, theory and practice are the same thing. In practice, they’re not. That’s sort of the same problem with emulators – even the best ones are not always the same as real hardware. Although MAME...

New blog post! With the sound chip out of the way, it's time to introduce Forth to the awesome complexity of the TMS9918A, starting with sprites. Put a smile on your screen today! Do not taunt happy fun smile. #retrogaming #forth #retrocomputing #retrochallenge www.leadedsolder.com/2026/10/20/r...

Now that we have a working Forth environment running on the SG-1000, it makes some sense to start building up the video display capabilities. Can I get sprites working on the TMS9918 for the first tim...

New blog post! I got to write some actual Forth, in an effort to make my Sega SG-1000 make sounds. Let's all learn about the stack!

For this year's #RetroChallenge I am looking at using the SPI protocol from a #RC2014 computer.

In this post, I show how I was able to control a MAX7219 LED Matrix using Z80 assembly language.

New blog post! The Sega SG-1000 is a great computer/console hybrid, but its BASIC just doesn't cut it. How about porting over an interactive interpreter for Forth? The project begins today and runs all month.

More like SC-Forth-thousand, am I right?
The Soggy needed a good low-level programming environment with which to tinker on future hardware projects, and ideally it was one that I controlled myself, so I could include it on the onboard ROM wi...

Totally stunned that the Pico MZ-80K won the "general" category in last year's #RetroChallenge! Thank you to everyone who voted for me, followed the project, etc. etc. etc. #RetroComputing

I'm not able to take part in #RetroChallenge this year, but I've just spent a few minutes enjoying last year's writeup of my #Sharp #MZ80K emulator for the #RaspberryPiPico . The plan for winter is to have a bash at #MZ700 emulation - faster clock & colour too!

There was a native gui editor for 42nix (my team did use it, but preferred vi as it was standard across UNIX workstations). The little-known ded text editor was also available. See my abandoned 2023 retrochallenge for details and a link to the MG-1 manual entry. z80.timholyoake.uk/retrochallen...

Quote me with your first computer.

#SharpMZ80K Christmas 1981. I still have it in working order.

I also recreated it on a #RaspberryPi Pico for #RetroChallenge in October!

I'm still playing with the Sharp MZ-80K Pico emulator I created during this year's #RetroChallenge. Trying to emulate a floppy disk format and drive where there's precious little information around is ... challenging!
