Craig roll asks: > Are there any differences between the //+ instruction set > and the //c intruction set? Yes. The ][+ has a 6502 microprocessor chip. The //c and the enhanced //e have a 65C02, which has something like 20 additional instructions. > If so, is this why certain (non-graphics) software is beeing offered > for the //c and the //e but not the //+? Only partially. There are other hardware features of the later machines, including the full keyboard, that make developers want to shun the ][+. > The AE accelerator card [Transwarp] advertises a "65C02" board.

The Transwarp will give you all the new instructions, and it'll make your machine run 3 times as fast. It will not give you double hi-res graphics - for that you need an extended 80-column card.
