I have an Amiga 4000 Video Toaster that I picked a while back with the intention of getting it going. I never have, and thought I'd see if there was any interest in it before I eBay it.

I could be interested. What might you be looking for?

WTF, Steve. There isn't a single 68020 in it. I know, I have one.

By that logic, you might as well call the IRIS 3000 a Mac II, because both used a 16 MHz 68020!

Seriously. Calm down. The only thing the PIC, a Mac, and a NeXT have in common are Steve Jobs. Maybe you should try knowing something before posting.

FWIW the Symbolics was one of two original host systems for the PIC. The other was Sun-3. SGI and uVAX (QBUS) were added a little later.

Mine is a 4-slot P-II, but I don't have a host interface.

Here are a few hasty snapshots I took right after getting it. I bought it as an empty chassis plus an assortment of spare boards. All the necessary parts are accounted for, but I'm not sure how they are configured for a four-slot chassis.

Apologies for the huge size and marginal quality.

Congratulations, you just bought a boat. You have a good start (better than most get), but there's still a long row to hoe, even if you only run Linux on it. Good luck. You're going to need it.

You got me curious so, I opened it up and looked inside. It appears to be something called a HP A4450A Visualize-EG card and it uses the HSC connection. There isn't much on the board actually. Especially for when it was made. I would bet its pretty limited in capability.

The bus it uses is called GSC - general system connect. Electrically it's the same as the HSC found in the server system types.

The EG stands for "Entry Graphics", so yes, it's quite limited. 1280x1024 @ 8bpp, unaccelerated. No double buffering, no overlay planes unless you have an extended memory model. The memory upgrade plugs into the white expansion connector, and makes it somewhat equivalent in function to the Visualize-8. There is also a two-head model with two EVC connectors, which makes use of the unused board area to provide a second full graphics adapter. This is what the empty solder pads are for.

I recently picked up one of these off of CL, but I have a problem with it. I have all the passwords, but the OS seems to be rather... barebones. I have the LIC tape, but I have no idea where I could get a V3R1/2 set. Nice machine though, despite taking forever to IPL. It has 4 320 MB DASD, and 12 MB of RAM in it. Also came with a PS/2 55SX for the console.

I have most of V3R1 on QIC (tapes 2 through 5, missing nr. 1), and a MULIC for a 9404-something from a separate rescue. Maybe we can figure out if there are enough other scroungers out there to pool resources and come up with something more complete? I need some resources (MULIC for starts) for my 9401-P03, which is h/w only at this point.

I also have a bunch of AS/400 stuff on 3480 tape but ISTR it's pretty much all PTFs, SVCs, and CUMs. I have yet to get any of my 3480/3490 equipment together enough to read any of them.

It can. 1.2.1 was the first to ship with a separate install kernel (and boot disk) for ISA bus PCs. In fact the install can be run and completed on VPC6 but I never managed to get a full multi-user boot out of it afterward.

IMO the 750 is a terrible chassis. It's an Intel reference design; I have one as an Intellistation Z Pro. It's poorly laid out, full of fitted styrofoam, ugly, fragile, difficult to service, and massively heavy.

It's nothing like ATX inside.

This is almost without a doubt the culprit. Your PSU is probably fine. Make sure it's actually a resistor that flamed, and not an inductor.

Going back to the original post of this thread, thats actually the reason MS give for killing the IA64 port - reliablity and scalability of x64 is evolving to the mission critical levels needed by industry, therefore making the main selling point of Windows on IA64 somewhat redundant.

I think this is sort of covering up the point that once you take the innate reliability of Windows into account, you're not giving up much by moving from IA64 to x64.

What does a "non proper serial console look like"? Anything from any serial port? You may have to press "1" or "2" at the serial console keyboard during critical times in the boot for it to switch to it.

IME only booting the installation media allows you to select a console at boot time, in that way. If you want to change it on a running system, you have to log in as root and run 'chcons'.

That's good news!

I have several 3/80 motherboards all exhibiting the same fault - there is a wire-wound inductor next to two large SMT caps (I believe these are electrolytic, but have not looked very closely yet), which are very close to the PSU header. It is overheating (and charring) due to an effective dead short on the -12V rail. I haven't yet identified the failing cap(s). Out of curiosity, which two caps did you replace?

The SS20 is one of those machines that has great form-factor karma, like the Mac SE/30 and original Indigo. Please don't ask me to define it any more concretely than that; I don't think I can.

The SS20 is the first unix machine I was ever responsible for. One was a four-head dual SM71 workstation, the other was a dual SM52X server with 30 GB in an SSA110. Except for the SSA110, I've since assembled complete replicas of both of them. I'd actually kind of like to find one of these arrays in working condition, locally, even though it's barely more than a boat anchor at this point. I had a few opportunities in years past but never quite convinced myself to pull the trigger while I had the chance.

I've seen hundreds of drives (with tens of hot-spares, to try to avoid the multiple failure situation) in RAID5 arrays that perform just fine. It's very common on the high end. People who want a little extra insurance will generally RAID0 smaller RAID5 groups (so that each group can withstand a failure, making the array resistant to several simultaneous failures).

I don't think you've looked very closely at what is actually going on with these huge RAID5 systems though. There may be hundreds of drives in the cabinet, but they're configured as multiple RAID5s, with maybe six drives per array... backed by multiple back-end controllers, massive RAM cache, and lots of MIPS to keep the performance up. The Hitachi Freedom, STK VSS, and IBM DS8100 all work this way, as does the EMC Symmetrix (if you've configured it in RAID5 mode).

Part of the problem is that SCSI (and FCAL) performance does not scale linearly with the number of targets. The bus saturates due to command block overhead after five or six targets. I was going to point this out, but it is bus dependent - e.g. IBM SSA does not exhibit this characteristic in the same way. With 1.5 TB drives it is unlikely the OP is using SCSI or FCAL (or SSA!). SATA was my guess, and that's a port architecture that would scale depending on controller architecture/design.

I still wouldn't put nine drives in a single RAID5 group, even if I weren't convinced RAID5 is a dance with the devil in the pale moonlight.

Just so you don't get surprised by this later - you can't grow a RAID5 set by adding a disk to it without rebuilding it from scratch, unless you want your original RAID5 with an unprotected disk tacked on the end of it.

They came from the estate of a former Sun employee in Atlanta. The 100U is complete and will probably run. I am not in so much of a hurry to switch things on that I won't do a thorough checkout first. The 150U is currently an empty chassis, but all the parts are accounted for and so there's every indication it can be returned to working condition as well. I think the 8" SMD drives and 4-track QIC11 are the biggest unknowns at this point.

No, the 3650 was totally separate.

I'm not sure what the deal is with the "U". Conventional wisdom seems to have it that the "U" is a sort of post hoc designator for a 100 or 150 that had been upgraded with a Sun-2 (68010) CPU at some point during its life. However, both of mine are clearly designated "U" on the model tag, without any indication this was added later. They're proper Sun-1 models (with Sun-2 processors); not prototypes. The distinguishing characteristic is the bwone framebuffer, which---unlike the Sun-2's bwtwo---lacks the Sun-2 serial keyboard and mouse interfaces, and does not attach to the P2 bus (no DVMA).

The 150U has the cgone color framebuffer and skyFFP, even.

That looks great and very clean indeed! (More pictures would be greatly appreciated.) The Sun mice haven't changed much over the years, that mouse looks almost identical to the one that I use with my SPARCstation 5 (is it one of those early optical ones like mine?)

More pictures will come eventually. I have a lot of pictures of a lot of equipment I owe a lot of people.

The mouse is optical, but actually bears little more than an outward resemblance to the newer mice. The Sun-1 mouse actually attaches to the same 16-bit parallel port as the keyboard. It didn't become a serial mouse (and thus like all the later mice) until the Sun-2. The pad is also different, though I'm not sure yet if the differences are meaningful.

Yes, but since it is only 1-bit mono you only have to worry about the green for this application, although you might want to wire them all up so you can use it on a color VAXstation.

I am pretty sure the cables are wired differently for color vs. monochrome framebuffers, i.e. the monochrome output is not on the same pin as any of R, G, or B. Somebody should double-check me on it, though.

I have located IBM's QIC tape option for the PS/2. If I recall, 1.3 came in both floppy and tape form, right?
What are the chances I can rebuild a distro tape?

That depends on what you expect "distro tape" means.

Anybody on the board have direct experience with Intergraph Clipper workstations?

I have recently acquired one which is being contrary, and it'd be nice if there were somebody I could chat with about what it OUGHT to be doing. Basically it's switching on, but otherwise showing no further sign of life. It's possible I have something hooked up wrong, I suppose. I briefly had the monitor in sync with no picture, but now I can't even get that much (it may have been a fluke to begin with).

FWIW it's a 2700-series.

Okay, that's good to know.

What do you know about the monitor requirements and connector pinout? It has a 13W3 and the source I found suggests it's separate (composite H/V) sync, with the same pinout as a Sun. But I have no reason to believe this is necessarily accurate. I have another (older) 2000-series on its way, that looks like it has a 5W5 video connector, which I've never seen anything similar to before, but suggests it may use separate H and V sync, in which case I'm not going to get anywhere with the Sun cable.

Is there a way to get it to respond on a serial port? That would tell me at least a little until I work out the video signal requirements. My initial attempts got nothing, and I'm not entirely sure I didn't dork something up while I was sucking dust out of it (it was really bad).

I have the keyboard and mouse (and a tablet), so that's not a problem.

probably... if I had a 'scope, and any indication the system was getting far enough to show the PROM menu.

I just did a quick inspection of the framebuffer board artwork - looks like the 13W3 is wired with (at least) pins 2, 4, and 5 (in addition to A1, A2, and A3) which, if they are carrying separate H and V sync, should be feasible for successful combinatoric testing. I'll have to think about how to come up with a convenient test rig for it, though. Perhaps if I stare at the Fry's parts shelves for long enough, something will become apparent.

The fact that pins 2, 4, and 5 are wired at all strongly suggests my information about the Intergraph 13W3 pinout is bad (or at least not applicable to a machine of this vintage).
