PC Weasel 2000 was a line of graphics cards designed by Middle Digital Incorporated (Herb Peyerl and Jonathan Levine) which output to a serial port instead of a monitor.
This allows servers using PC hardware with conventional BIOSes or operating systems lacking serial capability to be administered remotely.
The card may also be connected to the reset pins of the motherboard and reboot the machine on command.
Every purchaser of the board is granted a license for the card's onboard microcontroller.
The microcode, stored in flash memory, is modifiable using a gcc-based toolchain.
