piStorm – A 68000 CPU replacement

What is piStorm ?

piStorm is an opensource project started by Claude Schwartz. The board fits inside the Amiga 500, Amiga 2000 and CDTV models and boosts their performance close to a 25MHz 68040 equipped Amiga 4000 (60-70MHz 68030).
Native boards for the A600 and A2000 (CPU slot) are under development.

Besides a fast CPU, which is provided by the Pi through the Musashi 680×0 emulator, piStorm with the recommended Raspberry Pi 3A+ gives you:
* FastRAM configurations up to and above 256MB without starving the Pi of RAM (3A+ has 512MB)
* piSCSI – allows you to mount up to 7 hard disk devices; supports hard drive images and even physical drives
* autoboot from hard drive image or physical drive
* RTG – gives you together with the P96 software 16 and 24 bit graphics in high resolution
* kickstart switch – specify which kickstart to use (but not really switch it other than changing from configuration file)
* keyboard and mouse passthrough – use the keyboard and mouse connected to the pi as Amiga devices

What do I need ?

* The piStorm 68000 replacement adapter
* A Raspberry Pi 3A+ or similar (Pi 3A+ is recommended because of its low profile)
* A microSD card for the piStorm software

Where do I get the 68000 adapter ?

How much does it cost ?

It differs depending on how countries add expenses on imported PCBs and components and what the shipping rates for these are at the time, but you should not accept to pay (unless you really WANT to) more than 25-30 EUR for the assembled adapter board. I have (in the Discord channel) seen prices as low as about 13 EUR + shipping.
List prices at retrorewind.ca should NOT be accepted (as for example, the RGBtoHDMI A500 adapter at $40, and the A2000 video slot version at $70!).
To that you have to add the cost of the recommended Pi 3A+ (about 30-35 EUR), and a suitable microSD card (up to 32GB is reasonable).
