Can you explain how they are "simplier than RISC"? I have not seen anybody make
this claim to date.

Java Architecture is based on a stack machine, or
a zero address machine. I won't bored you with details, but
The Java chip organization looks more like the inside of a
HP calculator than does a RISC microprocessor.

I know all about stack machines. FWIW, they have been around for a long, long time. There just has never been a major commercial success of a stack machine. I would not describe a stack architecture machine as "simpler than RISC". While it may appear simpler from an instruction standpoint (lots of 1-byte instructions) that does not make it "simpler than RISC", since it takes more work inside to manage a stack architecture.

On add-in processor cards - I agree that there is somewhat more of a market for business uses than for home use. However, add-in processor cards have never been a big success in any case. Apple cards for PCs. PC cards for Apples. CP/M cards for MSDOS. MSDOS cards for CP/M. Fancy math cards. RISC cards for PCs. None of these have ever gone over big, and I doubt that Java cards will either.

By the way, you mention the low cost of Java processors - has anyone even announced prices of Java processors? And, given the targeting, will these even be suitable for desktop use? I question whether they will even be suitable for NCs. Maybe they will be suitable for light switches, the original Java application...
