Birdsall" Subject: 3-Chip SIMMs in Sun 3/80 To: Suns-at-Home@tigger.net-kitchen.com Well, this is interesting. If you post this question to comp.sys.sun.hardware, you'll get a dozen replies that it doesn't work and even explanations of what the problem is, and *nobody* who has done it successfully. I never questioned that because I couldn't get three-chip SIMMs to so much as pass the ROM diagnostics memory tests in my 3/60. Here, two out of three replies say it does work! So I guess the real answer is: you can try it, but the outcome depends on the tolerances of the particular units involved. I will update the entry in the Sun Hardware Reference. --James [Yeah, I thought this was odd, too.

Notably the 3/60 series. I cannot remember whether a standard 3/60 will take 4MB SIMMS or if there is a mod. If a machine will take 4MB SIMMs, then a 3 chip 1MB SIMM should get enough refresh cycles to be OK.

I shutdown the system, pulled the box apart and found... A Wangtek 1/4 inch tape drive (Model # 5099EN24). The PCB is an Emulex board. Most importantly, this contraption is documented in the Sun Hardware Reference (All praise James Birdsall!) so I think I can figure it out. Next system outage, I'll re-install the thing and see if it works. [Alan's earlier message read, in part: "I have what I believe to be an Archive 150MB 1/4 inch tape drive in an external box. (tape drive with non-SCSI connector (QIC?), attached to a PCB with a 50 pin SCSI connector on it). This is connected to my Sun SparcStation 1+. Unfortunately, I got the tape drive "as is" and it didn't include any documentation. There is a SCSI conflict when I have the tape drive connected but things are fine without it. I pulled the PCB board and it contains a few different jumper blocks but none of which are immediately obvious as SCSI ID jumpers."

To: Suns-at-Home@tigger.net-kitchen.com Hi, I've tried to setup printing on a SUN Sparc LX running Solaris 2.5. All messages seem to be what is expected, yet nothing prints out. The printer is connect to port B. A couple months ago I recall a patch necessary for printing. Does anyone know what patch I need? Also, the printer is an HP Deskjet 500. Does anyone have any experience, or know how setup solaris to use this printer? Thanks in advance, anthony anthony@mksrc.com - ------------------------------ Date: Thu, 17 Oct 96 06:52 EDT From: adh@an.bradford.ma.us Subject: Serial port/modem problem To: Suns-at-Home@tigger.net-kitchen.com From: wp@pocs.com (Wolfgang Polak) I've been running UUCP on my Sparc station IPC under SunOS 4.1.1 for years without problems, dialling in and out of ttya/cua0. After upgrading to SunOS 4.1.4 I can't seem to get the dialin/dialout on the same port working. The problem I see is that whenever I turn off the soft carrier on ttya the device "disappears", i.e., any open on ttya or cua0 fails with "no such device or address" (ENXIO). That means that getty, kermit, uucico, tip all fail to talk to the line. Even ttysoftcar fails, so the only way I found to get the port back is to reboot with ttya turned off or declared local in /etc/ttytab. Any idea is appreciated. -wp i followed celeste stokely's procedure exactly, with one difference: instead of making cua0 to dial out, i tried the sysV/bnu trick of adding ,M to ttya in Devices and bracketing my chat script with \M at the start and \m after the connect token. this allows the port to be opened in clocal mode, then unsets clocal for the connection. - ------------------------------ Date: Mon, 14 Oct 1996 20:29:45 -0500 From: Matt Crawford Subject: Suns-at-Home Digest V9 #38 To: Suns-at-Home@tigger.net-kitchen.com The problem I see is that whenever I turn off the soft carrier on ttya the device "disappears", i.e., any open on ttya or cua0 fails with "no such device or address" (ENXIO). I dimly remember something like that happening after an upgrade and I *think* the cure was to set in the EEPROM ttyb-ignore-cd=true ttya-ignore-cd=true I see that I have ttya (my printer port) commented out of ttytab, and ttyb (the modem) not marked "local". ______________________________________________________________________ Matt Crawford matt@severian.chi.il.us Maxwell House Daemon - ------------------------------ Date: Wed, 16 Oct 96 10:21:54 PDT From: wp@pocs.com (Wolfgang Polak) Subject: ttysoftcar problem resolved... To: Suns-at-Home@tigger.net-kitchen.com Finally, I figured out why my tty port became inaccessible after running "ttysoftcar -n" on it. All I needed to do was to take the RS232 line tester (the thing with the red and green LEDs) out of the modem cable. I have no clue why this should make a difference - maybe the LEDs produced enough of a load to make the driver think that something is wrong. The lesson learned is that these testers are not as benign as one might think. Thanks to Matt Crawford and Fred Lakin for suggestions to my original post. -wp - ------------------------------ End of Suns-at-Home Digest ******************************
