More likely than not, you have a greyscale monitor (as someone else
already suggested). This is more common on older Macs, especially if
the monitor is large (i.e. 16"+). Other reasons as to why you see
grey (that I have not yet suggested, because I don't think it's the
case) include problems with your monitor's cable and with the video
card itself.

The video card on your machine supports color. Otherwise, your
Monitors control panel would not show the options for it.

I hope this helps.

Just recently someone gave me the following PC:
Macintosh Plus (model #M0001A)
 
[snip]

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.

Yes, your Mac is awaiting for a bootable floppy disk. Back then,
hard drives were cost prohibitive, so computers (Macs and PCs) always
booted from floppy disks. Macs were ahead of its time by using the
3.5" floppy drive instead of the more-common 5.25" at the time.

Apple also had the foresight to include a SCSI port on your Mac Plus.
With it, you can attach a modern (or not), external, SCSI hard drive
to it. (By "modern", I mean that you can buy a SCSI hard drive today
to use on the Plus.)

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?

Processor (CPU): Motorola 68000 @ 8MHz
Maximum RAM: 4MB
More info: http://www.info.apple.com/applespec/applespec.taf?RID=4

It was originally introduced in 1986. Like all Macs (including those
made in 1984), you use it with a graphical interface, unlike DOS
(i.e. no command line interface). In other words, you use the mouse
to navigate instead of typing in DOS commands at the prompt. (If you
don't have a mouse, you need one. You didn't say that you had one.)

If you say, "Only 8MHz!," then let me tell you...I'd say that the
Plus can rival the speeds of an 80386 with Windows 3.1 and even some
'486s. Back then, you were just more productive with Macs
*PER-I-OD!*.

[snip]

on the net whereby I can download operating system(s) and other software?

First off, you can use System 1.1 (1986) up to System 7.5.5 (1996) as
the operating system to boot the Plus. However, since you are
limited to floppy disk booting (with the hard drive), you need to
first find out what kind of floppy drive you have (400K or 800K).

If you see a red beam in the floppy drive hole after turning on the
Mac, then the floppy drive is 400K. Otherwise, it most likely
supports the 800K disks (as well as 400K). It is RARE to find one
with a 1.4MB floppy drive, especially since it was not made by Apple.
(Note that both 400K and 800K disks have only one hole on the disk.
Disks that are 800K are denoted "DD" or "Double Density" and can also
be used as 400K--single density--disks.)

If you have a 400K drive, then go for an OS prior to System 6.
Otherwise, use System 6. You can find them here:

http://www.mac512.com/ssdl.htm

If you are downloading the system software from a PC, then you have a
problem, because PCs do not make Mac disks. (Note that Macs can read
PC disks, with the exception of special cases.) Instead of my
explaining the complicated steps to get the disk Mac bootable from a
PC, my suggestion is to have someone with a Mac make you a disk.

I hope this helps.

My first Mac, an LCII, had the same symptoms which you described although my
description at the time was that the noise was like a jet taking off. It was
diagnosed as a faulty sound chip necessitating a replacement motherboard.

Keith

Is there anyone on this list who knows about Imagewriter II printers?

Please contact me off-list. I especially need operating and repair manuals.

Thanks,
Paul

Didn't very early operating systems require a 'color' extension? I seem
to remember the icon as a prism with light rays passing through it ...

This is the only video card in the computer. The monitors control panel
will let me choose up to 256 colors, but it still displays only gray.

If you place a color video card in, all Mac II for factors support
color.

To everyone out there. Thanks, I have the manuals now..

Thanks,

Stuffit does no reformatting of your data. The data on the Mac side is
identical to the data from the PC. If you want the data to change, get
Maclink Plus.

Mike

Now that I've put my foot in my mouth by blabbing about a rebate for a
version of Stuffit that works only on PC's, I have a question. 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?

My SE30 lost all contact with the outside world. No printer or modem
connection possible.

I was told that the chip on the main board was probably bad and needed
replacement.

I just learned that there is a chance that a minor repair may cure the
problem without a chip replacement.

Can I fix it if it is a minor problem and if so how do I do it.

First try Command-Option-Shift down while selecting the Chooser from the
Apple Menu, releasing the keys only after you hear a system beep. Restart,
select your output device in the Chooser, and attempt to use it. If the
problems remain, zap the PRAM by restarting once more, holding down
Command-Option-P-R from as soon after the screen blacks out through to the
third startup chime...

Hello All

I have a 512k Mac that still works great, but the little guy is taking up
space that I need in the house. I've been wanting to keep it because I
heard a rumor that some of the early 512k's have signatures of; Jobs,
Wozniak, and of the original production line crew.

Is this true? Does anyone know the span of serial numbers of those 512's
that have been signed? I'm just afraid to open the thing up and
accidentally break something.

All 512's should have the signatures. The signatures actually went on to appear in
the Macintosh Plus and SE before the case moulds which bore said signatures wore
out. My "platinum" Mac Pluses both contain the signatures which are faintly
moulded on the inside back of the case. ( I never noticed them until I
specifically looked for them.) If in the end, you insist on getting rid of your
512k, I'm sure there would be many readers on this list willing to relieve you of
them.

Adam.

The trouble is (and this will sound
familiar if you read the Compact Macs list) is when I insert a floppy, I get a
'Disk Unreadable' error. This happens about 5 out of six tries using both HD and
800K disks. (I actually seem to have greater sucess with the 800Ks) I inserted a
HD disk with nothing important on it and said Yes when prompted to initialise.
The resulting disk now always works (with only one failed attempt).

My guess on this one, is that the collision with the slate floor has
slightly shifted the position of the heads. This would mean that it could
read any floppy it had written (same error, read and write), but have
trouble with discs from other drives. I have heard that some drives have
trouble when reading a cold disc that was written to when hot, so you might
try warming or cooling discs before reading them. Keeping in mind of course
that too much heat will wreck the disc and any condensation would not help
the drive.

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 ?

Failing that, you could try dropping the other mac from the same height
onto the same floor !

good luck, Paul

Dear Maccers,

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?

Thanks, Jan Kistemaker

All of the Mac 128K & 512K units have the signatures inside.

Actually you can boot a Mac Plus up from a floppy disk or a SCSI external
hard drive.

A lot of information on the Mac Plus is found here:

Free software downloads (System Software and applications) for the Mac Plus
is found here:

Macintosh Plus (model #M0001A)
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.

On Classic Macs Digest, you wrote:

Michael, you are absolutely right. Macs starting with the original 128k
through the earliest SE's had the signatures of the entire Mac Design Team
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
it open with the appropriate tools and there are at least 40 signatures in
the case. These are the design team signatures. This is testimony to Jobs's
saying that all great artists sign their work. Once again, the signatures
exist in all pre-SE Macs and in only the earliest of the SE Models. By
then, the mold for the case had worn out so they replaced it with a
signature-free case. Some of the obvious sig's are those of Jobs and Woz,
Jef Raskin (The true creator of the Mac), The guys that wrote the original
finder, and Bill Atkinson (QuickDraw and MacPaint Author).

I'll be thankful for any help or insight.

I'm glad to have helped. Anything for a Mac Enthusiast.

"Flops before Gigaflops."

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?

I have a few of these neat machines, and while I expect the previous
answers (capacitors,fans) are probably the most likely, I thought I'd
mention that one of mine makes a nasty squeal (intermittently) from it's
monitor. Interestingly, the tone sometimes changes with the image on the
screen. At first I thought this signalled the imminent demise of the
monitor, but it's still going fine 2 years on...

btw. I've just discovered a great little energy saver called "Sleeper" that
can turn off the LCIII monitor (and spin down the drive). I was surprised,
as I hadn't thought a monitor that old would be Energy Star (or whatever
it's called !) compliant.

cheers, Paul
