I plan on using a Mac in a high school classroom.  It would be nice
to be able to project to output to a device that can be used as
a dynamic transparency.  I have seen this kind of device for old
IBM CGA output.

Any pointers will be appreciated.

They're not hard to open - you can find the torx wrench at most hardware
stores.  However, the 100 is also relatively easy to damange unless you
are very careful to remove the batteries before you pull it apart.  I know
of at least 2 units that had their fuses blow because of this.  So, if you
want to take it apart, make sure that you remove both the battery pack and
the batteries in the back.

There can be another surprising source of problems: the keyboard. We had a

Well, it depends on what you want to do with it.  If you don't need color now
or later on, then don't do the upgrade se to se/30.  With $750 you can easily
get a 33mHz 030/882 accelerator w/o the video option, and it will run about
2x faster than the se/30.  Or you can get a 25mHz 030/882 accel. with video
option for about the same price (compatible with most fpd or tpd in the market)
and still running faster than the se/30 (actually if you look at specs review
in the macuser/macworld back issues, it will run faster than a iici with cache)
If you want the option of color, get a iisi/lc if you can get edu. discount,
but wait until apple introduces new machine (another price drop, I hope).  THe
se/30 is nice, but but you still need to get a color card for color.  Someone
argues that iisi is slow, but if you put in a color card (about the same
price as those for se/30), you should get a faster machine for comparable price

Just my 2cents.

But a mac *serial* cable (what the original poster asked about) isn't the
same as either a "Super VHS" cable or a Mac ADB cable.

BTW, the proper term is "S-video" cable, *not* "Super VHS" cable.
S-video, which refers to a standard for transmitting a video
signal with seperate brightness and color information, has nothing to do
with VHS or SVHS.  Laserdisc players, 8mm camcorders, etc. all have
S-video inputs and/or outputs (and I think 8mm even predated SVHS).

Of course, so many TV manufacturers and SVHS VCR manufacturers are
propogating the term "Super VHS cable" that it'll catch on, just like the
"fact" that Bill Clinton raised taxes 127 times :-)  A lot of the TV
manufacturers would even have you believe that you *need* an "SVHS ready"
TV to use an SVHS VCR.  That's about as accurate as saying that you need
"digital speakers" to listen to a CD player.

If you want to followup to my video, audio, or politically-oriented
comments, please do so in the appropriate newsgroup.

I have the same problem with my IIsi. I had the connections on the hardware
checked and it still blips out. I have heard that other si owners have this
problem. Now I know it exists on the LC, too.

Temporary remedy: Go to Sound control panel and select volume level 7.
This will get the sound back. Unfortunately, some games (ie Falcon) wont
let you access this panel during play. Also, if one program is using the
sound manager and you do this, the whole thing might freeze (this from
personal experience - I don`t know the precise cause).

I, too, would like an answer to this annoying problem. Game players are
not the only ones to suffer - I work with music and it can be really annoying
there, too.

That is correct. I'm not sure about the Plus, but the SE requires you to clip
a resistor or reset a jumper if moving up from 1MB to 2.5 or 4 MB. As two MB
are showing up, there is a possibility that the SIMMs were not properly seated

Larry Pina's Mac Repair & Upgrade Secrets or most memory companies' literature

You are about the fourth person claiming that the SE/30 should be faster
than a IIsi, and not telling us why.

My experience and Speedometer tells me that IIsi is *significantly faster*
than SE/30, except when the active application is loaded in VRAM (which is
easily avoided by setting the disk cache high).

The SE/30 is a good Mac, but for some reason people overrate it a lot on
the net, claiming that it should be faster than IIsi or more than twice
as fast as a Classic II. Both these claims are false.

It depends upon the vintage of the SE. If you have an early SE, you have to
cut a resistor. If you have a later SE, you have to reset a jumper.

I'll check my copy of Mac Repair & Upgrade Secrets and post a follow-up.

The PB100 uses 16-bit wide memory and the 140/170 use 32-bit wide memory.
A memory module can be designed to work in any PB or it can be designed
to only work in one or the other. I believe most modules are designed to

It wasn't the termination because I try to connect the MO without terminating

O.K.- Here's the deal:

Recently, our Plus here in the lab went bad. Upon flipping the power  
switch, I got the trademark 'flup..flup..flup' sound of an overvoltage  
situation. I had Pina's book at home, so I figured I'd try to fix the  
thing myself. The first thing I did was check the analog-to-logic board  
connection, along with the solder joints. Everything seemed O.K.. Next, I  
swapped the logic board of the bad Plus with my own at home. the logic  
board worked fine, so I assumed the problem to be in the analog board. I  
checked R56, the voltage adjustment pot. Nothing. I then replaced the  
capacitors C3, C24, C25, C26, C29, C30, and C31. Nothing. Then I took out  
and tested CR1, CR5, CR20, and CR21. All of these tested fine. I tested  
Q8, the 'crowbar' SCR, and it was O.K.. Still, 'flup..flup..flup...' So,  
in a fit of desperation, I replaced U1, the LM 324N op-amp.  
'Flup..flup..flup...' What in Hell do I do now? Did I overlook something
