[munch .unch ..nch ...ch ....h .....] I quite sure this has been hacked around before, but here goes anyway. 68020 vs. 32032 which is better to base your system around?

go ahead bug, make my day. I like the 32032. Simpler chip (less transistors == more reliable (?), MUCH more orthogonal instruction set (better -> faster compilers, faster, more compact object code), 32032 available now (6mhz version), along with fpu and mmu. Now, when the 68020, motorola fpu and advanced mmu become available, the fanciest system you could build with motorola parts will probably outperform the fanciest system you can build with (currently proposed) national parts. You will pay for that extra bit of performance through the nose though. National seems to have decided to do simpler components optimized to what they consider to be the average use, rather than fancy parts that can be adjusted to optimize your particular use. In exchange, national was able to produce their parts, while motorola is still dreaming. No connection to mot or nsc, always my own opinions -- Kurt Guntheroth John Fluke Mfg.

The NS32032 is available *now*, which is more than you can say for the MC68020. Don't hold your breath for the 68020's memory management and floating point units either...has Motorola announced when they should be available?

I believe Motorola has said that the support chips for the 68020 will be available "several months after the 68020". In other words, just this side of never. And as Jan Gray reported, 32032's are available *now*. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry

[] I would like to see some benchmarks comparing the two processors, both with and without floating point operations. Also, has anyone heard of any enhancements or new chips by NS to combat the 68020? Sean Casey UK Mathematical Sciences
