A brand new 68k Mac emulator quietly dropped last night!!

“Snow” can emulate the Mac 128k, 512k, Plus, SE, Classic, and II. It supports reading disks from bitstream and flux-floppy images, and offers full execution control and debugging features for the emulated CPU. Written using Rust, it doesn't do any ROM patching or system call interception, instead aiming for accurate hardware-level emulation.

on june 5, bill atkinson passed away at the age of 74 at his home in portola valley, california. his family confirmed the cause was pancreatic cancer.

before the macintosh, computing was still largely limited to text commands. atkinson’s contributions made personal computing visual, intuitive and human centered. he believed deeply in the potential of technology to empower creativity and expression.

Happy #aMAYga 😁 Introducing the newest addition to my vintage computer collection!

I picked up this A500 today from a local seller (much more reasonably priced than eBay) who bought it new around 35 years ago. It comes with the mouse as well as a second disk drive and the famous 1084 monitor. I also got a box with a ton of floppy disks for it thrown in (not pictured). It's a little bit yellowed but otherwise seems to be in pretty good shape. Powers up to the insert disk screen and I was able to get a few floppies to boot as well.

I'm super excited because unlike Macs and PCs of the era, I know next to nothing about Amigas, and this is only my second time actually using one. But I know they were great for gaming and multimedia/AV applications so getting one has been a bucket list item for some time - and I've heard that the A500 in particular has a lot of modern QoL upgrades available which I'm excited to check out.

🎉 Announcing #Macstodon v1.2, the premier Mastodon client for vintage #Macintosh computers!

This release features the all new Toot-To-Speech (TTS) technology! Select any toot, click the Speak button, and Macstodon will read the toot back to you, using whatever voice you have selected in the Speech control panel. It works with MacinTalk 2, 3, and Pro, all the way down to 68020 machines running System 7.1.

Also featured in version 1.2 is improved stability and error handling. If Macstodon runs out of memory or encounters an unexpected error, it will save a log to the application folder, show you a dialog explaining what went wrong, and exit gracefully.

Of course, all the usual features are still there including timeline/profile browsing, toot posting, and interactions!

Download it from GitHub: github.com/smallsco/macstodon/
(don't forget to read the Read Me file, it contains important setup instructions!)

Happy #MARCHintosh to all who celebrate!

This year, I'm starting off the month with a collection of #VintageMac #NuBus video cards that I've picked up off eBay over the last couple of years. It's time to find out...
...which is the fastest/slowest?
…which one(s) are accelerated? (or _pretend_ to be)
…does having the drivers installed make a difference?
…what resolution and colour depth is supported? (Is lowendmac correct?)
...do they support breaking into MacsBug?
…can they boot into Linux? Or do they only work under #MacOS?

The results may surprise you!

Here's how it's going to work. Each day, for the next few days, I'm going to take one of these cards and put it into my Mac IIfx, running System 7.1.1. I'm going to run at least two benchmarks - a full benchmark from Speedometer (so we can see if, say, the video card degrades CPU performance) - and a video-only benchmark from MacBench 3.0. (1/2)

Welcome to #MOVember, one asm MOV instruction each day.

The Motorola MC68000 has a BEAST of a MOV instruction.
Official assembler mnemonic: MOVE. Refreshingly clear!

You could move to and from registers and/or memory. 8-, 16-, 32- data sizes. Post increment, predecrement. Including memory-to-memory moves (*Ferris Bueller soundtrack voice*: Oh Yeah).

`*d++ = *s++` is a single instruction in 68000.

Officially destination on the right: MOVE A7,D0 copies the A7 register to D0
