Working on More Cool Things™ for jcm-1.com

How about a JCM special version of the MiniPerformer+ for the Mac Plus, that clips over the CPU?

No soldering required. No permanent mods.

Interested? Sound off in the comments.

1) Install 24H2. Use bypass. Install all updates.
2) Use Pro instead of Home. Say you're on a domain.

All I need to figure out from here is where in memory this system stores it's NOAA settings. I mean, I seem to have found a -copy- of it used for data entry in the menu, but not the real data.

With that, I can find other routines that read those data, and reverse engineer those.

Maybe.

Reverse engineering a re-entrant multitasking Z80 operating system for bespoke hardware with no source code and almost no Z80 experience isn't exactly easy.

But I'm trying. Tonight's Spectragen progress:

Being laid off stinks. That said - I have free time now! I think it's time to finally finish editing my interview with ZSKnight (one half of the original developer team of ZSNES in the 1990s). Let you all know when it's done, should be this week, and I hope you all enjoy.

You don’t have to self-identify as a pederast to be one. You just have to abuse children.

You don’t have to self-identify as a murderer to be one. You just have to murder people.

This is a post about Fascism.

“Antifa” considered as a singular organization is the ultimate expression of the conservative tendency to invent a guy and get mad at him.

A picture of Carol Shaw sitting on a chair holding a copy of River Raid. Above her it says "Meet Carol Shaw, the first female video game designer in history. In the late 1970s, when gaming was dominated by men, she joined Atari and created classic hits like River Raid - a game that became a global success.

She proved that creativity has no gender and inspired generations of women in tech and gaming"

Below her it says "She didn't follow the game she built it joystick and all."

Related note: I should create a Ghidra server somewhere and put my work on it, so folks can collaborate on the decomp directly.

Hmm... that's for later.

Right now is sleep. Morning is order prep. Sunday is order pack.

Tonight's Spectragen Update:

I'm trying to work out how to send updated date and time to the unit. I'm very close: I can see in the code where data should be parsed, and I can seemingly send "valid" time commands to the unit: but the time doesn't update.

Any Z80 freaks out there wanna help?

Hey, Nerds!

I've updated the github repo for the Spectragen Project. Files now available for editing pages directly on your computer. It's Python, so it should work on just about anything.

Maybe one day I'll learn how to do version forks. HA!

Did you know that the Texscan MSI Compuvid Spectragen 4B can make a picture of a Millennium Falcon?

On an unrelated note: I created this screen on a PC with a Python script and sent it over serial.

The page editor works. YAY!

Still some rough edges, but we're getting there.

This is Manolo. His family invited strangers to spend time with him on his last day. His mom said, "This was such a perfect way to celebrate the life of a dog who truly loved spending time with people and their dogs. Run free and fast forever, Manolo. I will never stop missing you." 14/10 for all

It's time! After 33 years, I'm adding Gravis UltraSound support to my DOS game engine. 😄

I never owned a GUS back in the day, so it never happened. Now I've got a PicoGUS from @polpo.org (and a great emulator from @86box.net). So off we go!

Step 1A: I mirrored the final GUS SDK (v2.22) on GitHub.

Not sure even the admins know. From 10,000 feet: it seems like the admins don't know how to run a server properly.

But I'm not there, so I can't really say.
