Sardis Technologies ST-2900 ST-MON

The ST-2900 ST-MON monitor program is software provided in an EPROM or EEPROM that the 6809 microprocessor on the ST-2900 CPU board starts executing after powerup or a reset. It initializes the hardware, performs self-diagnostics, provides various I/O routines, and has commands to view/search/move/fill/modify/test memory, and to boot the FLEX or OS-9 operating systems from floppy disk or other devices.

ST-MON 1.01 (original release, obsolete):

ST-MON 2.50 (currently in development): New!

None of my versions of ST-MON support breakpoints, register displays, or single-stepping. However, one of my customers modified ST-MON by adding various debugging features, and gave me permission to distribute their version. Refer to disk image below.
