Model: Soekris net4511
CPU: AMD Élan SC520 (Am586DX)
RAM: 64 MB
Storage: IDE CompactFlash, 32 MB originally (upgraded to 2 GB)
Not quite a fully-featured host, but an interesting piece of hardware nonetheless.
Based on AMD Élan SoC – a 586-based system-on-chip – the net45xx series were single-board computers much like the Raspberry Pi and similar, but primarily meant for use as routers, given their dual Ethernet ports and the option to route antenna ports for a Wi-Fi PCMCIA card. (The highest reported throughput I'd seen mentioned on forums was around ~65 Mbps.)
The net4511 has no VGA output; its custom BIOS reroutes text-mode input/output through the serial port. It can network-boot using PXE, which is one of the few ways to install an OS (other than resorting to a VM with the USB CF card reader attached).
Originally this unit ran MS-DOS with LEMAbridge; at the moment it runs OpenBSD 4.4, as that was the easiest to net-install.
