Later expansion could be as simple as dropping in a new clock and 68030. MMU's or FDHD drives could also be added as one saw fit. If Apple objected to making upgrades so easy, a simple scheme for crippling the board could be devised (omit certain wire paths on the board, a simple jumper could be added/removed, etc). For Christ sake, they are still producing Mac plusses! Also, I question whether everyone will follow the upward path. IBM clones still use 8088's, they are cheap to design and build. The new PS/2 line still uses them. (the Model 30 has a 286 option) 68030 will not push the 68000 machines out for a long time, since even if the costs are equal, the existance of a 68000 machine will allow them to charge more for a 68030. Anyway, you are the second to mention that color might be difficult on the Mac IIv. Given this, we could elimenate it, and produce a cheap B&W video card to be connected to a 12"-14" monitor. I personally hate the 9" things in most macs. Or simply drop to a 68020, instead of all the way down to a 68000. They would probably want to call that a Mac IIc (but I hope not. Ugly flashbacks to a Apple IIc, which they still sell, completely trashing your idea that they would be outdated) Maybe do both, calling the upgraded IIv a IIv 020 (aka the SE 030). Heck, we could continue this and sell a IIv 030, which would still be cheaper because it lacks a coprocessor, MMU, and FDHD drive. Also, from the demo given at the IIcx's introduction, board swaps to upgrade the machine should be VERY easy. paul -- ---------------------------------------------------------------- Graphiti on the wall of civil rights organization in the sixties "There is a town in Mississippi named Liberty There is a Department in Washington called Justice" A more socially aware sort of .sig witting@topaz.rutgers.edu
