Getting System 7.5 natively booting on a G4 Mac is impressive enough…

...but what truly blows my mind is that on the same hardware, the author managed to get System 6.0.8 as far as a Happy Mac, and Systems 7.0/7.1 to a "not supported on this computer" dialog.

The fact that the ROM manages to get that far at all, instead of a black screen or sad mac is bonkers, considering that the processor architecture (and the rest of the hardware) is completely different from anything that would be understood by that era of OS. It's relying on the 68k emulator built-in to the ROM.

Driver support notwithstanding, I wonder how low could you go if you took the resources from the CHRP system enabler and brought them over into the System file directly? Since 6.x and early 7.x didn't support enablers.

Texas Instruments has discontinued the venerable Ti-89 (and titanium) graphing calculator this year after 27 years. Is this the last consumer device to ship with a Motorola 68k processor? #Ti89 #68k #Calculator

🌘 為 68K 軟體 SimpleText 注入補丁：客製化視窗大小
➤ 深入淺出：手把手教你修補經典軟體，打造個人化 SimpleText
✤ https://tinkerdifferent.com/threads/patching-68k-software-simpletext.4793/
本文詳述作者如何為經典的 Mac OS 應用程式 SimpleText 進行程式碼修改，以實現啟動時開啟較小文字視窗的功能。作者透過反組譯碼、尋找關鍵系統呼叫（如 _SizeWindow），並巧妙地利用程式碼注入技術，在不破壞原程式邏輯的情況下，修改視窗尺寸判斷邏輯。過程中克服了程式碼空間限制、暫存器重用以及資源管理等多項挑戰，最終成功實現了客製化視窗大小，並分享了針對 CodeWarrior 的幾項實用除錯技巧，同時建議儲存額外設定資源以方便未來調整。
+ 這篇文章太專業了！我對 68K 程式碼注入的細節完全看不懂，但看到作者能克服這麼多技術難題，真的很佩服！

GlobalTA/UX’ing tonight!

It's been quite a while since I’ve done something silly with an old Mac so I installed A/UX on my IIfx. It's something I've wanted to do for a while (and tried a few times in the past) but never managed to get it to work until now - turns out A/UX is incompatible with the BMOW ROM-inator - after reinstalling my stock IIfx ROM it works like a charm, even supporting my Interware video card and Asante ethernet card.

Software compatibility is a bit spotty when it comes to network apps - iCab and TurboGopher didn't work, but MacLynx and the Wikipedia app do. And of course #GlobalTalk works like a charm!

Also it's crazy that I can telnet into this thing from my daily driver MacBook Pro 🤣

Photo of the monitor attached to my Mac IIfx running A/UX 3.1.1, there are four windows open - a command shell, the Chooser, the Wikipedia app, and MacLynx (with FrogFind loaded).

These are now the definitive Amiga 40 streaming details from Mönchengladbach for Saturday and Sunday. There may still be minor changes to the stream depending on the previous topic.

May now be officially published everywhere.

Updated the #Macstodon roadmap today.

It's been a long time since I've touched it, but things slowed down a little bit at my day job this week and I'm getting the itch to do some retro programming again.

I need to tackle the longstanding Mastodon 4.3+ auth issue and I think I'm just going to build a wizard-type interface with screenshots that show you what you need to click (on a modern machine) in order to create an auth token manually.

Also it would be nice to support the new quote posts feature. And polls. And maybe even attachments.

I gave up on the REALBasic/FutureBasic rewrite - it was too difficult to do that and still maintain System 7 & 68K support (and also because someone else is working on a Mac Mastodon client in REALBasic for later OS versions).

I do still want to rewrite it in Micropython but that’ll be a LONG way away and is dependent on Micropython getting all of MacPython's features.

Anyway, hopefully I'll have more to share in a few days/weeks.

Wow, second time in seven days. Another package that's been lost in the post for over two months had turned up unannounced in my mailbox. This time its a #68K assembly language manual 👾

A dogeared textbook titled 68000 assembly language programming

And now I wonder how hard it could be to patch a 68K silicon graphics IRIS 3000 to run classic mac os. I doubt I'll have time in my lifetime to look into that, but still making QuickDraw work with a bitplane graphic adapter would be interesting…

A pretty good video about the Motorola 68k. It’s fascinating to see how many things were powered by it in the 80s and 90s, like macOS 8 in 1997.

@llamasoft_ox I grokked #6809 first and then a fair bit of #68k when I moved to the #atarist and started writing demos. My summer job at Flare technology was a wake up call as I moved from clear opcodes and register naming to x86's implicit targets and much more limited register space. Nowadays I probably spend most of my assembly time between x86 and #arm and at least 64 bit added more registers to use.
