Anyone use No-Slot Clock in a Slot? [message #340371] |

Looking at the driver code for the No-Slot Clock, there is a lot of code to support the possibility of a NSC placed on a card in slots 1-7 for Apple ][ and Apple ][+.
The NSC manual mentions the SMT Envoy and SMT Memory Expander as examples of the NSC being installed in a slot.
Does anyone actually use the NSC this way? I'd like to make a new NSC driver and the 'slot' support is problematic.
Thanks,

I used it under the EPROM on a UDC card (slot 5), and was pleasantly
surprised that it worked. ;-)

Thanks Nick! Those are helpful.

I believe RC Systems' Slotbuster II card uses an NSC as the clock option.
