Re: Pink Screen

I'm looking to speed up my SE/30. I have been burned by a color video card
that does not support OS 7.5.5, so I'm looking for input on good options.

Did Daystar make a CPU socket 50MHz '030 accelerator with FPU?

Could I expect a MicroMac DiiMo '030 with pass thru PDS and a RasterOps 264
video board to live in there comfortably? Space and compatibility are
concerns. (I have reason to believe that the RO video board WILL support
7.5.5)

Any compatibility problems with '040 PDS boards? (Provided I could find a
dual PDS adaptor)

And finally, the Doozie: Does anyone know if any company ever made a PPC PDS
board for an SE/30? (Hey, why not ask?)

Thanks,
Brian

I have come into possession of two Mac Pluses that work was going to put
in the Dumpster. I hope to get at least one operational and use it as
web text machine. I know zero about Macs (well, only a little) and have
never been inside one or any machine. Here's what I've got, what do I
need:

One of the Macs is 4 Megs (says indelible maker on back). The other
??. Have one power cord, one keyboard, one mouse with one serial pin
missing. No disks with it, though a friend sent me "images" of
6.0.5.

The four meg Mac turns ? into happy face when I insert installer disk.
Churns, then does nothing. Happy face in middle of otherwise dark
screen. Disks do not eject. Paper clip works badly ... on both. Pushing
clip will raise housing; tweezer will then grab disk and pull partially
forward. With third hand, grab disk, pull about half inch out, second
push on paper clip then ejects disk.

The other Mac probably has bad power supply (guess). Get half inch
strip of light, top to bottom on screen. Can barely make out ? and can
barely see that disk insertion turn it into happy face, too. Also
churns, does nothing; same disk ejection problem.

OK, where do I start, after I get the 10-inch TORX wrench needed to
break open the case? Or do I have bad set of disks? There are 5, named
Network Installer, System Tools, Utilities I, Utilities 2 and Printing
Tools.

Have no manual (yet). Have been told that if I can find cables any
modem (up to 9600 baud) will work and most any hard drive, if
reformatted for Mac.

Advice and suggestions would be appreciated.

I have an LC that has worked perfectly for many years that is until the
mouse button failed.. it made a flat click and stayed jammed in the down
position, I a have tried gently tapping the mouse on the side but it refuses
to budge back to its non depressed position, so my question is how do i take
it too bits and replace the spring mechanism?
regards rwater

You can't fix this, save for replacing the small micro switch. The small
switch inside the mouse is broken. More specifically, the tiny bimetal
spring inside the tiny switch is broken. This is a "Classic" problem with
this series of mice. Try Sun Remarketing. I ordered a few of these
switches a few years ago, and fixed this myself.

Dale,

No idea as to the cause, but this is a topic that has been posted on Apple's
discussion board. One other person has mentioned this problem with his
Performa 5200CD. You might try the URL

http://discuss.info.apple.com/boards/display.nsf

for the discussions related to video displays, and this individual's inquiry
in particular.

One of the buildings in our district has a neat Power Mac 5200/100 Performa.
I love it and use it all the time to scan in pictures on an attached
OneScanner. They also have Adobe Photo Shop on board. The default screen
color has turned to a pinkish/purple and does not change. All white areas are
pinkish/purple and sometime flickers to either a deeper purple or or more
pinkish pink. Resetting the color tints simply changes to a different color be
the default pinkish/purple remains the same. My guess is that some type of
circuit filter or something has failed. A check with our homepage shows the
Gif Images made with the Mac at www.tanet.net/~sunlib, are fine. Any ideas
with this?

The ROMs in Macs are not usally soldered. The Plus has socketed ROMs
which can be swapped with a 128 or 512 as an upgrade, this is what may
have happened to your machine. They have to be put back in as a pair and
in their correct sockets or your Mac wont work. If you can get a hold of
another Mac Plus board then you may be able to compare them. The ROMs
are the 0.3"x1.2" chips which have (C) Apple and a date on them and may
be marked with a 'H' and an 'L'.

What is advantage of upgrading the ROMs in a Plus? What is the most recent
version of the ROMs? Is there a way to check the version I have without
cracking open the case and looking?

Thanks,

I recently recieved an offer for an encyclopeadia on CD-ROM. For the system
requirements it listed a Mac IIci minimum.

Is there any reason that this program would not run on a SE/30.

From all i can tell the only differences are processor speed and the color
factor (which can be over come witha card).

Is there something else I have over looked?
Any info would be greatly appreciated.
TIA

In response to:

Trouble? We never had a day's trouble in four years it was in daily use. It
still works. The head would get hot if you did a dense black over a large
area. We later got another ImageWriter II, a LaserWriter and then another
then a ColorStyleWriter Pro but all that is another story.

I've got one better for you. In addition to the other Imagewriter I's and
II's I've purchased used over the past year or so (at bargain prices at
such outlets as Goodwill, etc.....), my ORIGINAL Imagewriter I that I
purchased in 1984 for use with my Apple //c is STILL GOING strong today in
1997--attached to my Performa. And I haven't even had the print head
replaced. What a machine!!!

I just got a PowerBook 100 for a song. I'm sure the main battery is
completely dead, because it will only start up with the AC adapter plugged
in. Whenever I do start it up, it says "Battery Reserve Power completely
gone - will sleep in 10 seconds to preserve memory." which it then does. My
first thought was to replace the backup memory (the 3 lithium batteries)
but that doesn't help. I've searched the Tech Info Library and back digests
of the Classic Mac mailing list, but I can't find any mention of this
problem.

TIA for any help,
Fuzzy

P.S. Does anyone know what the switch on the back of the PB that shows the
battery connected (to the AC power?) and unconnected is for?

I have just bought an old SE/30. I have heard rumor that it can support an
external monitor. What size of monitor, color, grey scale or B/W will it support?
Does anyone know of a source for the the video card? Word processing is not
fun on the 9" screen! I would like a larger monitor if its not to
expensive.

It will support a variety of monitors, depending on the card you can find.

Try < http://WWW.MICROMAC.COM/products/accelerators.html> for accelerators and
Sun Remarketing <http://www.sunrem.com/> for video cards.

You can go colour, grey scale and the neat thing is that the two monitors
will give you a side by side view. So you can have your dictionary open
on one screen and the document on another. I've heard of people using 20"
grey scale monitors on SE/30s.

Go for it!

...enough to prevent premature failure because of heat build up. Another fan was
a vibrator placed inside the Mac and the ossicollation of the little blade
created some air movement and hence cooling.

Terrific! Just what you're sensitive, heat-stressed electronic components
and solder joints need: *vibration*!....

Actually the *vibrator* was a piezoelectric device that was almost imperceptable to
the operator, but created a very gentle (perhaps too gentle) air circulation. I suspect
the vibration associated with the floppy drive was probably greater. The Kensington
System Saver (top-mounted fan with convenience outlets) was probably the most
popular of these cooling devices. My Plus has operated without missing a beat for
almost 11 years with one of these jewels.

need a newer machine....

Not true. I'm using a MultiTech MT1432MT modem at 14,400 baud with System
6.0.8 on a PowerBook 100 without problems.

3. If I looked for a used inkjet or laser printer, to run on my system as
it is now, what should I look for and how much might it cost?

Small Dog Electronics has a Stylewriter 1200 available for US$109. E-mail to
<Kibbles&Bytes@smalldoggy.com>. Not being familiar with Stylewriters, however, I
don't know whether or not this one requires System 7.

There are also many non-Apple 24-pin dot matrix printers that you might consider,
using GDT Softworks printer drivers and/or serial-to-parallel cables, and System 6.
These give remarkably good output, particularly with fonts optimized for dot matrix
use. I've used an Okidata 393 with GDT's PowerPrint software and was
pleased with it.

No real ideas, but a bit of info that might be useful: a friend of mine
has a Power Macintosh 8100/80 (internal video) that did the same thing
feeding a Portrait Display Labs Color Pivot monitor. Some days were worse
than others, and it was only the screen that was a problem, nothing else.
Please let me know if you find out more ... or if you need someone to
help you test a hypothesis! TIA.
