OK, the 840AV has one of those mini-centronics-style connectors on the rear for the network transceiver. I have some "Asante FriendlyNet Thin Adapter"s that will mate with this and work -- for a 10Base2 network! The Asante box has an RJ45 on the rear. The cable that mates to the network connector on the 840AV has that funky mini-centronics on one end and an RJ45 *plug* on the other. This choice of connectors -- and the "Thin Adapter" moniker -- suggests that I could plug the RJ45 *plug* end of this cable into a hub directly? Is this true? Or, just wishful thinking (and an unfortunate choice in connectors on Asantes part)?

I have a few of those. No, sorry, the RJ45 isn't a 10baseT connection. It's more like an AUI connection, but with a different connector. -- Pete Peter Turnbull Network Manager University of York

VAXen RULE! (Was: Microkernels)

That was implied, but I'll reiterate: What platform (includes implementation) do you think was really neat and why. P.S. The VAX had problems quote was mostly to illustrate that all computers can be dissed. Somebody asked why: mostly implementation. The original VAX was very instruction-heavy, but DEC did it right and started offloading to "heavy microcode" (read emulator). However, some VAXen designed in 1992 were still using Q-bus for main expansion. 'Nuff said. Implementation. There are other little bits like this.

Troubleshooting SPARCstation LX

When it can't find the keyboard, it >switches over to ttya for input and output on its own. The point I was pontificating and pondering as a possibility presumes, perhaps, prior persons preselecting port 1 or 2 for the console, and since the OBP was directing output there, you wouldn't get output on the screen, which was the initial problem in the post,

How CPU's work (was Re: Hi, I'm new...)

by c.murray.mccullough＠gmail.com

Patrick Finnegan writing on Chuck Guzis' commentary: { I like that analogy... and in order to add on the rooms, they had to get rid "of some of the more "interesting" parts of the original, like the "POP CS" instruction.} {Some are a horrible nightmare: the intel chip for example, and to a far far lesser degree, MIPS.} I quite agree that the 'shack' expanded into the current 8086 conglomeration but we must consider its success. It's practically the 'only' thing left for the masses to experiment with. Those of us still in pre-PC era(well, trying to stay there - getting harder and harder these days!), and I do enjoy fiddling-around with my Coleco ADAM and coding the Z-80, can only wonder and ponder, what-if... Keep on computing! Murray :)

End of PeeCees? (HIJACKED TO "QIC-150 tape questions")

by compoobah＠valleyimplants.com

> Didn't you get the memo? > >"The Network is the Computer" AHA! Back on topic. They sold you both, and it worked, and it was pretty open-standard. Another Sun-(kina-sorta-related) question - have a Sun labeled Archive 150MB QIC, and I was trying to read some of the CV tapes that Josh had, but I was having big problems with errors and the tape going slack. I've been trying to figure out what's up, as his QIC24 60-meg is reading them just fine. Any ideas? (the roller is in good health)

IDE doesn't suck

Anyone want an MDX-SIO2 STD-Z80 bus UART technical manual ?

by Jason.Armistead＠otis.com

Hi During a clean-up, I came across one copy of a Mizar Digital Systems / Hamilton Standard Digital Systems (aka Mostek) MDX-SIO2 board for the STD-Z80 bus. If anyone wants it, sing out or I'll be throwing it out. Cheers Jason

Scouting Mission

by compoobah＠valleyimplants.com

>The terminal style IRIS must have been more or less same height and >same depth, but it isn't as wide as I think it has less space for >boards. I have never seen the rack, but I have also seen it mentioned >in the Old IRIS FAQ. No, about the same depth but it didn't have the drive bays in the top so it was noticeably shorter. It could go on the desk (terminal system, not rack).

IRISes (WAS Re: Scouting mission)

by compoobah＠valleyimplants.com

> I've already aquired a couple of Personal IRISes, an Indy and an Indigo2, so >I'm all set on the playing-around-with-IRIX front :) Aahh yes - but IRIS x000 don't run IRIX, they run GL2-W with the MEX windowing system. Verry different, verry interestink... Might I suggest 4D1-3.3.2 (IRIX 3.3.2) on a PI - 4D1-3.x had a NeWS based windowing-system, among the few NeWS systems released standard (I'm not even sure which SunOS Sun's NeWS came with - SunOS 3 was SunView, SunOS 4 was OpenWindows (NeWS+X11, but not strictly NeWS). IRIX 5.3 should go on one machine (5.3+XFS should you be lucky enough to find it). This will allow you to run COFF binaries. The other one (R4k) should run an IRIX 6.x release. The 3000 with GL2-W3.6 would fit in quite nicely...
