I think that he (the author Travis was referring to) meant a voltage DROP. 
With V=I*R, if the voltage drop is 0, then the current (I) must be zero. I
think that the previous guy meant a larger voltage DROP and hence a greater
current. I am sure Travis just misunderstood the statement.

Yes. thank you very much. I did in fact find it useful. I like to learn stuff
like this. I appreciate all the articles by people in regards to this IIsi
upgrade, because I have seen a lot of stuff come in to the net as a result
which I have learned much about my machine from. I appreciate it when you
EE dudes (or dudettes as the case may be...) write in with stuff like this.

Hi All,

	Please reply direct to me - I will a) send a summary of my responses to
anyone who asks, or b) if I get more than 5 summary requests, I will post the
summary to comp.sys.mac.hardware - Thanks!

	I have a Mac Classic (not a Classic II), 4/40, System 7.0.1, with a PLP
LS and though a switchbox a modem and a CasioLink cable. Std (small) kybd &
mouse.

	Ocassionally (20% of the time?), when I turn it ON, I get no-change 
screen (ie, still black), and a faint "tick" sound.  A LOT like the old
crowbarring sound we used to get when we upped the power in the old Mac Plusses
too high, just much quieter.  Of Course, the unit is immediately shut off, and
if unplugged from the wall for 5-10 seconds, and tried again, it always works.
Also, this has happened in the middle of the session (ie, screen goes black,
ticking heard), but much less often (maybe 3 times so far).

	The unit is about 18 mos old.  We moved (w/ the unit in its original
box, by hand, in my car), and it didn't start happening until after the move,
but not even then did it start right away.

	The unit has always been on a surge/spike protector, and as of
yesterday, has been on a UPS system ( it still went black this AM, though).

	I get the feeling that perhaps the power of our heat pump cycle on or
off (sag or surge) might be responsible, maybe (through a TrippLite UPS?)?  
Humidity? Dust / CatHair (it is fairly clean inside, I just checked).

	I would like to maybe _lower_ the internal power a little bit, but
when I opened it up, all of the pots on the PS board are unlabeled (except for
things like P17, P13....  Can anyone enlighten me as to which ones are what,
and since I no longer have access to a _digitial_ voltmeter, give the rotation
for increase / decrease power on the appriopriate one (I'm gonna have to
eyeball it). Unless of course there is a good tech book about the Classic (I
have the one about the Pluses / SE by Larry Pina -no use here)...  Sigh, I wish
the guts of the Classic were labeled like the Plus - real easy to work with!
But, I did notice (after putting it back together), that the old "battery
compartment cover" actually covers access holes to the pots - so I won't have
to take the cover off to do the adjustment?

	Oh Well, Thank you for your time & replies.

	Please, again, reply directly to me and I will summarize!

	James

choose millions of colors I get a strange ghost-like after image of the open

Hello,

I am setting up a AppleShare file server. The Server will
be placed on the EtherNet side of my localtalk/EtherTalk
network.

I will use 17 MB of M in the SI and 20 MN RAM in the SE/30
I will use a Maxtor LXT340s drive in either machine.

On the SI I will use a TechWorks ethernet card with the SONICS
chip set (should do buss mastering on the SI).

I would use a Asante card for the SE/30 on the SE/30.

Applecation other than Appleshare would be for a 4D-Server,
network Fax, etc.

Anyone know which would be faster for Appleshare?

Actually, the way the two busses work is that each is electrically
seperate, but at no time can there be more than 7 SCSI devices attached
even with the 2 busses.

The chip is capable of lots of neat stuff, but the SCSI Manager doesn't
support any of them. To do this, vendors must hack the SM.

When you first boot-up your Mac with no open windows, Pull down the menu
under the apple and select "about the finder". Notice all the white space
after the finder and only a small amount after the system. For maximum

  You got me, that's the real reason I haven't bought a Macintosh. I'm

  I don't agree. No computer is powerful enough. After assisting people
  with using their computers and watching them upgrade, and just by
  using faster computers myself - I have figured out that a person's
  efficiency is directly proportional to the speed of the computer
  they're working on. So hey, if I can wait a quarter or two and maybe,
  just maybe [probably for sure] get a computer that will be a great
  deal faster for the same price - then I'll do it. And I'll just work
  on the University's fast computers until then :)

This one is easy, just open the "About the Finder" menu item in the Apple
Menu. The machine will tell you how much memory it thinks it has.

To your question on the Macintosh SE's memory configuration:
				I own a Mac SE myself and upgraded it to 4 megs, but not 2.5. According to
Larry Pina's "Macintosh Repair and Upgrade Secrets" book, the SE has two rows
of SIMM slots. If you hold the logic board with the ports at the top, and the
SIMM slots at the bottom, row 1 is the two SIMM slots closest to the top, and
row 2 are the closest to the bottom. You *have* to put the one megabyte SIMMS
into row 1, and the 256K SIMMS into row 2. There are *two* resistors that have
to be removed to get the full 2.5 megs working correctly. R35 and R36. R35 is
the resistor with "256Kbit" written next to it, and R36 is the resistor with
"one row (only)" written next to it. make sure they both are not there (R36
should not be there in the first place...). After cutting the R35 resistor,
make sure it does not touch anything, in fact, cut it out, you won't be 
wanting it again later.
				Make sure that the SIMMS sit properly in the slots. As for the Carmen
Sandiego game, make sure that it doesn't require a certain system version, or
Macintosh Type to run. The memory setting in the get info window is the 
partition that the program will take when run in multifinder... My last 
recommendation is to disengage *ALL* of your INITs/extensions/controlpanels
etc. Many times these will intereact badly with games.
				Lastly, the SE never hgas or will be able to support virtual by itself.
You need at least a 68030 processor in order to use it. I would tend to think
that the memory still wasn't in right, or that the game won't work with your
SE.  Good luck.

According to the DTS Q&A stack:

  The only Macintosh models that currently combine the two stereo channels 
  into one for playback out of the internal speaker are the Macintosh SE/30 
  and the IIsi. All others use just the left channel. If you would like to 
  check for the machines ability to do mixing, you can use Gestalt. This is 
  documented in Inside Macintosh Volume VI, page 22-70.

No doubt new machines were released since this was written; I don't know 
what the situation is relative to the Quadras and Powerbooks.
