Dear Paul ,
programming new Firmware Rev 9 and rev 11 , it doesn't work for my Polaris.
It is possible to have the Checksum ?
Must I recheck all the power supply Voltage before reinstalling the new Eprom ?
Should it be RAM Problem after " mamma mia " 30 Years ??
Best Regards .
Ciao
P.S. I use the M1 - UN DP48 programmer .As shown in the Photo Below .
