Re: SE/30 Floppy drive (unreadable)

I have recently acquired a Performa 460, a/k/a Macintosh LC III or LC
III+, I believe.

This Performa seems to have a disconcerting (inconsistent) tendency
to emit a squealing or whistling noise during the start-up process.
Any idea what's causing this?

If it's not the speaker, power supply or fan, it could be the hard drive.

The way to tell is, disconnect both connectors to the hard drive, then turn the Performa on. If it's quiet, you know the drive has gone bad. Turn it off, hook it back up. Back up your data ASAP and replace the hard drive. I have heard hard drives make some pretty weird noises as they age, particularly if they don't get much use.

A replacement drive for that computer shouldn't be too expensive, and you can take the opportunity to increase your storage space.

Happy troubleshooting!
Rob

As a happy, inexperienced, and new SE 30 owner, which internet browser
would work best with my SE 30 running system 7.6 and where would I obtain it?

RDE

Trick question, an SE/30 cannot run system 7.6. All system versions after 7.5.5 require a 32-bit clean Mac. The SE/30 is not.

Well for those who have ever wondered about whether or not a Macintosh TV can see more than 8 MB of RAM, I guess I'd have to say that it cannot. In review, the Macintosh TV shipped with 4 MB on the board and a 1 MB SIMM in the slot, which could be swapped out for a 4 MB SIMM, giving it a grand total of 8 MB. I recently pulled a 32 MB SIMM from Quadra 660AV and stuck it in there. Sadly, the Finder recognized only 8 MB. I don't know why this is, but I guess that's just the way it is!

This really could be a much more potent machine if only one could get over this hurdle. At this time, the very best I can get is 24 MB by using RAM Doubler 2. Despite this apparent shortcoming, I still love my little black Mac! :-)

There are two great secrets to success in life.
1. Never reveal everything that you know.

I am a IIvx owner.

Though possible, upgrading this machine to PPC is a terrible idea.

The only upgrade I know of is a Sonnett Tech 68040 upgrade. But even if a PPC upgrade would be possible, your RAM and disk would need to be expanded.

Also compare your IIvi to a 7100, which looks like a IIvi but it has a genuine PPC mother board. They go for only $65 on ebay. I doubt if you can find an accelerator for less.

I would like to be able to run an occasional ppc-native application on my
Mac IIvi (68030/16mhz, 20/700), so I think about putting a ppc-upgrade card
into it's PDS. Now some tell it will be possible and some tell me it wont.
Is there anyone in the audience who can tell me the truth about this?

Help !! Frustrated at not being able to change the colour cartidge my daughter has broken the carriage unit of our Stylewriter 1500. Does anyone know of a source for a replacement - better yet does anyone have a broken 1500 they could salvage this from.

Cheers all,
Keith

P.S. I know these printers are cheap in the US now, but that is not the case in Belgium !

Just a few days ago, I came across a web page which contained the wiring schematics for various classic Macs. Stupidly I didn;t bookmark it and have since forgotten the URL. Does anyone know where it is?

Thanks
Adam.

I also would like to find out about the ImageWriterII. I downloaded the Service Manual in Adobe Acrobat from the Tech Manual web site (or was it FTP?) and wasn't overly impressed with the technical detail. It does have pretty good drawings , and exploded views, etc, though. Where would one go to find a detailed manual? I have 3 or 4 dead or injured IWIIs at home, and think I should be able to put together at least one working printer out of the whole bunch, if I only knew more.

Thanks,
Glenn

From: lawrie mcrae
Subject: MacIntosh Plus ??

Hello there:

Just recently someone gave me the following PC:
Macintosh Plus (model #M0001A)
Keyboard
Image Writer printer

I know nothing re the Macintosh machine, it has a 3.5 floppy drive out
front, I haven't opened it up yet to see the internals. When I power it up
I get an Arrow (upper left screen), and a Floppy symbol in the middle of
the screen.

I am assuming it wants to boot off a floppy, unfortunately I received no
software/disks with the machine.

Can anyone out there brief me on what I have here? E.g. where does it live
in relation to the PC world, namely is it a XT,AT,286,386, or 486? Is there
a source for software on the net whereby I can download operating system(s)
and other software?

Many thanks for time!

If you don't have a mouse to go with it, you won't find it useable even
with a boot disk. You should be able to pick up a mouse on eBay for $10 - $20.

Ira Adams

Not quite. Under some versions of the System existed a feature called 'mouse keys' this allowed you to use the numeric keypad to move the mouse cursor (thats the arrow you see in the top left of the screen). To enable it you press Command-Shift-Clear. The command key is the one just to the left of the space bar on the Mac Plus keyboard, and the Clear key is at the top-left hand corner of the numeric-keypad cluster (where the Num Lock key sits on the PC). Once activated, the 5 key on the keypad simulates a mouse click while the rest of the numbers move the cursor around (8-up, 6-right, 3-down-right etc.) This works on my Plus under System 6.0.8 and my SE/30 under System 7.1. Interestingly, the cursor movement on my Plus was rather snappy (so I recall, I don't actually have the Plus set up as of now) while it positively crawls on my SE/30. It's nowhere near as good as the mouse, and won't work until you've loaded up the Operating System (possible with the Easy Access Control Panel installed) but it _will_ work.

Etched into the back of the case. I have an original 128k that is a 1984
model (based on the serial number, manufactured in the 11th week of 1984)
and bears simply the name "Macintosh" on the back of the machine. I cracked

I have one of those too. How do you find the date from the serial number.

Say I take a data file on a PC and compress it with the PC version
of Stuffit. I put that compressed file on a diskette and move it to
a Mac, where I unstuff it, this time using, of course, a Mac version
of Stuffit. Is the file now in a form that makes sense to a Mac, or
is in once again in a form that makes sense to a PC?

Remember that BEFORE the compression on the PC, you would have already lost information for the Macs (e.g. resource fork). So, decompressing it on the Mac will get you what you started with on the PC.

I hope this helps.

I would also add that a good scsi drive to use with the Mac Plus would be a SCSI Zip drive. Although newer SCSI hard drives would work with the Mac Plus, the high speed of these drives would be wasted on a Mac Plus (because the Mac Plus would be unable to take advantage of these high speeds). A better alternative would be the SCSI Zip drive, which is slower than the current crop of SCSIs, yet faster than the original Mac Plus SCSI hard drives. This makes for a perfect match (and less expensive than buying a brand new hard drive).

Hi. This is the guy that was offering mice for 'shipping only.' I checked them out, and there are about 7, but all of them are 'ball-less.' I don't know if the balls are the same as any other types of mice, so that's what happened to my offer. I suppose they're useless.

If I regularly needed to read discs from other macs, then I think I'd try
very carefully to bend the arm the heads are on, perhaps with a known good
drive open beside me as a comparison. Bear in mind that at 135 tracks per
inch (I think) the movements should be very small. Still, if it's no good,
what have you got to lose ?

I'm planning on buying a new SuperDrive ($5.00) from a local retailer (as soon as
they reply to my emails). At this point, my existing (broken) drive
will become expendable upon which I'll be subjecting it to disassembly, a
thorough examination and a cleaning to determine the fault. I'll definately
look into the head alignment.

Adam.

Sorry, forgot to say, Thanks Paul.
