Anyone use No-Slot Clock in a Slot? [message #340371] Mon, 27 March 2017 00:04 Go to next message

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,

Only the NS.CLOCK.SYSTEM driver supports the slots. The other two I know of don't. (SWU.SYSTEM and the GEOS driver.)

When writing the AppleWin NSC emulation I disassembled parts of those existing drivers and summarized what memory areas they support.

The disassemblies and summary are here:

Cheers,
Nick.

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.
