An early and unlikely dual-6502 system is the MDT 650 development system: one 6502 to run the show and the other to act as the target, with some kind of support for in-circuit investigation.
See @HansOtten ’s writeup (with photos):MDT 650 MOS Technology
But a more advanced, more expensive ($3950) system, quite rare now, is the MDT 650 (microcomputer development terminal for 650x).
Turns out to be previously mentioned:
A nice story about the first resident 6502 assembler, for the MDT-650 (MOS’ Microcomputer Development Terminal):
Compas developed the software for the MDT-650 and Larry Hittel, at his company Comlog in Phoenix designed the hardware. The MDT was a dual 6502 processor development terminal with ICE capability for the 2nd processor and built-in editor and native 6502 assembler on the 1st processor. The native 6502 assembler produced by hand compiling the FORTRAN to 6502 assembly language, assembl…
