TerribleFire TF520, TF530, and TF540Stephen Leary's open-source DIY accelerators for the Amiga 500. Documentation on how to build the 68020 and 68030 CPU versions (TF520, TF530) are already available via GitHub and YouTube (see links below), and just recently Stephen has begun developing the 68040 version (TF540).
CPU: 68020, 68030, or 68040
Here's a demo of the TF530 in action, comparing a stock A500's performance to that of a TF530-equipped one, using "Frontier - Elite II":

phase 5 BlizzardPPC 2PowerPC accelerator for the Amiga 1200. Not much is known about this new beast from phase 5, only a few pictures have been posted to their facebook-page. But as far as one can tell from their announcements, they're seriously getting back into business.
phase 5 AmigaONE-1200 II board with G4 CPUExtension board for Amiga 1200 tower conversions (see previous post), with G3/G4 PPC CPU slot. As with the BlizzardPPC 2, not much is known, and there are currently only some pictures they posted to their facebook-page. But just imagine your Amiga 1200 driven by a G4 CPU...
Vampire 500 V2 and Vampire 600 V2FPGA-based accelerators - and much more - for the Amiga 500 and 600. Amiga 1200 version is in development. CPU performance far beyond that of a 68060, SAGA graphics with Full-HD resolution, HDMI output, 128MB RAM, MicroSD card slot, IDE controller (Vampire 500 only). The ultimate boost in performance!
