Back to 1999, the M5407C3 board was shipped with one Am29PL160C (2MByte) Flash ROM.
The first 256K of the Flash contains ROM Monitor firmware, named "dBUG", which provides the user with debug interface, inline assembler and disassembly, program download, register and memory manipulation, and I/O control functions.
The rest of the Flash was available for the user.
My board was saved today from the hydraulic press, someone must have reprogrammed the whole Flash because the VxWorks bootloader is the only thing that appears on the serial and there is nothing else in it
By chance does anyone have a copy of the have a copy of dBUG?
