Hello all, I almost completed my MB6582 and I am stuck at testing the main board. My idea is testing the PICs are running before inserting the precious SIDs. I flashed all 4 chips with "setup_mb6582.hex", but nothing happen on the LCD... I also flashed the 1kHz test FW --> nothing... :no: Supply voltage is OK on all pins and MCLR (pin 1) is high as expected. Cannot see any waveform at the oscillator's pins (10MHz XTAL and 33pF caps are OK). I would say the internal oscillator is not set for external xtal... Anyone got a similar problem starting from blank PICs? Thank you, Walter
