This is a one bay NAS originally shipping Linux 2.6.24.4. It features - 128 MiB RAM - 2x eSATA (1x internal, 1x external) - 2x USB 2.0 - 4 MiB NOR - battery powered RTC on i2c (PCF8563) - 1x GBit ethernet For now only the low-hanging fruits are added to the device tree, eSATA, USB, i2c and networking needs more work as there are no drivers available. Such a machine was offered to me by Richard Fröhning. Thanks!
