Macintosh / Macintosh 128K

The computer that gave us it all!
• 128K of memory - at that time most computers had 64K of memory.
• Designed as a computer "appliance" - no need to add anything inside.
• Had a single sided 400K drive - at that time most computers had 180K single sided drives.
Debuted officially at $2495 on January 24th
MacWrite and MacPaint was bundled with the Macintosh

The now famous 1984 commercial which launched Macintosh from Chiat/Day is available from their historical page!
I'm pleased to present my Macintosh! (After a long search...)

It is proper to call the Macintosh by Macintosh or Macintosh 128K. Once the Macintosh 512K came out, it was important to come up with some modified name. If you say you have a Macintosh nowadays, most people will not think of this model.

 

The Macintosh 128K is used today yet for word processing, painting, telecommunications and the like. 128K of memory is still useful and enough for many tasks if you play by the Mac 128K's rules. The make sure you have two disk drives, otherwise the disk swapping will drive you nuts.

This is the only Macintosh where memory could be an issue. Using the basic applications (MacWrite, MacPaint, etc.) allows this computer to be useful. IF those applications went away, the Macintosh would just be used as an aquarium!

 

The Macintosh came with a bunch of industry firsts!
• 1984 - Graphical User Interface
• 1984 - Built-in LAN networking
• 1984 - Built-in sound
• 1984 - 3.5 inch floppies
• 1984 - Self-configuring LAN networking
• 1984 - Keyboard bus
• 1984 - Desktop metaphor
• In 1984, Apple took the pioneering work on the graphical user interface done at Xerox PARC and turned it into a
commercial success with the original 128K Macintosh.
• In 1984, Apple introduced the AppleTalk network, a self-configuring local area network technology.

Third-party companies have created a SCSI add on board which will complete the transformation of the Macintosh 128K to a Macintosh Plus. The other way was to obtain an Apple upgrade kit which consisted of the Macintosh Plus logic board and new case (the back part only.)

Apple's recommended System Software version: System 2.0 and Finder 4.1 (Macintosh System Software 0.3 & 0.5)

For AppleShare use: Can not be used as an AppleShare file server or workstation.

Below the software chart shows the AppleTalk Version as n/a. I have not successfully networked a Macintosh 128K on an AppleTalk network. The Macintosh 512K will work, the Macintosh 128K won't.  It must be a memory issue. :(

I have printed from a Macintosh 128K to a LaserWriter Plus. This is the only bit of "networking" the Macintosh 128K can do!

For telecommunications use: Can use 9600 baud modem or lower, anything higher may cause problems. Stock Macintosh cannot be placed on the Internet, Internet needs 4MB of RAM, possible with a memory upgrade.

Hard Drive use: One of the best expansion options for these older Macs was a hard drive which attached to the floppy port. It required a special INIT. The INIT and hard disk were called the HD20. Unfortunately the Macintosh 128K cannot use this drive. My testing confirmed this. :(
