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. |
