PiStorm – Keeping the Amiga alive

A look at a board that makes the Raspberry Pi 3 emulate various parts of the Amiga as a replacement for the processor. Still has a number of limitations.

The PiStorm, designed by Amiga fan Claude Schwarz [is] one that stands out from the crowd for a variety of reasons. The first is its open hardware; Schwarz doesn’t sell the PiStorm, but instead publishes the source code and design files for anyone to submit to a PCB fabricator. If you don’t fancy fighting with minimum order quantities, the community around the PiStorm organises semi-regular group buys, in which an assembled board, requiring only the headers to be soldered in place, can cost as little as $13 US (around £9 ex VAT).

Installation is simple – remove the processor from your Amiga 1000, 500 or 500 Plus, and push the PiStorm into its place. Add the Raspberry Pi on top, with a micro-SD card loaded with the lightweight Linux distribution of your choice, and you’re done.

By default, the PiStorm is configured to act as a Motorola 68020 and a 128MB chip memory expansion. Tweak the configuration and you can increase that to a Motorola 68040 – albeit with a few compatibility issues that are still being worked on – with 8MB of additional Zorro II memory – just about the most you could ever fit in a classic Amiga.

This is a pretty cool device … it makes me wonder what people are doing with their expanded Amigas.
