Subject: Re: SunView questions on video retrace and color icons
Reference: v6n265
After trying some experiments a while back, I determined that the icon
uses the same color map as the base frame. Here is a simple example which
creates a frame with a 4-color icon:
________________________________
#include <suntool/sunview.h>
#define CMSNAME "test"
#define NCOLORS 4
/* RED GRN BLU VIO */
static unsigned char rmap[NCOLORS] = { 255, 0, 0, 255 };
static unsigned char gmap[NCOLORS] = { 0, 255, 0, 0 };
static unsigned char bmap[NCOLORS] = { 0, 0, 255, 255 };
main()
{
Frame frame;
Pixwin *pw;
struct pixrect *pr;
Icon icon;
/* Create a frame */
frame = window_create(0, FRAME,
WIN_HEIGHT, 300,
WIN_WIDTH, 300,
FRAME_CLOSED, TRUE,
0);
/* Set up a 4-color map for the frame */
pw = (Pixwin *)window_get(frame, WIN_PIXWIN);
pw_setcmsname(pw, CMSNAME);
pw_putcolormap(pw, 0, NCOLORS, rmap, gmap, bmap);
/* Build a simple color pixrect for the icon */
pr = mem_create(64, 64, 8);
pr_rop(pr, 0, 0, 32, 32, PIX_SRC|PIX_COLOR(0), (struct pixrect *)0, 0, 0);
pr_rop(pr, 32, 0, 32, 32, PIX_SRC|PIX_COLOR(1), (struct pixrect *)0, 0, 0);
pr_rop(pr, 0, 32, 32, 32, PIX_SRC|PIX_COLOR(2), (struct pixrect *)0, 0, 0);
pr_rop(pr, 32, 32, 32, 32, PIX_SRC|PIX_COLOR(3), (struct pixrect *)0, 0, 0);
/* Build an icon with the color pixrect, and install it in the frame */
icon = icon_create(ICON_IMAGE, pr, 0);
window_set(frame, FRAME_ICON, icon, 0);
window_main_loop(frame);
exit(0);
}

We found that you can fake out setup(8) on our class B net. For example,
if the tapeless diskful client is really 128.136.10.128, just tell setup
that its host address is 128.136.2688 (2688 = 256*10 + 128). It's worked
from SunOS 3.2 through 3.5

Subject: SCSI disk format?
Can anyone explain, in simple terms, what "alternate cylinders" are? Why
are there two of these, on average? why can't I have none? If my SCSI
disk has N cylinders, the format program restricts me to using N-2 of
these for data. Where do the other two go?
Please MAIL replies, I will summarise (if there is anything worth
summarizing!).

We recently had a problem with a Miniscribe drive that we purchased from
Parity and were told by them that the 3.x formatter has a bug that keeps
it from working correctly with Wren's and Miniscribes.
They recommended that we use the formatter that comes with 4.0. Due to
more severe problems I wasn't able to try it out.
Apparently Parity ships all of its drives pre-formatted, and doesn't
normally say anything about the possible problem.

Subject: Opportunity for SEX at the SUG
Now that I have your attention...
Of course, I am referring to a possible Software EXchange at the Sun
User's Group meeting in Miami, December 4-7. I will be there, and I
assume many other Sun-Spots readers will also.
It occured to me that this is a perfect opportunity to obtain and exchange
software. If everyone brought a tape, with anything they had that was
interesting, you could contribute your stuff, and leave with everyone
else's.
The major hurdle to this problem is finding a machine upon which to store
the incoming stuff, and let people copy off what they want. Perhaps some
vendor could graciously allow the use of a machine. I should point out
that lots of people would be coming to your booth, and that this selfless
act would be viewed as a positive, community-minded thing. In addition,
vendors could make demo copies of their products available, which is
always a good marketing idea.
I am willing to coordinate this project, just to see what happens. I
would like to hear from people who think this is a good or bad idea, as
well as people who are willing to bring stuff, and especially vendors who
could offer part time use of a machine. This could be the start of
something big, or maybe I'm just talking through my hat. Either way, I'd
be interested in people's reactions.
And just to be safe, bring a tape to SUG!

Hi. While this might be an old problem, it is certainly annoying to its
user: SOMETIMES, when I select the "shelltool" entry of the top SunView
menu, all I get is a series of USELESS shell windows, which would say to
any single key stroke "Use 'exit' to leave csh"!!!
Has anybody out in the NetLand seen this? Does anyone have a cure to it?

We are planning to use a video backup for our Sun 3/280 with 15 3/60
clients. Currently we have 1 800 Mbyte disk and plan to add another in a
few months. We perform level 5 dumps each night (between 2-5 Meg). Has
anyone any information regarding suppliers of video backup systems ? Has
anyone any advice (should we use something else?)

Subject: Re: Algebraic Calctool with Trig Functions
I have written a number of programs, including a desk calculator, that
evaluate algebraic expressions. In addition to the standard library of
math functions, the language allows user-defined recursive functions, and
I have files for roots of functions, integration, etc. I haven't written
a program specifically for suntools, but calc can be run in a subwindow if
you like. Best of all, there are programs for performing calculations and
conversions on files, such as output from other programs.

Subject: Bug in Gammontool?
I recently had a strange thing happen to me during a game on gammontool
(BTW, I have a 4/110 with OS 4.0). I had fallen behind in the game and
considered my only hope to avoid a gammon was to leave a piece in the
computer's home board as it was bearing off. Well I was very fortunate,
and the computer left a blot. It was the computer's last piece. I was
again fortunate in that I hit the blot, and filled in all the points on my
home board. After bearing off two of my own pieces, I left a blot in my
own home board figuring I might as well play aggresively since I was down
13 peices to 1. I figured I had nothing to lose. After all, I was
probably going to lose the game, and the computer could no longer gammon
me, right? Wrong. The computer hit my blot. Then on the computer's next
turn, the computer rolled double 6's (Hmmmm.) and not only brought the
last piece all the way around the board and beared it off, but hit me in
the process! The computer announced that I had been backgammoned, (after
all I had a piece on the bar). Is this correct? Can I be backgammoned
even if I have born pieces off?

Subject: SDST110 config file in sun4 distribution doesn't work
The SDST110 configuration file distributed on the sun4 tapes doesn't work.
A lot of functions dealing with the SCSI devices are undefined when you
try to make the kernel. Adding the "sc" controller to the config file
fixes up the problem. Looks like the object files for the "sw" controller
just call functions that are really in the object files for the "sc"
controller which aren't properly included by the config.

Subject: ALM Problems
It is a fact that sun evolved as a leader in the workstation world.
However it looks that serial I/O has been a secondary issue[].
Has anybody noticed/solved the problems regarding system halting due to
extensive use of the ALMs? The system being used is a sun3/280 running
4.0 with 2 ALMs. 6 different unix machines are continuously "uucp'ing"
files via modem at 2400 baud on ttyh[1..6].
We are currently at the 3rd ALM patch (5 Oct 1988) and still having
problems... The final say from Sun Tech was that this is a
cabling/hardware problem.. (someone else's fault)...

We have several phtographic output devices from the Matrix corporation. I

Subject: floppies in shoeboxes?
We need some way to read and write MS-DOS 5-1/4" floppy disks on our Sun
network. I know that Sun markets an add-in PC board with an optional
floppy disk subsystem. Are there any cheaper alternatives, especially
ones that take advantage of those nice built-in SCSI ports on our 3/50s?
For example, has anyone out their successfully gotten one or more floppy
drives and their controller to work in a Sun shoebox?
I would be happy to send a summary of any responses to sun-spots.
Thanks.
