The KIM-1 is the best known development system by MOS Technology.
But a more advanced, more expensive ($3950) system, quite rare now, is the MDT 650.
Here I present you the MOS Technology brochure, an article in the Microcomputer Digest and a userguide as published in the book Microcomputer Systems Principles featuring the 6502 KIM.
Software for the MDT 6502 was developed by Computer Applications Corporation, COMPAS.
