- The new PPC Amigas will not run *any* of the old software, unless AT is
- able to produce a 68K emulator on PPC (such as by dealing with Apple). If
- that route is taken the emulation can emulate the old OS features as well.
-
- People in this discussion are saying that since the move to PPC breaks all
- old code because of hardware, why not take the opportunity to advance
- the OS at the same time? That way code is broken only once, rather than
- twice - once by hardware and then later (or earlier) by software.
-
- I'm just not worried about games. If there is a hardware platform that
- is sold in good quantities, and whose owners are interested in buying
- games, then games will be written for it. Games usually have a short
- lifetime compared to other software, so can move to a new OS/CPU without
- too much pain in the industry.
-
- I am more concerned about the other kinds of applications - paint programs,
- music programs, word processors, databases, compilers, editors, etc. They
- can survive if they are not written in assembler, since they can be
- recompiled for the new CPU. Having to change them to use a somewhat
- different (but philosophically the same) OS is some work, but probably
- not that much.
