Hello!
First, happy holidays.
I have a Classic II with a error. Sometimes turn on and appears a
floppy with the ? symbol. But sometimes appears a sad Mac with the
core: 0000000E (up) 00004000 (down). I heard a littles beeps, but
maybe is the HD.
This error indicates a RAM error. You probably have some bad or marginal
RAM in there, or...
I open a few days ago and I saw the battery liquid for everywhere, and
the place where the battery is hold, was missing.
This battery leakage might be causing the problem. First thing is to get
this all cleaned up. You can remove the logic board and use a mild soap
and something like a toothbrush to get it off, then let it dry for a day
or so. Make sure the RAM chips are clean too, as well as the connectors.
So, basically I need a few thinks, hope someone could help me:
- A diagram or photo of the battery zone to see if I could put it again.
You can see an image of the logic board with the battery holder just to
the left of the power plug at
http://farm4.static.flickr.com/3335/3409373549_cc611571ec.jpg . If the
housing and all that is missing, it'll take some doing to get it back in
again. You might have to use an external enclosure and use different
batteries to match the voltage, and solder the wires in.
- Where I can find a floppy for this mac? I tried to put a Performa
6400 floppy and the hole don't fit, and well, I get a sad Mac. If
someone have one or know about one, please, let me know.
If by floppy you mean disk, any floppy disk should work. The Classic II
has a Superdrive capable of using HD floppies, which are ubiquitous.
The drives are the type that are known as Auto-Inject drives. These have
no door flap and are common in the older Macs. You'll need to find one
like it for it to work properly, the holes don't line up otherwise.
- There's a way to save the system in a PC with floppy. I'm looking
for the disk to.
You can use something like HFVExplorer on Windows to access Mac HD
floppies, as well as rawrite and similar to write raw disk images. My
personal preference is to get a Mac emulator of some sort going and use
it as a go-between. Really simplifies things and even supports stuff
like Ethertalk file sharing.
OH, and in the history of Apple, wich Mac has most value: Mac Plus or
Mac Classic? I'm thinking to get a Plus to, but maybe sell this one.
In general, neither has a lot of monetary value. Classics were sold by
the truckload to schools and are pretty readily available. Pluses also
sold pretty well and don't have a lot of real rarity unless you're
looking at a particularly nice one, maybe in original box with original
accessories and such.
Beyond that, it depends on if you want one to actually use for something
or one to have on your desk as a showpiece. The Mac Plus was the third
Mac made, and the first that really hit its stride for capability and
expandability (good serial ports, 1 MB of RAM standard, 4 MB max, SCSI,
etc). It'll always be remembered that way and might be cool to have around.
The Classic, on the other hand, could be thought of as a "Macintosh Plus
Plus". It retains pretty much everything about the Plus (including
ability to run the first System softwares if you wanted) but adds a
Superdrive which greatly eases using with modern PCs, ADB for much
greater keyboard and mouse compatibility, a ROM disk boot for fun and
diagnostic, and it's supposedly a little faster with a faster SCSI bus
too. I've successfully gotten my Classic onto the internet with a
SCSI->Ethernet adapter and it's fun. Done some light word processing and
such on it.
Kind regards,
Abel.
Hope this helps!
Scott
