Re: Some HW questions.

I have some questions about hardware. Basically I am trying to figure
out how to assemble a Hurd victim machine with the least amount of
out-of-pocket expense. I have a collection of random HW which I have
collected over the past several years in my attic, and I am trying to
assemble it into one usable machine, on the cheap if possible. If cheap
means 0/Euros that would be nice.
I suspect the answer to all of them will be yes, but I wanted to ask
before I spend any time on a (literally) bootless effort.
1.) Will it be possible to install the Hurd on a 486DX120, or do I
need a Pentium? What about a 486DX50?
2.) Does anybody have any experience with older Cyrix 586 CPUs? I have
a 200Mhz device which may still work. Linux worked on it reasonably
well before I upgraded.
In principle, GNU mach (which is the microkernel that the Hurd uses)
runs on an i386 with FPU. Since the 486DX has an FPU it should be no
3.) If I have a 350Mb hard drive, but I have a machine which I intend to
use entirely as a Hurd victim machine, will this be enough? That is
to say, can I use this machine only for Hurd binaries, and cross-compile
everything from my Linux machine?
Not everything can be cross compiled. But 350Mb should be enough to
play a bit with the Hurd and compile small packages. The big ones
(the Hurd itself, the GNU C Library and GNU Mach) cross-compile fine.
4.) What's the minimum amount of memory I will need? Will 8Mb be
sufficient? 16Mb? 32Mb? 512Mb?
8Mb is definitely too little. 32Mb should be enough to do some real
work, if you have a reasonable amount of swap (100Mb).
