Info Needed: Motorola EXORcisor 6800 System

I was using a Kontron development system then so I didn't use the EXORcisor firsthand. As I recall, it had a backplane that accepted cards from Motorola and a few 3rd-party manufacturers (cpu, memory, serial ports, etc). The cards had dimensions similar to S-100 but were 86-pin or something like that, and of course the bus incorporated more 6800-ish signals, like the E clock signal used to synchronize bus events. The idea was that you could run the EXORcisor itself as a general-purpose computer (monitor, editor, assembler, Basic, and so on--running on top of a proprietary Motorola OS that I can't recall) and you could stuff in any special boards you were developing for your application and so integrate them into your software development. When you had the code debugged, you'd blow an eprom, pull the boards out and stuff them into their own cabinet, insert the eprom, and start up your embedded system independent of the EXORcisor. One interesting thing was that many of Motorola's standalone (KIM-like) single-board computer "development kits" like the "D2" had the same EXORcisor bus connector and you could easily mix-and-match those boards with standard EXORcisor cards. I have a couple of EXORcisor cards somewhere (a Burr-Brown D to A card, some memory boards I think?) but no EXORcisor and no documents. So if you have documentation I'd like to take advantage and get copies of the relevant schematics, etc. I also think I have a couple of ROMs containing Motorola Basic that would probably work if plugged into an EXORcisor memory card. The system you've got probably sold for upwards of $20K back then. This was state-of-the-art professional gear, so admiration and respect are warranted :) Arlen -- Arlen Michaels amichael(a)nortelnetworks.com

OT - power supplies

by jim＠calico.litterbox.com

Thanks to all who replied. I was concerned that if the PSs are really pulling 7 amps each I was going to run out of power really quickly in my computer room, which is fed by a single 20 amp circuit. However, since they're not, my 3 soon to be 4 computers, tv, and laser printer will (hopefully) all peacefully coexist. Again, thanks. :) -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

HP9100 EHT oscillator transistor

The >2N1701 is only rated at 60-odd volts, which the BF259 (or any of the >other transistors I've tried) can stand trivially. Well, a 2SD350 or 380 are fairly common HOP transistors, they will certainly run at line freq, I don't have a data book handy, but they have Ic ratings of well over an amp. 2N3055 might work too, though I'm not certain it could handle the frequency. They all have TO3 cases though, so mounting it might be a headache. If I can dig up a data book in this mess I'll see what else I can come up with.

Always has been. It includes SunOS, Openwindows, and tools. Real developement ended on SunOS 4 about 7 years ago, 4.1.4 being the last released version about 3-4 years ago. Also called Solaris 1.1.2. Yes, the Solaris moniker was retrofitted to the SunOS 4 stuff. SunOS 5, also called Solaris 2, is running rampant as we speak. the Solaris 7 thing, well, we figured that was just to get a bigger number than NT 5. course, now its windows 2000. Solaris 7, aka 5.7, aka 2.7, still returns 5.7 in the uname commands to ensure compatibility with scripts, etc. This is even on topic, sort of. The Sun announcement of what would become Solaris was in 1987. Kelly

SunOS -- was: Evans & Sutherland Y2K scrapyard heads-up

by dhansen＠zebra.net

SunOS and Solaris were seperate creatures up until about Solaris 2.4 and SunOS 5.4 when they began merging the two into one entity. As for the numbering scheme that is definitely weird. It's advertised as Solaris 7, yet in the code it comes up as 2.7. Guess their marketing dept. had an afterthought about it. david On Tue, 22 Dec 1998, pete(a)dunnington.u-net.com (Pete Turnbull) wrote: >On Dec 21, 23:04, Aaron Christopher Finney wrote: > >> Indeed.

I wasn't sure what was meant, but what you describe is what I usually assume as well (though SunOS != Solaris, according to Sun -- they seem to have changed their marketing position recently, to say nothing of the numbering scheme). -- Pete Peter Turnbull Dept. of Computer Science University of York

Southern California TRW Swap

by jpl15＠netcom.com

To any of us who will be in or near the SoCal area this Northern-Hemisphere Solstice proximate weekend: Greetings. The TRW Amateur Radio Swapfest will be held on 26th December at the TRW facilities in El Segundo, Cal from 7:30 am til 11:30 am.. 405 (San Diego) freeway to Rosecrans exit, Rosecrans west to Aviation, Aviation south (turn under the railway bridge) one block and it will be on your right. The closest intersection is Aviation and Marine. E-mail me if more info is needed. If any interest, those who Show Up will be invited to an after-swap luncheon whereat we can gloat/whine over the day's 'catch'. Marvin and I will be in spaces J-21 and -23. Cheers John PS: WX is clear, crisp and beautiful; not like last time...
