Subject: 4MB SIMMs installation problems -- LC/cx: works; IIx: doesn't work
Reply-To: steff@ims.uni-stuttgart.de
Organization: IMS, University of Stuttgart, Germany
Date: Wed, 7 Oct 1992 17:13:35 GMT



G'day,
	we are trying to equip a couple of Mac IIx's with more than
8MB memory, using 4MB SIMMs. Our local distributor offered SAMSUNG
SIMMs with the (according to the delivery notice) following model #:

SAMSUNG KMM584000A-7 9222 SEC. 

the writing on the chips themselves says:

        KOREA
        218Y
  KM41C4000AJ-7

ok, so we tried to install the SIMMs in one of the IIx's, and only got
system errors (the flat accord sound) at startup.

 We installed 4 4MB SIMMs at a time in bank A -- no success, also
tried 4 1MB SIMMs in bank A and 4 4MB SIMMs in bank B, in the latter
case _sometimes_ the 4x1 MB in bank A would be recognized and would
pass the memory test, but nothing in bank B (i.e. the Finder would
report 4 MB total memory available).

Our initial suspicion, that the chips might be bad, was dismissed,
after a test installation in both a Mac LC and in a Mac IIcx was
successful.

My question now:
Is there something special about the Mac IIx compared with the cx and
the LC that would make the chips work in the latter two but not in the
former? Did we do anything fundamentally wrong when installing the
chips? 

Apologies, if this is a FAQ ( in this case, a pointer to a c.s.m.h FAQ
file would also be nice )

Any helpful advice is highly appreciated. Thank you.

1/8" allen wrench works great too.  Easy to find in long t-handle styles

Subject: TI microLaser printer - feed mechanism bug, and a fix
Organization: Cornell Theory Center
Date: Tue, 13 Oct 1992 21:14:29 GMT

A recent issue of MacWorld or MacUser (forget which) had a brief reference to
a problem that has been showing up in some of the Texas Instruments microLaser
printers.  Since I am thinking about purchasing a microLaser Turbo, I called
TI to get their side of the story.
 
They claim that _some_ of the microLasers develop a problem in the paper feed
mechanism that causes a jitter, or stutter, in the feed rate.  The result is
an irregularity in the printed image about 35mm from the end of the page.
There is a service bulletin out on this problem, and a fix kit is available.
The fix is apparently a couple of spring parts to increase the pressure on the
paper at a particular point in the feed path.  If you have a microLaser that
shows this problem, you can contact TI and request the "35mm jitter fix."
The phone number is 800-TI-TEXAS.
 
If any of you microLaser owners have any other advice or comments to share
about these machines, I would appreciate such info.  Right now, I am trying
to decide between the Apple PLW NTR and the microLaser Turbo.  The magazine
tests all report that the TI printer is about twice as fast, but some folks
have advised me that Apple's machine is built better, is a lot quieter, and
produces slightly cleaner images.  My best prices for the two printers are
just about the same.

Hi,

Can you people out there using Epson dot matrix printers with your Macs
tell me what sort of software you have to drive them.  I am using a Mac
Plus and an Epson LQ510.  Until recently, I was using the drivers that
Epson supplied in their LQ Printer Software, but it doesn't work with
System 7 and Epson is no longer supporting it.  :(
 
Are there any shareware drivers that are any good? 

Are the commercial packages available actually worth the cost?

Earlier in the day I installed a Quantum 240 MB LPS drive into my SE/30 and 
that went off without a hitch. But after I powered it up I noticed that the 
video was a little off...make that a LOT off. :-(  Internal video is the 
standard 9 inch monitor displaying 256 grays via a Micron Xceed Color 30 
Video Card and Xceed Gray-Scale 30 Video Adapter. The video was off in 
that the video image became shifted to the left, i.e. the Apple and File 
menus went off the screen, plus the black border at the top and bottom of 
the screen increased in size to about an inch. However when I reinstalled 
the original Sony drive the video displayed no problems. Could this be the 
result of the LPS drive using less power than the Sony drive and thus 
impacting the Micron video components in some way? If you can explain why 
this is happening and how I can get the LPS drive to work I would greatly 
appreciate it.

Oh my God, now it comes out.  I don't know if any of you remember the Apple
/// but it was a complete disaster on all points concerned.  Our school
had one and the thing never worked right at all, ALWAYS overheating..sound
familiar.

Woz was in all practical purposes one of many talented people at the time,
any of which could have brought us the computer PC revolution.

John Von Neuman was technically considered the father of the ONE cpu machine
we all enjoy on our desks today, but many people around him contributed
to his vision or their own vision of what computing was about that led us
to where we are today.

I personally work with many talented people everyday here at UW-Madison and
any of them I am sure could be a Woz, or another Von Neuman in the parallel
computing field...

I tend to agree that catalytic circumstances put these people in the drivers
seat when technology at a given point in time reaches a point where anyone
could put together a product which provides a useable market that wasn't there
before.

I think it basically comes down to who's first?!  In that case its a crap 
shoot.

Yes.  You need 32-bit addressing to address more than 18 megs of RAM;
that's why Apple implimented 32-bit addressing.  The difference (12 megs,
in your case) show up as system memory under 24-bit addressing, but they
are actually not used for anything.  The other two megs are what the system
actually uses.

I've been using a Stingray for about 8 months. (I got the neato-cool
"Stealth Black" colour). I just put it on my mouse pad that I used to
use for the mouse. Now, the heel of my hand rests on the soft pad.

What's nice about the large buttons is you don't have to go hunting for
them if you are, say, in the middle of staring at a conplex drawing on the
screen and don't want to look away. Of course with use, you'll develop a
feel for the placement of controls on any device.

I have the dirt accumulation problem too. The manual says that it is "self-
cleaning", but that is hogwash. Like another poster, I pop the ball out
daily and clean the well. You may also occassionally have to clean the
rubber rollers. Use a toothpick or something hard but not sharp. Be
careful not to dislodge, tear, or puncture the rollers.

A very nice unit. I'm glad I have it.

   until one side has been completely detached from the motherboard, then
   work on the other side.

Thanks for the info!  I just might try this.  One thing about this
part tho':

I would strongly recommend using solder wick for the removal of the
crystal.  This will be a lot faster and probably safer (won't have to
heat up the board etch nearly as much).  Also, then there won't be any
solder already on the board when you go to put in the socket, so that
procedure will turn into a 30-second affair rather than a number of
minutes.  And again, this will be more gentle on your board.

I've mailed this to a few people in response to their Plus problems.
There seems to be enough related traffic to warrant a post.

First: DON'T pay someone $250.00 for a new power supply. It's much
cheaper (and fairly easy) to fix yourself.

Second: It does NOT require special tools to open a Mac Plus/SE.
Ideally, you need a long shaft Torx driver (similar to a hex key, but
not the same) to get to the screws in the case handle. You can GET BY
with a long, narrow-bladed, flat screwdriver. It will fit into
the slots in the Torx nut. Be careful not to strip it out.

There is a book out by Sam's, called something like "How to Repair
and Upgrade Your Mac". It describes most typical failure modes for
Mac power supplys, describes how to analyze them, and what parts to 
replace/upgrade. It comes with a diskette of test programs for checking
and adjusting the monitor size, alignment, etc., and lists suppliers
for the assorted suspect parts.

I picked up a dead Plus, performed all upgrades recommended in the book
(which also repaired the problem), and now have a working Plus with
an upgraded power supply (including monitor drive components).

Total investment:
Free dead Mac Plus
$60.00 for an upgrade kit from Soft Solutions - includes better flyback,
assorted better capacitors, and a new crt power socket (I bought a power 
transistor also)
Approx $25.00 for the book. (It also covers SEs and Mac 512s)

Not a bad deal.

Hi again,
 
By my previous message I think my computer is almost dead.  Here are my
options, what would you choose: (I have been looking for an opportunity
to upgrade for over 2 years.)
 
1.  Buy a IIci in hopes of upgrading someday to a quad 700.  I am
worried that the ci will not be available next week after the 19th of
October.  I am also wondering about the perform of ci vs. vi (vx).
 
2.  Buy a IIvx (vi) next week.  I don't have any firm rumors of any type
on this computer (I don't even know the name).  Is it upgradable to the
quad series?  Is the performance worth the cost?  
 
3.  Fix the Mac + (appoximately $80-$230) and continue to dream about a
better cpu.
 
4.  Begg, borrow, or steal my brother's Mac+ and trade his ram (1 meg)
with my ram (4 megs).
 
I am not worried about the configurations, I have been building around
my computer with a modem, disk drive, and memory. 
I will buy on the educational discount (does this make a difference
while dicussing the availablity of the IIci next week).
Any action taken will occur after the weekend of the 17.
