I have a IIsi without the ethernet card, which means that I dont have a FPU as is it not built in with the processor. Is there any type of Unix/Linux that I can use with it? I really want to run A/UX, but I don't want to buy the card as all the computer stores around here are way over priced. |

BSD might work, but it wouldprobably be slow. I know that A/UX will not work. (it hasn't for me, at least.)Official 68k videographer

The netbsd pages claim that it will run on a 68030 without a math coprocessor. I have run it on an SE/30 and IIci, and the speed is fine for the CLI. The speed is acceptable for X11. This was around version 1.3/1.4.

It just seems that it might be slow without a math copro, I know that it doesn'tmake much difference in OS6/7 unless you have like, an av studio set up or something, but unix likes those sorts of things (FPUs, that is)Official 68k videographer

What about some type of Unix for the Mac Plus? It is running System 6 and only has 1mb of ram.

AFAIK, Minix is the only free Unix which will run on a 16 bit processor. A version is available for the Macintosh, it should run under System 6, though 1 MB may not be enough RAM. As for the math coprocessor issue: this is probably a compiler issue. The compiler assumes that an FPU exists, so it will use it for any single or double precision arithmetic. Yes, this means that an FPU has to be emulated if you don't have it and that will slow things down. OTOH, I don't see why it would make a big difference since I don't see why most Unix software is math intensive (at least WRT floats). But I could be wrong on the speed issue, as I prefer systems with lots of RAM and an FPU.
