Portable - the first portable Macintosh -

What
the buyer says: "Ottima transazione.
rapida e cordiale."
If you do not have a original power supply for
the Mac Portable, but you can use a PowerBook
100-series AC adapter to run the Portable without
the internal lead-acid battery. Do this only on
your own risk! However, you will lose PRAM settings
if you unplug the power (date, time, cache size,
etc.)
"Do not trust a computer that
you cannot lift." Steve Jobs, 1984
Jef Raskin took this saying to heart as he designed
what would become the Macintosh, an all in one
computer, which could be easily moved. The final
product weighed a little more than 16 pounds.
In April of 1986, the Apple board decided to create
a battery-powered BookMac. After Jobs left later
in the year, the project continued, until the
Macintosh Portable was released.
The Macintosh Portable was Apple's first attempt
at a true portable computer. There are two versions,
the original, and the later, backlit model. The
Portable was the first Mac to ship with a preformatted
hard drive (and the only portable Mac with a 3.5"
hard drive) and a preinstalled operating system.
Along with the Mac IIci, it was one of the first
Macs to user surface mount technology. The Portable
was upgraded with a backlit screen; more, less-expensive
RAM (2-4 MB standard); and a lower price in February
1991. The Active Matrix screen didn't have the
blurry display of conventional displays. In fact,
the display was crispy clear, and looked beautiful
when used in daylight. The Portable did have problems
with dark rooms though, until a 1991 upgrade added
backlighting.
The Portable featured a clamshell design with
the same easy-access style of case that other
Mac's of that time had. Pressing two places on
the rear of the computer allowed the rear half
of the case top to come off, revealing (from left
to right) the battery compartment, expansion slots,
and 40MB hard drive. There was only one problem
with the Portable, which unfortunately led to
its demise; it just wasn't portable. Weighing
in at 12 lbs., few people had the patience to
lug it around anywhere, despite all of its great
features.
The Portable came with a Lead-acid gel/cell battery,
similar to those found in car batteries, that
could run a anywhere from 6 -12 hours! This is
unheard of even today, as you it is hard to get
even 2 hours of usage from today's PowerBook batteries.
The Portable also included a 40 MB SCSI HD manufactured
by Conner. The HD could spin down and sleep, but
sacrificed price for performance, costing twice
as much as a desktop HD of the same size. It supported
to internal hard drives, and an external one.

Tips for the Apple Portable from www.lowendmac.com:
- One user has reported success replacing a
dead Conner CP-3045 hard drive with a standard
Conner CP-3044 that had been formatted under
System 6.0.8.
- You can use a PowerBook 100-series AC adapter
to run the Portable without the internal lead-acid
battery. However, you will lose PRAM settings
if you unplug the power (date, time, cache size,
etc.)
- Godwin <godwin@unixg.ubc.ca> says,
"If the acid battery dies, one can bypass
it and convert the Portable into a luggable.
One needs 2 AC adapters -- the original one
and a 9V DC adapter. Take out the 9V DC battery
and replace it with a 9V 1A power adapter. Then
remove the battery and cover (there is a switch
at the battery cover which we need to disable).
Plug the two adapters in and viola! one of the
sleekest Macs on anyone's desktop!"

Zitat
des Käufers: Ich konnte das Paket heute
abholen. Ist ein sehr schönes Gerät,
habe heute frei, da werde ich mich heute eine
Weile damit beschäftigen.
1989 stellte man den ersten tragbaren Macintosh
vor, den Mac Portable. Das Gerät basiert
auf dem Ur-Mac, hat eine 68000-CPU mit 16 MHz,
1 MB auf dem Motherboard fest verlötet, durch
spezielle RAM-Karten (die es nur von Apple für
sehr viel Geld gab), konnte der Portable auf max.
9 MB aufgerüstet werden. An Massenspeicher
gab es entweder zwei 1,4 MB-Floppys oder eine
Floppy und eine Festplatte (je nach Geldbeutel).
Intergrierter Trackball, ein Steckplatz für
ein (optionales) internes Modem und ein ProzessorDirektSlot
(PDS), der für niemals hergestellte Karten
vorgesehen war, rundeten das Gerät ab.
Als Anzeige diente ein 10 Zoll großes,
nicht hintergrundbeleuchtetes Aktivmatrix-Display
mit 640 x 480 Pixeln (S/W). Zwar war es sehr gut,
doch erst die zweite Generation der Portables
(1990) bekam es hintergrundbeleuchtet. Als mobiler
Stromspender diente ein Bleiakku, der langen netzlosen
Betrieb ermöglichte (12 Stunden!). Aber all
das hätte die Mac-Gemeinde ja noch irgendwie
hingenommen, wenn nicht der immense Preis gewesen
wäre. Über 15.000 DM für einen
tragbaren Mac, der eigentlich 5 Jahre alt war,
das war den Anwendern einfach zu teuer. Außer
bei Sammlern ist der Portable nie beliebt gewesen.
Die technischen Innovationen wie Trackball (für
Linkshänder auf die andere Seite der Tastatur
versetzbar) oder Abschaltung der Festplatte und
des Displays nach längerer Inaktivität
halfen da leider auch nicht.
Ausserdem ist zu bemerken, dass der Protable einer
der ersten Rechner mit Power Managment war. Der
Portable schaltet sich z.B. ein, wenn das Faxmodem
einen Anruf meldet.
