Do I need any special drivers? - What kind of SCSI floppy drives are available at what cost? Would a floptical work?

We've succeeded in getting the printer working on ttyb; ttya now won't work with a printer, tip to a modem, or getty on an ascii terminal. Questions: 1. How do I conduct an autopsy on /dev/ttya? There were no complaints from the machine when it rebooted. We have no hardware manuals for the machine. 2. Is it likely that I can revive this port with a relatively simple home repair? The salvage value of the machine is low enough that sending it away for expensive repairs may be unwise. 3. Is there a way to prevent future lightning damage? The line >from the 3/60 to the printer is ~10 feet long. In the past, I had lightning problems with ascii terminals on long (~100 foot) cables that ran partially outside the house. Inexpensive serial-line surge protectors on those lines didn't help. I've never before had a problem with a short line inside the house, but I have noticed that this machine reboots frequently during lightning storms. Thanks.

I *think* they have to be installed on a tray just like the internal streamer, but I'm not sure about this. Can someone out there enlighten me? Furthermore, are there any hardware manuals around concerning this particular machine? I don't have a description of it. Oh, one last thing: I have a scsi-adapter without an external interface and I'd like to exchange it for one with it so that I can add external devices like CD-ROM, Tapes, Streamers etc. Is this possible or do I have to get an additional scsi-adapter and how much would such a beast cost?

To: sun-386i@ssg.com, suns-at-home@orchestra.ecn.purdue.edu, (I am not on these lists yet, so pls. CC: replies to cz@silver.lcs.mit.edu, otherwise I won't get them. Thanks). [cz is on SaH now. --ed] When last we left him, CZ was wondering why the new disk drive didn't work. Suggestions were made to set it to ID2. After trying this, the disk was READABLE. Great. So, I started to install the system, and stopped when it asked for disk 11. I didn't have disk 11. Oh great. Fortunately I have the OS on tape, so I think "Well, I will just start what is on sd2: in single user mode, mount the second floppy, and change the Install file in /etc to point to the tape. Of course I will have to un-write-protect the floppy (screams of OH NO come from the rafters), but that shouldn't be a problem. So, I boot, change the file, rewriteprotect the floppy, shutdown, and try to boot off of the floppy disks. The first disk loads, then asks for the second disk. After inserting disk2, I get the friendly message: Wrong Diskette. Please start over (SunOS halted) Great. It appears that by modifying the disk, I changed some magic number, and now SunLoss Install won't take it anymore. Typical UNIX. The disk appears to be ok (a fsck on it while wprotected turned up ok) So, I am asking the net for any advice. Specifically: (1) A spare set of SunOS 4.0.1 disks that I can buy/beg off someone (2) Someone in the Washington DC aera to whom I can drag this disk to for a rebuild. (3) Info on how to get a set of install disks from Sun (4) Info on how I might be able to fix the second floppy that I have (rewrite the magic numbers, chant, etc) and get another disk 11 (5) Info on how I might be able to read the SunOS tape I have (no, I don't have the sun blessed floppies that one appears to need) Currently I have a Sun386 that will boot off the SD device, but only in single user mode. When I try a full boot, the system clears the screen, displays the pointer for a second, and sits there forever (or untill I reboot). It looks like some of the OpenWindows programs are on disk 11 (which I still don't have), but I can get into the shell and run command line programs. ANY help would be appreciated.

I've just joined this mailing list and I'd like to take the opportunity to ask if anyone out there has a keyboard cable for a sun386i with a cg3 (color) framebuffer? I have a 386i/150XP with a 19" mono monitor and just got hold of a used cg3 I want to use. The guy I bought the cg3 from had given the cable to someone for use on a sparcstation. As the Sparcstation doesn't route the keyboard signals in the same cable this guy just cut off the keyboard cable (Sigh!). Has anyone tried to use the second serial port on a 386i, /dev/ttyb? I know it doesn't have a connector or any drivers/receivers but the chip is there. I've been thinking of adding a MAX-232 driver/receiver and a connector to get another serial port. Also I've been thinking of replacing the 386DX with a Cyrix 486DX or the new 486DRU2. Anyone done this? Will the cache in the cyrix chip work in this machine? Anyway I'm quite pleased with the machine. It has two disk, about 500M disk space, a 1/4" tape streamer, runs x11r5, olvwm, lucid emacs (19.6). I have a brand new Apple LaserWriter Select 310 (Postscript) hooked to the parallel port. Runs TeX, groff. I also have an Apple LCII and a short ethernet between them. Runs netatalk (AppleTalk) on the sun and uses it as an AppleShare server and LaserWriter printer server. And it beats the socks of the 3/50:s and 3/60:s. It's is faster than our old 3/280 we had at work on raw CPU. Still I think intel processors stinks. I had to have a machine I could run a very specific cross compiler on. It was dos (yeach) only and I didn't want a pc. Otherwise I guess I would have bought and old 3/60. I'm glad I didn't.

To: suns-at-home@orchestra.ecn.purdue.edu (Suns-At-Home Mailing) Hallo, yet another question: My machine here apparently runs on SunOS 4.1.1, when booting it also displays (GENERIC) #1 or something to that effect. Which patches do you recommend/do I need to avoid running into bugs when starting to use the machine? Thanks a lot Soenke ------------------------------ End of Suns-at-Home Digest ******************************
