Forty years ago today, the Commodore Amiga 1000 was released to the world. With its unprecedented graphics & sound capabilities, powerful 16-bit CPU and custom chipset, and UNIX-like multitasking OS, the Amiga was a truly revolutionary system for its time. And, many are still in use to this day, with the platform seeing new software and hardware development from month to month.
I presently have three, myself. :-)
Happy 40th, Amiga!

I am looking for an Amiga 2000 CPU accelerator that features a physical enable/disable switch.
Anyone have one sitting around they're looking to sell? I'm using a 68020 accelerator now, so anything would be faster.

Thinking of NEXTSTEP this morning...I'd guess many aren't aware of the unusual color display arrangement.
The NeXTstation, which was the first "affordable" color solution for NEXTSTEP, has a 16-bit framebuffer, but instead of rendering the desktop in 65,536 colors (as per Windows or Mac hardware, say), it rendered in 12-bit color with 4-bits of alpha channel (transparency).
That means it had a palette of 4096 colors, with all colors available at once on the display (not like, say, the Amiga or Apple IIgs with a 4096 color palette, but video modes with a small subset of those colors available (yes, yes, HAM mode excluded). Additionally, anything on the screen had 16 levels of opacity available.
It's interesting to see in person, on the actual hardware (especially on a good LCD display). With dithering, it looks very close to 24-bit truecolor.
(The NeXT Dimension color board for the Cube allowed 24-bit color with 8-bits alpha, but that was not so frequently used -- less so than most NeXT hardware even...)
But that's not nearly the weirdest that NEXTSTEP-capable hardware got, when it came to color video display...

Oh le joli microprocesseur 8/16/32 bits (c'est compliqué).
Il va falloir que je fasse quelque chose avec ça !

Are there any #MC68000 #mc68k gurus in the audience?
If a program running in usermode accesses the vectors via a data access instruction - what does the 68010 indicate on the function code pins?
Are vector reads escalated to being supervisor code/data reads, even though the code which triggered them is user-mode?I'm trying to figure out why dereferencing a null pointer is 'fine' on a real #UnixPC but causes problems with the FreeBee emulator (if I disable vector access promotion).

Someone asked me about the PGA chip sitting on my Mac Studio in a recent toot showing some little glass figurines I brought back from Murano, Italy. They asked if it was a 386. It is, in fact, a ceraminc PGA 68-pin MC68HC000RC12. I didn't have a very clear shot of this chip I recently picked up off eBay, so I took one this morning to share with the person who asked -- and it turned out a rather striking image, to my eye.
I thought I'd share.
(I recently purchased the chip in new condition on eBay because of its nice, square purple ceramic and gold appearance (just to have as a desk bauble) and with a nod to the many MC68K systems I've used over the years -- and still use today.)

Latest book: MC68000 Assembly Language Programming Second Edition by B. bramer & S. Bramer
Looks like this book was never used as it's still got the original receipts from 14 Dec 1991

I found a monitor cable included. I still had a DB15 to VGA adapter. Now the #PowerBook540 has at least some color display in the amazing resolution of 800x600 pixels on the flat screen TV.
