After many trials and following troubleshooting tips suggested, the system display remains after many attemps, as follow:
-
----------------------------------------
Break
----------------------------------------
A=10 B=BD X=E0D7
----------------------------------------
C=D9 S=0112 P=011B
----------------------------------------
The system behaves as this:
Start by switch on : display appears after the "beep" tone" that I interpreted as encouraging, but:
Switch off doesn't clear the screen
Push on the reset button clears the screen
Some info about the machine:
Serial: 010884.
Should be running BASIC V1 and has the opening over the 6301 VOP C63010 CA
Basic M64030AA ROMS:
ROM0: A2X145
ROM1: A2X144

Dip switch settings: OFF ON ON OFF : French Keyboard (Membrane type)
Power supply: new sub-Cells (1500mAh) installed; recharged using the original transformer.

Any suggestions are welcome and I would be more than happy to see this machine up-and-running again.
Many thanks in advance.
