 what size vram simm is this?
Nntp-Posting-Host: aix02.ecs.rpi.edu
Lines: 20

Hi everyone. I recently posted about how I received a bad vram chip for my
new LCIII, and someone responded that it may not actually be bad, but it may
be a 512K LC vram chip, and thus doesn't work properly with my computer. So
I'm wondering if anyone can interpret these codes for me, so I can figure
out what type of chip MacConnection sent me.

Each chip says: M518121A-80J
		 2515251

On the back of the card, it says 0593

I believe from the numbers that means it is an 80ns chip, but I can't figure
out what the size is supposed to be. If anyone can help, I'd be grateful.
Please email me your response. Thanks a lot!

If you use System 7, you can use my application Zing which has
a 30 kB footprint 

It is also compatible with the chat program "FishBomb" which allows
sounds and pictures as well.

Both are, as far as I know, freeware 
and should be available on the normal services

Not Quite the point to be considdered here!
Fact: If/When Apple release system 7  then you will see shortly afterwards Apple no longer producing 
Hardware...Look at Next with their NextStep486 to see what happens.
Who is going to pay Apples Prices when they can get the same thing cheaper

No the continued develeopment is because there is becomming less and less 
profit in Hardware, So the Next Step , is 
to make the money in software , after all you can sell multiple pieces of software to ONE 
hardware platform.

As you also said Windows is a nightmare for programmers, so will the 
temptation to sell system 7 to a couple of MILLION dos users be too much 
for Apple! .

 Monitor for LCIII

Hi folks

I'm planning to buy a LCIII but need advice on choosing a monitor.
What do people recommend for a decent 14"/15" monitor?  

I'v looked at some ads and the spec for NEC 4FG/4FGe and the price is 
within my budget, but could LCIII be able to use the various resolutions 
available on 4FG ? Does LCIII only 
support one resolution?

Also any recommendations for a reliable mail order place for LCIII or
monitors? Does anyone have experience with the following mail-order places?

	SYEX EXPRESS 	
	USA FLEX 	

Thanks,

The original Mac II had an Apple MMU chip installed which performs a subset
of the 68851's functions.  If you look underneath your front left floppy
bay you will find three chips, all approximately the same size.  One will
be the 68020, the next the 68881, and the third, approximately the same
size, will be the Apple chip.  It is easy to spot because it has a 'hump'
in the middle of it.


Example:


                         -----------
                        /           \

         |                                         |

That and the Apple logo should make it easy to find.

Could someone please tell me what a 

LaserWriter IINTX upgrade kit is.

Its a small box, which has a bag inn it , seemingly
containing 6 chips  and a IINTX manual.
The installation instructions are most informative and say, in full,
"This product must be installed by an Apple ........."

SO what does this do ? At first I thought it might be a NT to NTX
upgrade, but I thought that required an entirely new board.

Any info appreciated.

The problem is that the pins in the ADB connector 
are close to each other, and if you happen to bend the
cable a little while inserting it, you short the ADB
port. If you take it to an Apple Repair Centre, that
means a new motherboard 

Same goes for serial ports

Powerbook 140-180 Batteries

It is very possible to connect another internal hard disk in any
macintosh if you can find the space to put it. I have a IIsi that came
with a Quantum 80 meg drive. When I ran into space problems, I slapped in
another 40 meg quantum that I had sitting on a shelf. Here is what I did.
 
First off, I was concerned about space. Since both drives are Quantum
quarter height drives, I finally decided that the logical place for them
was stacked one upon the other. Fine, they fit snugly. (I have not had a
problem with heat yet, and these drives have been running together for
over two months.

The next problem was connecting the drive. If you have a spare internal
hard disk power cable as I did, then half of your troubles are over. just
splice in the extra cable so that you get one square motherboard
connector and two hard disk power connectors. If you don't have a spare
cable, you will have to buy the wires and connectors which can be found
in any good electronics store for about $10. I would suggest properly
soldering/heatshrinking the connections to reduce the possibility of
shorts or bad connections.

Next, you need a ribbon cable connection. Again, I had a spare hard disk
ribbon cable, and I wanted to be careful in case this didn't word so what
I did was purchase a crimp on 50 pin cable connector that gave me another
male connector in the middle of my spare cable. The part cost $10 again,
and is easily attached with any good wood vice. The theory behind using a
crimp on connector is that if this doesn't work, my original cable is not
damaged, and I can go back to the original setup.

Having done all that, I couldn't be bothered to check the dev notes for
power consumption so I plugged it in and it works like a charm to this
day. 

In a mac II, everything should work the same. Be careful with the ID's of
the drive, and ensure that the terminating resistors on both drives are
intact. I did not try this without the terminating resistors but it
seemed logical that if I am splitting the SCSI chain, that the signal
should be terminated at all the ends.

Let me know if you have any more questions.

 TCP/IP routing LocalTalk-Ethernet.
Organization: University of Michigan ITD Consulting and Support Services
Lines: 27
NNTP-Posting-Host: stimpy.css.itd.umich.edu

Here is the story:
I have a network with 4 Macs on Localtalk. One of them has an
Ethernet Card, and is currently connected to a NeXT . The NeXT is connected
to the internet over SLIP running on a 9600 baud modem.

Currently, we can telnet from the Mac w/ Ethernet to the NeXT,
and then telnet out again to the rest of the world.

What we want to know is if there is some sort of hardware that
will route telnet sessions from the Localtalk Macs to the NeXT
via the Ethernet Mac. From what we have heard, AIR doesn't do
the trick.

Software solutions would be good too, but my impression is that
there aren't going to be any.

Our immediate interest is to be able to get to the NeXT and telnet
out again. The SLIP connection doesn't allow us to assign IP numbers
to machines, so everyone shares that 1 number...oh well...

thanks in advance.

Well Bill, There are 2MB soldered on the logic board and 2MB in the RAM
expansion slot giving you 4MB. The only thing you can do to upgrade to
the maximum Ram is to remove the 2MB expansion and install a 6MB expansion,
giving you a total of 8MB which is the max on a 170....You can try calling
TechWorks, or any other memory vendors out of MacWeek, MacWorld...etc....

Benchmarks are for marketing dweebs and CPU envy.  OK, if it will make

The point being the processor speed is only one of many aspects of a
computers performance.  Clock speed, processor, memory speed, CPU
architecture, I/O systems, even the application program all contribute 
to the overall system performance.
