I think it's finally ready to be poked at:
https://github.com/glitchwrks/gwmon-65This is a monitor that follows the same command syntax and input/output formatting as GWMON-80, our small monitor for 8080 and compatible systems. It's not really a straight-across port as parts were rewritten to take advantage of the 6502, rather than trying to cram 8080 patterns into 6502 syntax.
The monitor has four basic functions:
Dump memory,
Edit memory,
Go to address, and
Load Intel HEX data. The README covers command syntax. The
D command output is parseable by SRecord's -hexdump option.
GWMON-65 SM with Motorola 6850 I/O initialization and reset/NMI/IRQ vectors fits in 512 bytes, which means it'll work with very old systems like the Ohio Scientific 400 board, which uses two 1702A 256-byte EPROMs.
Like GWMON-80, GWMON-65 is modular, to make it easy to create new customizations for systems.
Feedback appreciated!
