What helped me deliver my RetroChallgence 2024 project on time? Prior experience with the Interlisp API of NoteCards and the nature of Lisp and Lisp systems.

RetroChallenge announced the results of RC2024/10 and I'm honored to be among the winners. I entered with the WebCard project written in Interlisp, a NoteCards extension for visiting websites.

Thanks to the organizers, voters, and judges and congrats to all the entrants, especially @psychotimmy who won the Grand Prize.

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.

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 . In the weeks after the challenge it went on to emulate the #MZ80A as well. The plan for this winter is to have a bash at #MZ700 emulation. The architecture isn't hugely different from the earlier MZs, but I'll need to implement colour output as a minimum.

Eight worlds. Countless retries.
Mine carts, rocket barrels, and one very persistent dad.

And now I stand before the Golden Temple… thinking about doing it all over again. 🍌

Are the RetroChallenge 2024 entries still supposed to get the final comments? I know they may come in August or September of the following year but the 2025 edition starts in slighly over a month and there are no final 2024 comments yet.

I had a lot of fun entering the challenge, my first one, with a Medley Interlisp project that extended NoteCards to visit websites:

Code Protection Showdown: 1980s Edition! Transform Your BASIC Code Into an Impenetrable Fortress (or a Maze of Utter Despair) #retrochallenge. Full details here: https://hacking.museum/index.php/2024/11/07/code-protection-battle-1980s-style-how-to-turn-basic-into-a-fortress-or-a-maze-of-despair/.

We’re gearing up for a wild weekend as Hacking.museum sets up shop at the UnlockYourBrain hacking conference! Expect a ton of retro-style hacking madness, complete with our animated retro ISP modem setup and a series of nostalgic CTFs featuring the ZX81, ATARI ST, and more. See you there! #retrocomputer #retrohacking

Final wrap-up for #RetroChallenge from me this year. Did the #ZX81 module for the #RC2014 live up to the #RC2024 expectations? Find out here https://rc2014.co.uk/3331/retro-challenge-2024-10-schrodingers-pcb/

Of course, almost as soon as I'd finalised my Pico MZ-80K 1.0.0 release I found a bug!

😩

Some (definitely not all) games written in machine code have difficulty in picking up keyboard presses.

I suspect this is because they're reading the keyboard scans directly, rather than behaving nicely and using the monitor subroutines provided for that purpose.

I think I should be able to fix this, but it may be quite tricky.

Finally: do you want to see the #RetroChallenge #PERQ 2T2 on the bench in person? Come to the Retro Computing Festival at Cambridge’s Centre for Computing History on the 9th and 10th — you’ll find me there wrestling with it live!
