Yes there is.  Mac II and IIx's need the 4 meg simms with a PAL chip.

 You also need Mode 32 for the system to recognize the additional memory.

Yes, it's relatively easy to do. However, screen shrinkage is a symptom of
worse problems internally. Macs -do not- just shrink the video when
everything else is working OK. You can adjust the video now, but the video
will fail entirely if it isn't tended to. If you wait too long, it can fuse
the connector to the CRT, and you will have to replace that too! IMHO, you
should either get the analog board replaced ASAP (Cost about $250), or
better yet, if you can afford to do so, just buy a replacement system.
Personally, I wouldn't spend much fixing a Mac Plus. It's resale value is
dropping like a rock.

If you want to adjust the video, you will need to open the case. You can't
do that without special tools, but there are kits available in the
mail-order catalogs and the back of Mac magazines for that. You will also
need one of those plastic "TV Adjustment Tool Sets" that you can get at
Radio Shack, with the funny little plastic screwdrivers. WARNING - This
adjustment required working on the machine with the case off and the power
ON. There is a distinct hazzard of electrical shock if you are not VERY
careful!

Once you take the Macs case apart, look on the left side. There are four
adjustment points, which should be clearly labeled with pictures on the
paper that protects the left side of the circut board. Plug the Mac in and
turn it on. -Carefully- use the plastic tools to tweak the adjustments,
working from the left side. If they are stiff, try adjusting them from the
other side. You should only adjust the ones for height, width and
brightness. DO NOT attempt to adjust the one marked with a straight line
over a dashed line! That is your voltage levels, and if they get out of
spec, the system will refuse to work at all.

Good luck,

I can't let this go without adding my 5c worth. I actually met 
the Woz some years back, when he was visiting the UK's major
Mac show. (He's not too tall, is he?)

Anyway, having used Apple since the original Apple ][, I was 
kinda overcome at bumping into someone I'd always assumed was
a marketing invention designed to promote the American Dream
(see above)... so I knew I just had to get some objective proof
that he really existed.

An autograph would've been fine, but do /you/ take an autograph book
to a computer show? And I don't even own an autograph book...


But I do have an autographed copy of an apple price list.

How does the basic Apple warranty work? I believe that it's a one year
warranty. I've been told that in order to get it you have to have purchased
from an "authorized Apple Dealer". Is this true? What about mail-order dealers?
I've called several and they say they are not authorized. Avoid?

I posted an equivalent question a while back but then my company moved and
our computers and network were down for a while so if anyone responded, I

"EtherPrint Plus" connects up to 4 localtalk printers to an ethernet.  They
show up in the chooser just as if they were directly connected via localtalk.

One problem:  security!  We have a multizone campus network, and apparently,
no way to allow password protection for our localtalk printers using our
EtherPrint Plus box.

Most mail-order places (MacWarehouse, MacConnection) seem to stock it.

No it didn't. (Gee, I feel like I'm in a vice-presidential debate.)
It was the previous poster who drew that distinction by first saying
that Woz "once" was "one of the best engineers of all time", then saying
that in his opinion he "still is". So by *that* person's definition, it's
possible to enjoy that status, then fall out of it. I was merely inquiring
as to what basis he was using to make the judgment that he "still is".
I also note that we've never seen a follow-up answer about it.

Now, I really don't think this is worth expending more bandwidth on,
so if there are other points to be made I welcome you to do it by email.

   Both Mac World and Mac User have had good reviews on modems in the

is very reliable (even under poor telephone lines) and is fairly

Yeah.  My roommate just bought a system very similar to that for about
the same cash (to play games :-)).  It seemed _Really_ slow so we tried
poking around the configuration files, but got nowhere.  Then we
found a guy at work to set it up, which took a whole evening and a
couple buckets of chicken blood for a PC-config ritual.  Seems
that the standard configuration for Back Of The Truck Computers, Inc.
gave this 486/33 about 286/12 performance.  Now that the performance
is up to par, a couple keys on his keyboard are giving out, on a
twenty day old computer!  Sigh.

Now I remember why I bought a Mac.
