Fixed that for you. ;)

You think he's kidding ... at smj's place, if you ask to use the bathroom he says, "Sure ! Sure, no problem. Can't get there through the hall, it's full. But here, take this path through the kitchen. When you get to the stack of HP-9000's, veer right. Then at the NeXT turboslabs, joggle around the Indy's on your left. A few yards farther you should see some RS/6000's, if you squeeze in behind them you can get through the opening into the bathroom. Just take the Atari's off the seat if you want to pee."

It's actually easier to go outside and climb in through the window :P

That's right, that's absolutely right. Because in fact, hamei's never seen my house. He's seen my fake house, which has some furniture in it, because my real house is packed wall-to-wall with Twiggy-drive Lisas and Macs, Cray-1s, dozens of max config IRIS 3130s, Xerox Altos, original Connection Machines, the fabled prototype "Minnow" desktop PDP10 connected to a Symbolics Framethrower, unbuilt Altair 8800 and Heathkit H11 kits, NeXT prototypes based on the Motorola 88000, a complete set of every SGI desktop machine with clear plastic skins, a PDP-11 running OS/2 that I can't tell anybody on classiccmp about, and I have Gary Kildall and Steve Jobs - both deaths were faked - locked up in my basement.

And they're all in or on awesome purple SGI racks.

That's right chumps - y'all got nuthin' on me.

:D

My sarcasm detector is really confused. Should I go ahead and cancel that 18 wheeler truck + pack of Albanian thieves heading for your place, or shouldn't I? :lol:

If any of them can make a decent tavë kosi or çomlek, and the truck is loaded with rakia, keep 'em coming!

And the IBM zStation... definitely the zStation :D

All joking aside: if I were in the UK, I'd have chartered a truck by now, even if it meant putting the racks in storage until I finish the renovations... sigh :)

This kinda reminds me of the place I was living in the early '00s. At some point there was so much hardware piled that I had to walk like an egyptian to reach the bathroom. Really - the space left in the corridor to the bathroom was really tight! This was annoying enough to make me relocate into a larger place a few weeks later. :lol:

I'll be damned, you know what's buried there:
sabre_ipi2.jpg

It's a hard disk. An 8" CDC Sabre or Seagate equivalent IPI-2 disk. 8-)

I've got one of these (a Seagate ST81154K) in my 4D/380VGX "Predator" rack. This is what it looks like from the back side:
IMGA0372.med.JPG

It occupies roughly half a 19" shelf. This is what it looks like from the front when I pull the shelf out of the 4D/380:
IMGA0368.med.JPG

The front half of what you're seeing here is the dedicated power supply. The keypad can be used to manually power the disk up, change it's status (online/offline it) and manually toggle bad sectors in. I think it was optional because not all Sabres seem to have it. The printout in the transparent envelope contains the list of bad sectors from when it left the factory. The whole thing weighs roughly 30kg and the unformatted capacity is 1.1GB. Internally it stripes data over multiple heads/platters so it's streaming speed is better than it's SCSI brothers which didn't do that.

IPI-2 was the high-end solution back when SCSI was in it's infancy. Some of it's treats (like the dual ported ability) later found their way into Fibre Channel. Dual ported + daisy chaining means there are 4 connectors on the back side.

It's very hard to find useful information about IPI-2 so I'll share two more pictures of how to wire it.
On the bulkhead of the system I have a pair of female 3-row 50 pin female D-shell connectors. Some old SUN equipment used 3-row D shells for SCSI, afaik none of that is compatible but can make it hard to figure out what is what if you run into both in a single haul.

Here the male end of the AMP cable in connected to port 0:
IMGA0364.med.JPG

Unlike SCSI cables, IPI-2 cables have a male and a female connector. The cable connects to the 2nd connector from above (J4). The IPI-2 terminator is on the topmost connector (J3) of the disk. The other two connectors are for an optional second host (the disk is dual ported).
IMG_2301.med.jpg


Like SCSI, IPI-2 requires a host adapter. In the PowerSeries, that's a Xylogics SV7890 full size VME board. The PROMs of the PowerSeries recognize it and can boot from it. You can use fx to initialize it and scan for bad blocks. My 4D/380 boots and runs IRIX 4.05 from the IPI-2 disk, or IRIX 5.3 from a conventional SCSI disk hanging off the IO3.

To accentuate the special identity of the IRIS 4D/70, Silicon Graphics' designers selected a new color palette. The machine's coating blends dark grey, raspberry and beige colors into a pleasing harmony. (IRIS 4D/70 Superworkstation Technical Report)

In particular he has some signed machines, e.g. the 5000th Indy R5K or sth like that, lots of octanes, Indigo2's and 4D series (including my former one) and even some Onyx2 racks.

I've just found some pictures I took a long time ago in his storage area... have a look !

Some of the machines are exposed in the entrance area of the IT department from time to time, but unfortunately most of them are in storage.

Good catch JJ !

@Hombre71: You should browse http://www.bolo.ch, were you'll find information about the museum (machines are exposed in a building of the Swiss federal Institute of Technology in Lausanne) and the Association which takes care of collecting, restoring and preparing the machines. I'm pretty sure they organise visits of their storage area from time to time. If you came in Switzerland and could organise a visit, please let me know... It's been a long long time.
