pistorm

Can someone with a bit more chip-level knowledge explain to me why nobody has put a PiStorm into a classic Mac yet? https://github.com/captain-amygdala/pistorm If there are problems with the ISA or something, they're much much easier to tweak here. It already works in multiple models of Amiga, including both 68000 and 68020, and there's at least one effort to get one working in an Atari ST...

No, it isn't 64 bit at all. It claims to have 64 bit vector extensions, but that's worlds different from being a 64 bit processor. It's mostly marketing fluff. The people who made Apollo claimed for ages that FPUs necessary, then finally provided an FPU. They want people to target their proprietary extensions, but they don't even offer an MMU and emphatically claim, just like with the FPU, that it's not necessary. They spin way too much. I can't take them seriously. There are plenty of other projects that are much more interesting, like: https://www.buffee.ca/back-to-fulltime/ https://github.com/captain-amygdala/pistorm They allow for much more flexibility, the option to run on actual m68k motherboards and compatible extensions, such as an '060 emulation that includes support for instructions the '060 would otherwise need to emulate.

Fascinating! https://github.com/captain-amygdala/pistorm Oh, this is Pi 3A emulating a 68030, not a RP2040, I'll keep looking. > General Performance with the current use of Musashi as the 68k CPU emulator is somewhere around a 100-125MHz 68030. https://github.com/kstenerud/Musashi Emulating a 128k mac with an RP2040 (using Musashi) https://github.com/evansm7/umac

What fun! It's so good to see these systems still in use. The Amiga community never fails to impress. In addition to modern updates to AmigaDOS (3.2.1 is great), there are projects to replace battery damaged motherboards, to replace hard-to-find custom chips, to offer brand new accelerators, and to even use a Raspberry Pi as an inexpensive accelerator (https://github.com/captain-amygdala/pistorm) for those on a budget.

2 years to get a PiStorm amiga accelerator at a decent price (https://github.com/captain-amygdala/pistorm) due to chip shortage. Finally managed to get 3 PiStorm boards (for a more decent price than the scams off ebay), but I have only one Pi 3B, and the 3A+ or Zero 2 are nowhere to be found Only option is to buy 3B/B+ which are a little more common, at 3x+ the price, and unsolder the usb connector. Sure feels like back in the amiga days when I was waiting for the Emplant to emulate a PC and whatnot... or waiting for Gateway, Escom, etc... to do something useful... Come to think of it, it's a perfect retro experience WITH post-1994 frustrations of waiting with constant hopes and failures as a bonus :)

This isn't a Raspberry Pi powered Amiga. (Which is a thing, see PiStorm: https://github.com/captain-amygdala/pistorm) This is just a Raspberry Pi running an emulator. Any computer could do this.
