In particular, has anyone written the print spooler >data filters ... graphics files for ... >Laserjet-plus or any dot matrix printer (Epson etc) that use byte encoded >bit images and would be willing to share their source code? We have written a graphics output program for the epson JX80 color printer (which Epson has since canceled) that produces horizontal or vertical color prints from a Sun 3 raster file. The program also will work with the QMS KISS laser printer or other epson compatable by removing the color selection codes. The program is fairly small and illustrates byte encoding of raster image files with aspect ratio correction and color balancing on a 1280x900 image with 3 - 5 levels of RGB. If you would pass this on to Chris and see if it is still needed, I'll send the source. I'll need a better address though, preferably relative to mcvax.

Two of those components were either out of production or difficult to come by. C413, a 2.2uF, 100V, AL Electrolytic capacitor, rated @ 105 degrees C, is manufactured by, and sold thru distributors of, Elna. CR406 can be replaced by Amperex diode BYV 96D. Between its cathode and the hole on the PCBA where the cathode enters, install R541, a 33 ohm half watt resistor. There are other video problems (such as warped vertical) whose solutions are yet to be found. ------- ----------------------------- Date: Wed, 7 May 86 21:03:41 EDT From: Mark Weiser <mark@mimsy.umd.edu> Subject: dumping disks before upgrades. Just let me note that in addition to the many sympathetic mail messages to sun-spots about my comment, I got lots of direct mail from people who were glad I spoke up. Only one person, a person on sun-spots, said they don't mind trashing their disks every new Sun release. -mark ----------------------------- Date: Mon, 12 May 86 17:15:58 pdt From: dcmartin%ginko@BERKELEY.EDU (David C. Martin) Subject: posting to mod.sources I posted some sources for program I wrote to manipulate icons (i.e. trim, move, show) and a program to show arbitrary sized pixrects using a window. I thought some of the people who read this group would like a pointer. dcm ----- David C.

Two questions: 1) Does 4.3 BSD actually implement Courier; and 2) if so, has anyone implemented Courier on a Sun, so as to talk to a VAX?? Any info on this subject would be appreciated. daven (Dave Nelson) arpa: daven@lll-crg.arpa uucp: ...{seismo,gymble,mordor,sun,lll-lcc}!lll-crg!maddog!daven ----------------------------- Date: Fri, 9 May 86 16:42 EST From: ONDRECHEN%northeastern.edu@CSNET-RELAY.ARPA Subject: SUN3 as a multiuser number cruncher I am new to Sun Spots. We are thinking of purchasing a SUN-3 (with 8 MBs, FPA, 16-channel multiplexer, and 260MB disk). I must meet the needs of 5 groups of CPU-and-RAM-hungry users. The new system will partially off-load an oversubscribed vax 11/780 which belongs to a larger community. Some of our programs occupy 2-3 MBs of main memory and run for 0.5 to several CPU-hours on the vax. Does anyone out there have experience using a Sun-3 as a multiuser number cruncher? Can this be done on a Sun-3? Can this be done in the absence of a batch queue? I would appreciate your advice and wisdom. (As you may have gathered, our budget is limited, and I do not yet have experience with either Sun or unix.)

We want to be able to do network backboning using suns. The network communication is 56kb DDS lines. We would like a Sun to be able to handle four of these. Naturally, hardware support is essential. Does anyone have knowledge of hardware we could use? Does the Sun DMA rs-232 8 line card hold in promise for this application? Thanks for any help. -mark ----------------------------- Date: Mon, 12 May 86 20:24:29 edt From: rti-sel!dg_rtp!rtp41!dg_rama!stuart%mcnc.csnet@CSNET-RELAY.ARPA Subject: using dump over a network - help! We have three Sun2's in our office and only one cartridge tape drive. My problem is that I can't seem to get a remote dump to work over the Ethernet if the filesystem takes up more than one tape. The dump aborts with an error at the end of the first tape and my choices are to abort or restart (neither of which is appropriate). If you have any suggestions of the magic words I should mumble to get this to work, please let me know! BTW, if it makes any difference, we are running Sun Unix 1.4. Thanks in advance for any help you can provide.

It seemed that the disk partition sizes could have something to do with it, at first; though what eventually worked for one Sun did not work for the other. Has anyone else come across such problems? -- ------------- -Jim Crammond JANET: jim@uk.ac.hw.cs ARPA: jim@cs.hw.ac.uk UUCP: ..!ukc!cs.hw.ac.uk!jim ----------------------------- Date: Tue, 6 May 86 13:58:28 mdt From: unmvax!sandia!pjatter@ucbvax.Berkeley.EDU (Paul Attermeier) Subject: Sun color screendumps We are looking for the software required to dump our Sun 3/160 color monitor (Sun-Unix 3.0) to an Imagen 8/300 laser printer. We got some programs from Robert Jacob at NRL, but they don't work with our color monitor (complains about bad header information).
