This software is usable at the stock 1Mhz system clock found on all Apple 2 type computers except the GS (2.5 Mhz) and //c+ (4 Mhz). At 1Mhz it is impressive.

This software is usable at the stock 1Mhz system clock found on all Apple 2 type computers except the GS (2.5 Mhz) and //c+ (4 Mhz). At 1Mhz it is impressive. There are cards that offer up to 16Mhz clock speeds. And some can also have the 65816 CPU! Very little software supported that configuration. Merlin 16 assembler does for those wanting to program a 16 bit 6502.
