Actually, my cross-build system is not working at the moment, as I have
had problems with several things, and upgrading my ss2 to 1.5 probably
didn't help matters either (from a.out to ELF amongst other things).

And, yes, my sources probably are older than that.

It just hang there doing nothing. There was no activity on the network
at all.

Well, if only I had RISC iX. The R140 had RISC OS 2 when my friend
bought it from the Acorn employee, and he didn't make sure he got a copy
of it. Any ideas of where/how to get it?

I am using an Access+ card that only has 10base-2, so that may have
something to do with that.

OK, I'll try that when I get my build system up and going again.

OK.

Yes, that would explain a lot. Why didn't I see that?

OK, I'll have to try that.

I do have a printer and a switch box with cables, so I could set it up
to work with both my R140 and Risc PC. It's a Canon BJC-610.

What about the FPA10?

I also have an AKA-32 in my Risc PC that I can test out on the R140, and
plenty of SCSI drives, a scanner and a CD-R drive. I also have 4
identical SCSI drives mounted in a cabinet that could let me test ccd
and raidframe if we get the SCSI card working.

Are you also using a 15 kHz monitor?

Since this is an R140, it does have the hires mono output, and I think
that my HP A1097C monitor should be able to handle that. Would that be
interesting?

Excellent. When do you expect that to be available?

One more thing that I noticed is that when I su'ed to root with my
NetBSD/sparc password db files (probably big-endian), the kernel
paniced. Is that something that is likely to have been fixed, or should
I send-pr it?

TIA!
