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

Apple II

Was the Apple //gs released AFTER the Apple ///? or before?

Also, are both of these machines backwards compatible with Apple ][ software?

Apple /// came before the GS

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.

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

RE: why it's //, ///, ][ instead of II

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 slash and the

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.

Apple IIGS CPU

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.

Well. . .

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).
