Which came first? Apple //gs or Apple ///?

Apple /// came before the GS and the Apple /// is only compatible with 48K Apple II software with an emulator for the Apple ///.

The GS is backward compatible with the II's.

Apple II Geneology

Ok, now can someone tell me why it's //, ///, ][ instead of II, please.

Apple chose ][ for the original Apple ][, ][+, and non-enhanced ][e. When enhanced, ][e became //e. And the Apple /// came out with the forward slash three.

Or simply put Apple made them, so why not?

Then using the slashes and brackets had no more significance than just a kind of marketing gimmick?

I think that the Apple IIgs used the 16-bit version of the 6502 (can't remebr what it is) which had a 6502 8-bit mode for running older software.

The Apple IIGS uses the Western Digital 65816 cpu, which in 8 bit mode enables it to run just about all the original Apple II software.

The enhanced Apple //e, the //c, and the //c+ all used CPU's with larger assembly language instruction sets. The change from the ][e to the //e signified that change. The IIGS was newer too, so it had it's own A.L. instruction set (this was built into the CPU).
