One other thing, which I just found out --

If you can't boot with the add-on display controller in place,
you will probably have to set DIP switch 7W (closest to the back
of the machine) to "No controller mode".

Switch
 1  2  3  4  5  6  7  8
 -  -  -  - on on  -  -


Don't forget to write-down the original switch settings!

Good luck!
