PiStorm32-lite: Assembly instructions of CM4 adapter published
Claude Schwarz' PiStorm connects a Raspberry Pi to the CPU socket of an Amiga via an adapter and uses the British single-board computer to emulate a fast m68k processor. The lite version is supposed to take into account the current difficult situation in the procurement of components and in principle be cheaper (amiga-news.de reported). Basically, the adapter is intended for use with a PI3A, PI3B, PI4B or PiZero2. But for some time now, Emu68 developer Michal Schulz had been working on the development of an additional adapter that would allow the operation of a Compute Module 4 instead of a Raspberry Pi (amiga-news.de reported).
The work on the CM4 adapter and on adapting Emu68 to it is now complete, so Schulz has published the corresponding circuit diagrams and building instructions on GitHub.
The CM4 is basically a Raspberry Pi4 on an even smaller board without peripherals, which is intended more for industrial applications. Since the CM4 does not have the usual 40-pin header, it cannot be operated alone with the PiStorm. Schulz's CM4 adapter board is needed for this.
Basically, the developer tells us, there are already many adapter boards for CM4 on the market, but they have a problem: they would fit together with the PiStorm32-lite, but would not have the right size to ultimately fit everything in the Amiga's expansion slot. There is a risk of overheating and short circuits.
The adapter board he designed was specially intended for the PiStorm32Lite and fit together like a glove. Furthermore, there is enough space for a heat sink and fan. In addition, his adapter board has a ribbon cable connection to which an IO card developed by Claude Schwarz (also to be released soon) can be connected, with which the relevant connections such as HDMI, Ethernet or USB can be routed out of the back of the A1200. This will reduce cable clutter. Finally, the CM4 adapter offers an NVMe slot. There is no driver for it yet, but in the future it will be possible to connect an NVMe hard drive. (dr)
