Yes, the switch position should be selected before powering on.
The so called "Turbo-switch" has 3 wires and 2 static positions (1-2/2-3).
For the original ROM Selector on Q40, we need only the (2-3) position, the
other position should be open. So, the wire 1 should not be connected.
Thanks Dave, D
My apologies. I misunderstood.

No. Alain wants to use the turbo switch, not the reset button.

As the reset button is momentary, it will also take a bistable flipflop
like a 7474...
When I get back, I'll do you a little circuit. :)

Thanks Peter for your comments.

Congratulations, you are ahead of the Q40 designer ;) I have not yet
tried the latest SMSQ/E version from
On my old good Q40 platform, I used a very early unusable SMSQ/E ROMed
