RISComputer 3240

Unread postby miod » Tue Sep 24, 2013 12:29 pm

To (hopefully) enlighten everyone workstation-savvy, and give us a sunshine from real life and Linux rants (oh, wait, should I have said ``GNU/Linux''?), here are a few pics from a venerable SGI cousin machine I have saved from oblivion a couple weekends ago:

A deskside chassis...
Image
Image

... with lots of slots: 6 for memory, 4 for ISA boards...
Image

... and a good old R3000 running the show...
Image
Image

... with 3 memory boards of 8MB each. Spares, anyone? These can't probably be found anywhere anymore!
Image

And for you mobo lovers, here is the naked thing, front and back. Find the blue strap on the back side!
Image
Image

Sorry about the blur on some pics. I'll try to shoot better pics eventually, and will replace the images with the better versions.
It still runs RISC/Os 5.4 happily.

Always seemed like fine, if somewhat generic, RISC machines to me. Nice to see one again.

I used to have some MIPS workstation brochures, (along with other marketing like an Ardent Titan poster). It was around the time that Sun 3/80s and SPARCstation 1s were in use in offices I would visit, around 1991 I guess.

I seem to remember that MIPS came out with a machine based on the R6000; did that use the same processor slot as the machine you have?

I also see that it has a Fujitsu SCSI chip, only the second one I've seen. I have an MB87030 module that plugs into pin headers on a VME industrial computer.

I wonder what the option slot beside the PROMs is for? graphics?

I have no idea. Not sure if the R6000 and cache would fit within the R2000/R3000 cpu board size.

That particular chip was also used by the HP9000/300 and HP9000/400 series, as well as the OMRON Luna systems and the Sharp X68000.

Fun!
(And yes you should have. ;) )

As miod says, my HP9000/350 has a Fujitsu SCSI chip.

Good find, that looks like a fun system for sure. Is it me or it the CPU board sagging?

Interesting to see that the packaging of the CPU is different from the R3000's found in SGI's (ceramic Flat-pack versus ceramic PGA).

Very cool. Any idea of what the original purpose for this particular machine was, and how long it was in operation?

http://en.wikipedia.org/wiki/R3000

This chip was used very widely, including on the Sony NEWS workstations. The R3000A was even used in the original PlayStation (clocked at 33 MHz).

It is. Must be the weight of the bits flowing through it... :lol:

The DECstations used QFP processors as well. I guess the desire to have the processor socketed was what led SGI to use a PGA variant.
The PlayStation uses a custom chip (from LSI Logic) with a CW33300 core, plus coprocessors for geometry transformation and image decompression.
The core is not simply a R3000A: the latter has no internal cache. The MMU is also different.

I'm confused. If this is the 'hinv' output of my 4D/440 VGX, am I supposed to believe the L1 is *external* ? Or, did NEC (and IDT) simply package an R3000 core with cache on a single chip for SGI?

I vaguely remember that some specifically tuned code would run faster on an R3000 than on R4000, despite the much lower clock, because of the larger CPU cache. R4000 has only 8+8KB cache (16+16KB on later models). But it's been a long time ;)
