44cc9f3f6d TT2500: Turtle Terminal 2500, from General Turtle Inc. 
Custom TTL design by Marvin Minsky.  There are two displays: one
raster scan for bitmapped characters, and another random scan for
vector graphics.  There is also a keyboard, and a UART for talking
to a host computer.

The computer is normally booted off a ROM which reads and starts a
secondary loader from the UART.  The loader is responsible for reading
the payload, which comes in checksummed blocks.  The LOAD command
accepts files in same format.
