I was trying to find if there was a version string somewhere in the ROM to confirm that actual version. I did come across a diagnostic routine (tried to find similar earlier with random key presses during startup but no luck).
ROM 1.03:
Diagnostic 1.03.27 (960523) by NER
ROM 2.??:
Diagnostic 1.04 (930402) by NER
Newer version ... but older date ... interesting. Not sure how to trigger it yet ... it's near the "Terminal mode" code ...\
