The Acorn RISC Machine (ARM). Yes, I know it has a >32-bit bus now, but just talk to VTI (they have the ARM and use it as a >cell, I think): Hmm, 2 people from Apple are talking about ARM. Wonder if that means anything.... OK, where would I get a similarly cheap machine to do ARM development on? (It should cost less than a Sun-3/60, maybe about what a Mac II costs, and maybe somewhere in between what a '386 clone and IBM PS2/80 costs.) It would be nice to get away with 200-250ns DRAMS, for example. Judging from the glowing reviews in Byte, you'd think that somebody would be hot to import some of these nifty U.K developments. But then, whatever happened to the Torch XXX PC, which looked like an serious Amiga 2000/Mac II competitor if ever I saw (a review of) one. -- - Ralph W.

ACORN makes a development system (or someone does), it is cheap compared to other development systems. I don't think you can get away with 200ns DRAM, besides I don't think anyone makes DRAM that slow anymore (at least in 256K-and-up desities). The glowing reviews are justified, but the ARM still has deficiencies that make it less than great for fully general-purpose systems.
