Sam440, also known by
Sam or its codename
Samantha, is a line of modular
motherboards produced by the Italian company
ACube Systems Srl. 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. Their primary targets are the industrial and embedded markets, running operating systems such as
Linux and
AmigaOS 4.
No new official hardware has been released for AmigaOS 4 since the AmigaOne machines ceased in 2006; as of April 2009 Sam440 is the only Amiga-compatible board in production.
Main features
Notable features of the Sam boards (including all versions):
Low power consumption
Passive cooling (no CPU fan)
Scalability
Versions
Sam440ep
Sam440ep was the first modular motherboard produced by ACube Systems Srl.
There is no graphics chip on the Sam440ep-flex, so you have to use a PCI-graphics board.
