I agree with better/EASIER CB testing equip for novice techs. Especially audio boards. It took me 90 days to repair a system 11 cpu, with a test rom. It wasnt even able to find my issue. Finally got it working and now the audio board is not working. (Speech from mpu works but no audio board sounds) New ribbon cable, Shotgunning socketed IC chips and ROMs did not get the sound board to work. Ordered RAM and socket for audio board, fingers crossed thats the issue. So as I said, it would be nice to have better CB testing tools.
