Re: No graphics out from Indigo2

A bad CPU wouldn't send the signal for the hard disk to start, would it? If your disk is jumpered to auto-spin, the mere application of power will spin it up (sometimes after a delay). If it isn't, it will not spin until a "test unit ready" command is sent to it by the PROM, which would i...

Re: What extremely rare (non-prototype) computers do you wish you could find?

On behalf of one of my friends i am still looking out for a Sun 486i Apache Ah, but these would fit into the "prototype" category. I'd love to see one too, if only to confirm this is not an urban legend, everyone's source being "I've heard of..." or "a friend of a relative ...

Re: What extremely rare (non-prototype) computers do you wish you could find?

Are we all writing our letter to Santa? Here is the list of the non-prototype systems I wish I could get my hands on eventually (but probably never will): ⋅ MIPS-based machines: ⋅ any Sony NEWS ⋅ MIPS Magnum R4000 (not the R3000 one) ⋅ any NEC RiscStation (ARC...

Re: clang 64-bit MIPS enabled in OpenBSD

I've just found a commit in the OpenBSD tree, related to enabling MIPS support in clang. However, IIRC, clang wasn't yet ready for outputting MIPS3 nor MIPS4 code. Has that changed? If affirmative, I consider this a great achievement, as it would mean clang would run on SGI hardware... Anybody has ...

Re: Getting crimson set up - Hard drive issues

The VME SCSI board is a rebadged Interphase 'Jaguar', and (possibly ?) high voltage differential SCSI. One has to be extremely careful with Jaguar boards. Not only do they exist in both single-ended and differential flavour with no clear difference between them, but they also take daughterboards fo...

If you're willing to cut your fingers when tinkering with the machine's internals, the Quadra 650 is an extremely reliable, compact system.

Be sure to compile with _XOPEN_SOURCE defined (to get SCM_RIGHTS among other things), and use _XOPEN_IOV_MAX for IOV_MAX.

Just pick err.h and err.c, errx.c, verr.c, verrx.c, vwarn.c, vwarnx.c, warn.c, warnx.c from any *BSD libc.

Re: Volunteers for test: print NaN in MIPSPro/gcc

I have just checked R8000, cvt.d.s of NaN is not implemented in hardware and traps, and thus I get the proper sign.

Re: Volunteers for test: print NaN in MIPSPro/gcc

Running your test on an R10000 under OpenBSD here, I get the same results as you do - the float nan are printed as positive. From http://man.openbsd.org/printf.1 i read that openBSD is supposed to shown the sign of the NaN, so this indicates a hardware conversion in the Processor itself... This is ...
