I therefore don't plan to focus on any particular type of system for an extended period of time, and will migrate from one type of system to the next, as time goes on.
I started a bit like that, except UNIX workstations only. I used to have SUN, HP, DEC Alpha (and SGI of course). But reality gets in the way. There's no way you can have a relevant, more or less complete collection of all these brands. Plus the books, software, spare parts and all the rest that goes with it.
So I decided to put clear limits to my collection:
- SGI only. I sold all my other computers. Well, I have a PC and a MacBook Pro, but the moment these are no longer usable they will be replaced.
- MIPS/IRIX only. No Itaniums, no Visual Workstations and none of the current systems. I may make an exception for an 68K IRIS if I ever have the chance, but I doubt it.
- One specimen of every family of systems. From a collection "completeness" point of view, five Octanes are just more of the same
Since SGI doesn't make MIPS/IRIX systems anymore, and I own a specimen of every family, I'm effectively done adding systems to my collection. If I find a better specimen of a system I already own I might go for it, but the lesser system will have to go. Which is good, because space is finite, and I'm sure there are limits of what my wife will put up as well.
Rule #3 is the most fluid one, btw, because what makes a family? I consider a rack-Onyx2 the same family as a deskside Onyx2, so for reasons of practicality I settled for the deskside. Except I have this 4D/380VGX rack, but also a 4D/440VGX deskside. I have an Indigo2 R4400, a PowerIndigo2 R8000 and an Indigo2 R10K because I consider them different. I "only" have a blue O2 R12K and a purple O2+ R7K, but not the R5K or R10K versions. I once eliminated a deskside O2K with 8*400MHz CPUs and 16GB RAM because I already had an Onyx2 and big compute jobs could be done better on my O350. Yet I still have a Power Challenge *and* an Onyx1. A well, if all the rules were cast in concrete it would be neurotic and not a hobby

Looking forward, I intend to:
* Finish wiring my computer room. That's one thing I underestimated, and one more reason to put a clear limit to what you drag into the house. When I moved into my current computer room, I decided to wire *everything* on all of my ~ 25 systems. All of them have (remotely switchable) power, networking, serial, often fiber network or fibre channel. No maze of extension cords and little junk network switches and scattered all over the place, but everything wired straight to a single equipment rack. This adds up to a total of more than a kilometer of wire in one room... Also, I need many, many adapters, dongles and converters. It takes soooo much time to figure it all out, buy and install it. A lot of it isn't particularly exciting either so I have to put myself to finish it.
* Keep things running for as long as possible. Unfortunately, things do break from time to time, and not everything that breaks can be repaired. This means I need spare parts, I need to know these parts *work*, and I need an inventory to know what I need to look out for and what I don't need. This is not how you acquire parts usually, though. Most of it comes in the form of "please take this cubic meter of junk out of my hands". So I'm always trying to reduce the immense pile of parts stashed away in my attic to a relevant set of spares for my systems and weed out the junk and unnecessary parts.
That's the "boring" part of what I'm up to. Of course I also intend to keep tinkering, run interesting software on my systems, and make the interesting software run in the first place. I want to explore the video capabilities that many of my systems have so I'm slowly acquiring some video gear to make that work.
