Hi all,
Maybe to anyone of use.
A link to the testrom I created for system 11 Williams boards.
The system 11 test rom is similar to the one I created for system 3-7 mpu's in 1999.
The testrom for system 11 can be used to debug non working boards. It checks RAM and all PIA's and pia outputs.
use with care I am not responsible if you blow anything using this rom
Binary file + manual can be found at:
