Sam440ep
Sam440, also known by Sam or its codename Samantha,[1][2] is a line of modular motherboards produced by the Italian company ACube Systems Srl.[3] The Sam440ep version is a Power Architecture motherboard based on the PowerPC 440EP system-on-a-chip processor which includes a double-precision FPU. It is made by AMCC.[4][5] Their primary targets are the industrial and embedded markets, running operating systems such as Linux and AmigaOS 4.
At the time of release in 2008, it was the only AmigaOS 4 compatible hardware since the AmigaOne machines ceased in 2006; as of April 2009 Sam440 was the only Amiga-compatible board in production and now is succeeded by the Sam460ex (AmigaOne 500) and AmigaOne X1000.
Main features
Notable features of the Sam boards (including all versions):[6]
- Low power consumption
- Passive cooling (no CPU fan)
- Scalability
Versions

- Cache L1/L2: 32KB/-
- 128/256/512 MB 266 MHz DDR SDRAM soldered to the motherboard
- 1× 32-bit, 33 MHz PCI slot
- 1× Flash memory device controller
- 4× USB2 ports, 1× USB1
- 2× Ethernet 10/100 ports
- 4× Serial ATA ports
- Cirrus Logic CS4281 and Realtek ALC655 audio
- ATI Radeon Mobility M9 graphics with 64 MB VRAM, s-video and DVI out.
- GPIO expansion connector
- Lattice XP expansion FPGA
Revision C
The specifications are the same as for the revisions before, except for:
- 1× DDR RAM slot supporting up to 512 MB RAM (in place of soldered RAM modules)
Sam440ep-flex
There is no graphics chip on the Sam440ep-flex, so you have to use a PCI-graphics board.[7]
Prototype

Revision 1
The specifications[8] are the same as for the flex prototype, except for:
- 2× DDR SDRAM, max 1 GB RAM
Revision 2
On 2 April 2009, ACube announced the availability of SAM440ep-flex revision 2, it has the same specifications as the flex prototype except for:[9]
- 667/733/800 MHz AMCC PowerPC 440EP SoC processor (passive cooling, 733 and 800 MHz are achieved by overclocking)
- Cache L1/L2: 32KB/-
- 2× DDR SDRAM, max 1 GB RAM
- RAM clock running at 133 MHz (667 and 800 MHz models) or at 147 MHz (733 MHz models)[10]
