#m68k — Public Fediverse posts

I've shown Claude the source code of the ncr7xx CLI tool, and it figured out on its own how to use its testsuite to validate the emulated A4091 controller.

Claude knows the #m68k architecture inside and out, and surprisingly also knows the #Amiga hardware and #AmigaOS very well.

Then, I used the #Copperline A4091 emulation as reference to to fill-in some gaps in the existing Amiberry / WinUAE implementation...

...and even to fix a bug in the ncr7xx tool!

Уникальный смартфон из 2002'ого с процессором m68k и GPU: инженерное чудо Palm i710

Мы все с вами привыкли, что начиная с 2000 года, на рынке мобильных процессоров доминирует ARM. Сегодня устройства на базе данной архитектуры окружают нас везде: смартфоны, колонки, вейпы, часы и многие другие устройства. Однако раньше всё было не так и когда-то основным конкурентом ARM была легендарная компания Motorola... В 90-х годах, Motorola m68k был знаковым процессором. Он использовался во десятках легендарных устройств: компьютерах Mac, телефонах StarTAC и КПК от компании Palm. И в 2002 году, Palm представила свой первый коммуникатор — i710, который сочетал в себе классический процессор из 90-х и современный радиомодуль. Сегодня мы с вами разберем это чудо инженерной мысли, изучим его схемотехнику и компонентную базу, и узнаем, на что был способен этот красавец на практике. Если любите настоящие технарские статьи — жду вас под катом :)

I'm a bit worried about the temperatures in my #Amiga500.
The CPU is a ST TS68000CP8 and according to the datasheet, the operating temperature range is 0 to 70°C. After an hour of activity, it is almost 80°C...
The Denise (OCS) has same operating range and stays under 60°C, so inside the range.
The fat Agnus (ECS 1MB) almost reaches 60°C, but I couldn't find a datasheet, yet. I suppose it's fine, too.
The MC1488 (U38) is the serial line driver, and reaches almost 50°C, although I can't explain to myself why - I have nothing connected and it is a high temperature for idle.
The 74F244 buffer (U35) in the RAM circuit almost reaches 50°C, too - also within the 0 to 70°C range.
The CPU is worrying me most.

I love these kernel hacks!

> #Mackerel-08 now boots the #mainline #Linux #kernel! That's v7.1-rc6 at the time of writing. An 8 MHz-rated #Motorola 68008 (here running at 14 MHz) and 3.5 MB of RAM are enough to boot the latest kernel into userspace and provide a minimal BusyBox shell. […] This 40+ year-old cost-reduced CPU was not a powerhouse even in its day (the 68010 came out the same year), yet it boots the same kernel as my new Ryzen desktop.

@wyatt As I understand it, there isn't enough data on the 68000's stack frame to properly recover from an aborted instruction (bus error or address error), but there is enough to recover from an illegal instruction and emulate it. That's what the line A and line F exceptions were originally meant for: emulating things that Moto was going to put in later processors.

Google mail client in Android refuses to login on other addresses than gmail.com!!!

I noticed a while back that the Google client fights back when I want to login on my email addresses which deviate from the Google domain. The client started with putting delays, before opening those accounts. It also randomly injected that those accounts were not safe while all standard Open Source safety measures are taken on both the servers and the clients.
When scaring you into using your {own hosted} email server fails, the gmail Android client degrades to the following behavior

The Google mail client in Android blatantly refuses to open the mails on those addresses.

##The Android client fakes, hallucinates, out of memory errors...

...even when all other programs on the phone have been taken out of memory. It's like someone put in LLM hallucinated slop code in that part of the gmail client

Very anti-consumer this Behavior

Of course I have an Open Source e-mail client running 🎽 on my Androids

I've seen this behavior coming years before. No I'm not going to recommend any open source email client to you, to use on your Android, to fetch and process your mail.
There are enough choices to make your own

Just remember that Google hates all of us

Google hates their clients

Google as a company hates their consumers never forget that

jump ship.

Google is now the Bell Phone Company of the 1960s

@starsk Here's a closeup.

My A500 borrowed an A1000 keyboard while waiting for the https://a1200.net one.

It also has a PiStorm Classic, but it doesn't play well with the A590 and any expansion that tries to do DMA. I'm working on a CPLD patch to emulate the #m68k bus granting protocol.

Having just read some #PDP11 assembler code, and similar in #m68k, #sparc, and #i386, my big take-away was that literally everything in computing would have been better in a world where #Zilog won.

Retro68: если вам скучно жить на свете

Конец ноября в Питере — крайне мрачное время года, на улице лишь холод, сырость и уныние. Что определенно влияет на психику местных жителей, порождая в головах самые нездоровые желания. Видимо по этой причине, одним мрачным осенним днем мне захотелось создать графическое приложение на современном C++ под.. классический Mac из 90х.

Ein Mac OS mit Motorola 68060? Nativ? Also nicht im Emulator/auf einem Amiga?

zigzagjoe hat einen Hack gebaut, der es erlaubt, ein Werk-MacOS 7.1 auf einer Quadra 650 mit 68060-CPU zu booten. Hacky, unfertig, kein Produkt, und er will nicht weitermachen, aber es ist ein Riesenschritt, und es ist OpenSource!

Ein 68060/66 dürfte in einer Quadra 650 das ~3fache an CPU-Geschwindigkeit bringen, gegenüber der Werks-CPU 68040/33. Doppelter Takt, mehr Cache, schnellere Befehlsausführung, bessere Sprungvorhersage etc.

Aber es ist noch etwas Arbeit durch Freiwillige zu erledigen, an ROM-Patches.
