In response to "touchup" and the printing of its output to a non-postcript
laserjet, we've been successful in saving touchup files via the raster
option and then printing them with "lpr", (/usr/ucb/lpr).

Subject: Re: DB-15 slide latch
Slide latches in general are a marginal technology, but Sun complicated
the problem by using cheap foreign parts to save a few cents. Go to your
local parts supplier and order slide latches from a reputable connector
manufacturer such as AMP. (The local ripoff joint, Cables & Chips, wanted
$3.20 for one; this means the real price should be a buck or so.) The AMP
latch is made of much better steel and has nearly a millimeter more length
in the smaller notch. It holds PVC transciever cable securely and can
even deal with that $&#!@ Teflon cable most of the time. I have the AMP
part number written down somewhere but can't find it right now....

The 1987 Sun User Group tape, available from Sun User Group c/o Sun for
$100, contains a program that converts Macintosh LaserWriter fonts to Sun
vfonts. There are lots of fonts available for the Mac.
The program is in the directory 'sunview/suntroff/LaserWriterFonts'. I
routinely use Helvetica 18 for my SunView pop-up menus - looks nice!
The tape also includes 176 fonts ranging in size from 10 to 24 points.
These are in the directory 'sunview/suntroff/LaserWriterFonts/VFont'.
Since these are, for the most part, proportional fonts, they're not of too
much use for screen applications. The Helvetica is nice, however, for
menus.

Subject: print selection .. an easier way
Reference: v6n136
The following was proposed as a way to print the current selection:
#!/bin/csh -f -e
# print current text selection
echo "" | cat /tmp/winselection - | sed 1d | lpr -h
The preferred method, according to Sun, is to use their utility called
get_selection(1). The man page recommends the following entry in the root
menu:
"Print It" csh -c "get_selection 1 | lpr"
Counting on Sun always using /tmp/winselection is probably a mistake (note
the radical changes in the file system structure that came about in Sun OS
4.0). Besides, get_selection has some nice features (can get secondary
and shelf selections; has built-in timeout and debuging features). Look
it up!
If you think about it, there are a number of useful commands you can build
into your SunView menus using 'get_selection'. Pipe the output through
spell and you have an instant spell-checker! (caveat: I haven't tried
this).

Perhaps you're referring to DataViews from V.I. Corporation, Amherst MA.
DataViews is a (sort-of) object-oriented package consisting of a drawing
tool (DVdraw) and a library of subroutines (DVtools) for developing
interactive graphic programs. Their main customers are people who want to
interface to process control systems (run your nuclear reactor from your
Sun's console!, etc.). The package is nice for developing interactive
demonstrations too. You can associate drawing characteristics, e.g.
color, with live or canned data. The package also has a nice selection of
'graph formatters' which let you put bar-charts, dials, knobs, meters,
clocks, etc. on the screen, and tie these to variables.
The package is useful for some types of prototyping, but is really not a
generalized prototyping package. For that you may want to go to something
like Virtual Prototypes Inc's (Montreal, Canada) VAPS product, if you've
got the bucks.

Virtual Prototypes, etc ...)

The command arp -a lists the entries in the Internet-to-Ethernet address
translation tables. Unfortunately, these entries are volatile. One trick
may be to rlogin to your computer. This seems to put an arp entry in the
table, so arp -a should report the information you want.
This is a klunky way I admit... perhaps some arp expert will show us the
'right' way to do this.

Subject: FR device drivers
Does anyone have a freely redistributatble device driver for sync ports?
Our problem is that we need to read something almost but not quite
standard and we don't have a source liscence.
On a seperate but related note, does anyone have a standard tty device
driver they can share?

Subject: need SNA Peer-to-Peer info
I'm looking for info on Sun's SNA Peer-to-Peer product. Has anyone out
there used it? Is it robust? Did good, hard use of it bog down your Sun 3?
How was the support? Is there another 3rd party product for this protocol
that you liked better?
Email replies to me, please, and I'll summarize to sun-spots if there is
enough interest. All war stories accepted.

Subject: Multiple Swapping: three partitions?
I as most of know that one can swap on 2 drives(e.g.: sd0b & sd1b). This
is great and really will in some cases enhance the performance of your
machine(s). I won't go into the details here of how to do this since it's
already been discussed here before.
My question: Is it possible to swap on THREE partitions? I wonder this
since I have several machines with 2 swaps(xy0b & xy1b), and I now have an
Interphase 4200 w/a CDC9772-858mb drive. This drive is faster than all get
out. I would like to also swap on it. A usual configuration line in your
kernel for 2 drives looks like this:
root on xy0a swap on xy0b and xy1b
fstab:
/dev/xy1b /swap swap rw 0 0
So why couldn't I do this??
root on xy0a swap on xy0b and xy1b and ip0b
fstab:
/dev/xy1b /swap swap rw 0 0
/dev/ip0b /swap2 swap rw 0 0
Seems like this should work. Anyone have any experience with this
configuration? Anyone have any concerns that they'd like to voice
regarding this??

Subject: Speech on a Sun?
A recent question entitled, "Sound on a Sun" prompts me to ask a similar
question: does anybody know sw/hw for digitizing and playing back speech
on a Sun? The application involves generating audio messages from a set
of pre-recorded phrases. I know half an answer already: there is an OEM
voice board available from MicroVoice in Calif. for VME bus that looks like
it would do nicely, but they have no software for it.
Please respond to fkuhl%amadeus at gateway.mitre.org.

Subject: NeWS Question
I've just received NeWS 1.1 for my Sun 3/60. Right now I'm wading through
the documentation that I recieved with the software. However, before I've
even started, I have a question that I cannot find an answer for in the
documentation:
If I write a NeWS-based application, can I run the application on another
Sun that does NOT have NeWS loaded on it? If not, how much of the ~16
Megs of NeWS software must be loaded on the workstation?
NeWS looks like interesting stuff to develop applications in, but my
workstations do not have 16 Megs free just to support a couple of *neat*
application programs.
Thanx for the help...

Subject: Question on Unused Client
Recently, my group here at Kodak purchased a 3/260 and a 3/50. The 260 is
the server and the 50 is a diskless client. When we initially installed
the 260, we actually specified 2 clients in the setup program just in case
we ever got another workstation. I don't know if that will ever be the
case. My question is this: does this unused client take up any
substantial amount of disk space on the server? I only have a single 280
Meg disk and I'll take all the extra free space I can get.
If the information I seek is somewhere in a manual, could some please let
me know where? I've looked and all I can find is info on adding a client.
I found nothing about removing one.
Thanks for any help.

Subject: Macpaint to raster converter (source)
After seeing two requests for a macpaint to raster converter, here is my
contribution. I wrote this program a year and a half ago and haven't used
it much since, but I just recompiled and it does work. It was designed to
display Macintosh screen dump images, but can be modified for larger
images by changing NROWS and NCOLS. This version was written before there
was a Mac II, hence it does not support color. It should be compiled with
the -lpixrect flag.
