Just from the fact that everything dies at once, I'd suspect the power supply or connections. - ------------------------------ Date: Tue, 26 Jan 1999 16:28:14 +0000 (GMT) From: Allan Kelly Subject: 3/60 zaphod solution? To: Suns At Home Submissions Hi, I have received a lot of help as a result of my query about using a 3/60 dual-headed with a bwtwo and a cgfour. I have the following facts now: - The cgfour has a color and a mono framebuffer (!) - 3/60s originally ordered as color models had no bwtwo on-board - My 3/60 was mono, and I added the cgfour thus giving me a color and 2 mono framebuffers. - Xsun will by default flip from displaying the cgfour color to the cgfour mono framebuffer when the mouse is moved off the edge of the screen - this behaviour can be stopped by giving the -zaphod option to Xsun. OK so far. With -zaphod i do not get the nasty hiding of the color X display, however I cannot switch to the other monitor either. In 'man Xsun' we have: /dev/cgfour0 This display is available on Sun-3/60, Sun-3/110 and Sun-4/100 platforms. It provides both color and monochrome screens (numbered 0 and 1, respectively by default) on the same monitor by toggling between then whenever the mouse goes off the left or right edges of the screen. OK, that's clear enough. And: - zaphod This option disables switching between screens by sliding the mouse off the left or right edges. With this disabled, a window manager function must be used to switch between screens. Great! Now, what _is_ that 'window manager function'?

Any narrow (50-pin) drive that physically fits should work, as long as it draws no more power (and therefore produces no more heat) than the original Quantums. - ------------------------------ Date: Mon, 25 Jan 1999 05:11:46 -0600 (CST) From: Peter da Silva Subject: Alternate internal drives for SS-1 ?

I've had good luck with the Quantum Fireball. Stay clear of HP SureStore 2000s, they're suicidal. Out of 8 purchased we've lost 6 so far. HP has abandoned that drive division and sold the assets to some holding company, but the drives are still floating around at discount places who advertise them as HP drives. - ------------------------------ Date: Mon, 25 Jan 1999 10:21:01 GMT From: Charles Lindsey Subject: Alternate internal drives for SS-1 ?

I have a SS1+ with internal Maxtor 300MB and Qnantum 1GB, and both are smaller, and use less power, than the 105MB drives originally specified for Sparcstations. Indeed, most modern drives use significantly less power than those older ones. -- Charles H.

Can > I use it anyway over a distance of about 3 meters? I think you've got your T's and 2's reversed :) -- 10Base2 is thinnet coax (BNC connectors), 10BaseT is twisted pair (RJ-45). Most small hubs have a BNC on the back to connect to a 10Base2 "backbone." If yours doesn't, maybe it has an "AUI" (transceiver) connector -- this looks like a game port but most use a slide latch instead of screws to hold the connectors together. Transceivers for 10Base2 are cheap these days because they're considered obsolete. You can most likely get by with using 3 meters or so of 75-ohm cable, because the Ethernet physical-layer design is extremely robust. (I once saw a thinnet segment working fairly well with about 10 feet of 93-ohm cable in it, and the segment was way over the specified 200-meter max length as well.) If I were doing it, I'd try just ignoring the cable's rated impedance and use 50-ohm terminators. - ------------------------------ Date: 25 Jan 1999 05:20:07 -0600 From: peter@Taronga.COM (Peter da Silva) Subject: network question To: Suns-at-Home@tigger.net-kitchen.com From: "Peter J.

To hook your hubs together, get a 10baseT hub with 10base2 uplink port. Here's one: http://www.lantronix.com/htmfiles/prodinfo/datashts/lmr8ta_id.ltx I'm sure you can find other vendors with equivalent hardware. -- This is The Reverend Peter da Silva's Boring Sig File - there are no references to Wolves, Kibo, Discordianism, or The Church of the Subgenius in this document "If you don't have 64 bits, you're not playing with a full DEC." - ------------------------------ Date: Mon, 25 Jan 1999 21:50:08 -0800 (PST) From: Norbert Kirkpatrick Subject: Network question - Sun Sparc and PC To: Suns-at-Home@tigger.net-kitchen.com Hi, I have a sparc5 connected to a linksys hub at home.

Nothing happens when I flick the power switch; the fan doesn't move at all. Both fuses are intact, there are no burn marks on the board at all, nothing is obviously damaged. Does anyone have any ideas as to how to fix it, or know where I can get another PSU that will fit in the box? (must be able to run off 240V, 50hz) Cheers, Pete -- pete hollobon - 01904 655877 - ph116@york.ac.uk - ------------------------------ Date: Mon, 25 Jan 1999 13:12:12 -0700 (MST) From: Bradford Castalia Subject: Suns-at-Home Digest V12 #3 To: Suns-at-Home@tigger.net-kitchen.com The problem is likely to be in the keyboard. I, too, have experienced essentially the same symptoms with a type 4 keyboard. I haven't isolated the specific source, though I suspect a failing diode associated with the LEDs. For awhile I just "bench thumped" the keyboard to get it to shutup, but finally replaced the keyboard and eliminated this annoyance.

On such a short run you just might luck out. If not, maybe you can attach a length of the correct cable type to the end of the old line and, pulling from the other end of the old line, install new wire in place of the old. 10Base2 to 10BaseT transceivers and readily available (as are "converters" for virtually any combination).

I've seen similar phenomenon when the electrolytic capacitors of a p/s slowly died. BTW: if you are not familiar with switching powersupplies please keep your fingers out of them. It is simply too easy to attend your own funeral with these things (even after the mains is disconnected they often keep lethal voltages around for some time) Wilko _ ______________________________________________________________________ | / o / / _ Bulte email: wilko@yedi.iaf.nl |/|/ / / /( (_) Arnhem, The Netherlands WWW : http://www.tcja.nl ______________________________________________ Powered by FreeBSD __________ - ------------------------------ End of Suns-at-Home Digest ******************************
