How to resume the 6510 after being stopped the hardware way.

The /DMA line in the C64's expansion port allows to stop the CPU in the same way the VIC-II does.

I wired a probe tip and with the computer in the BASIC boot screen I shorted the wire to ground.

The cursor stopped blinking. I opened the short back and the cursor doesn't resume blinking. I shorted the wire to VCC, in the hopes it would be interpreted and "gone high" but the cursor won't resume blinking.

I then wired /IRQ and shorted it to ground, trying to pull it low, with the hope of forcing the standard interrupt routine to work with no success.

I would like to know how to make it work.

Thanks.
