When built into a *system*, with drives and what not...it will be larger of course. The largest "factory" 11/24 system I've seen was two short racks, not much to it. The 11/24 is a very late-model PDP-11, based on the F-11 chip, same as the 11/23. Not fast, but low power consumption and pretty reliable. Dave this is the fault of a big brown fellow watching you. They allllways do. :-( -Dave -- Dave McGuire, AK4HZ New Kensington, PA The 11/24 is a PDP-11/23+ on the UNIBUS. It can accommodate the FPU (chip or board) and the CIS chipset. The size of the unit varies. The largest front panel is 1 DEC system unit (10.5 inches tall) that fits in a 19 inch rack. I managed one of these (a long time ago) that ran RSX-11M with LDP gear. It also ran RTEM-11 (RT-11 Emulator), when I supported RT-11 at DEC Software Services. Several users could work on RTEM-11 at the same time as the LDP hardware was being used. The system never missed a beat! Oh... The entire system ran on two (2) RL02's!!! -Steve

Some musings brought this about AT&T 7300/ 3B1

That very loud noise you hear is every single machine (who is turned on) being not very polite.

3B1s and "old school" UNIX, was Re: [HECnet] US Seller with some interesting stuff

It'd be a pretty nifty addition to a collection, I'd love a really old school Unix machine. I'd not call the 3B1 "old school", but they're lots of fun. I've had a bunch of them over the years, including used one as my main desktop machine for a while in the late 1980s. I also worked at a store that sold and serviced them. If memory serves, the UNIX dialect that they run is SysV release 2. It's a fairly complete SysV implementation, with a nice, low-overhead GUI called "UA", for User Agent. There is no networking, but there's a (rare) Ethernet card for the machine, which was shipped with an IP stack written by Wollongong. The IP stack ran in short spurts between crashes, but you could use it to get stuff on or off the machine. I have two 3B1s now. I like them a lot. They seem to be very interesting systems. If you really want "old school UNIX", find a 3B2. Or REALLY old school, v7 on a PDP-11. Or v1 on a PDP-7. :p -Dave -- Dave McGuire, AK4HZ New Kensington, PA

I know there was the AT&T UNIX PC which was a 68010 + custom external MMU, but there was also a proprietry cpu version I ran into the trap of in a past life. The "UNIX PC" is the 7300, which is nearly identical to the 3B1. The 3B1 has a slightly larger top cover to accommodate a full-height hard drive, while the 7300 will only hold a half-height drive. They are otherwise identical, using 68010s. I'd sure like to know more about the "proprietary cpu" version you're talking about. He's thinking of the WE designed processors that were used in the later units. They were not bit slice but were fabricated using the normal methods. Not surprisingly enough the devices could not even be sold separately. They were ran an appropriately written release of UNIX as native. One of the first applications for them and the later models was in running the first and second generation Electronic Switching Services otherwise known as exchanges. I didn't think he was talking about those at all. Those are the WE32K processors used in the 3B2/5/15/20/etc family. They predate the 3B1 (despite the unfortunate naming) by quite a while. The WE32K family is no more "proprietary" than any other processor. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Oh, trust me, I totally understand. As much as I love SPARC gear I'm down to very little. Just don't have the time or space to deal with that. I leave that to people who do have the time and space like Dave and his fantastic collection of big SPARC iron. -brian On 11/28/2012 10:35 AM, Saku Set l wrote: Well, I can not collect everything and working with Sun equipment for couple of decades has made me to lose interest on them.

Well, I can not collect everything and working with Sun equipment for couple of decades has made me to lose interest on them.
