Raven project – A new Atari clone called Raven is in motion: designer Anders Granlund started the project in 2024 and built a custom ATX-compatible mainboard around a genuine Motorola 68060 CPU, pairing it with SIMM-based RAM/ROM and ISA expansion for running TOS/GEM setups a
He doesn’t just want to run old GEM/TOS software—he wants the hardware to matter.
That’s the mood behind the Raven project, driven by Anders Granlund and built around a genuine Motorola 68060 CPU. Instead of firing up an emulator or trying to revive an aging Motorola 68k-based Atari ST. he’s taking the hard route: designing a custom mainboard and assembling a system that can carry the Atari-era software forward.
The build has been underway since 2024. Granlund started a thread on the Exxos Forum for the project, and that thread effectively became the running log for the work as it progressed.
Raven’s core design choices aim to make the system both practical and flexible. Both RAM and ROM ICs are placed on SIMM sticks, which Granlund notes is a cleaner alternative to the typical socketed or soldered-in approach. That setup allows up to 48 MB of RAM and up to 16 MB of ROM.
The mainboard itself is ATX-compatible. a detail that matters more than it sounds for anyone trying to keep the build straightforward. It fits into a standard ATX case using an ATX power supply. and the board includes a total of 4 ISA slots. The goal is to preserve the legacy feel while keeping enough expansion room for real-world tinkering.
For the classic software experience. the Raven board bundles Atari-related support and familiar components. including YM2149 audio. IDE HDD support. and legacy Atari peripheral support. With the system assembled, it’s built to run Atari’s TOS with its GEM UI. It can also run FreeMiNT. positioned as the modern equivalent for those who want a contemporary take on the TOS/GEM workflow.
If you’re tempted to replicate it, the design files are available for the current A1 board revision. There’s one catch: you’ll need to source your own ICs.
In the end, Raven isn’t just an Atari clone in the abstract. It’s a deliberate bet that the best way to keep older software alive is to build something sturdy enough that the past doesn’t just run—it feels like it’s still there.
