Apasal Lisa tak masuk dalam list? Sedangkan Lisa nie personal computer pertama yang mula mula pakai GUI.

Remy_3D awak maksud kan "Local Integrated Software Architecture" (LISA).....

The Lisa is the first commercial computer with a GUI, or Graphical User Interface. Prior to the Lisa, all computers were text based - you typed commands on the keyboard to make the system respond. Now, with the Lisa, you just point-and-click at tiny pictures on the screen with a small rolling device called a 'mouse'.

This was an amazing advancement in a user-friendly computer system, but Apple didn't invent the idea of the GUI. Xerox's Palo Alto Research Center (PARC) originally developed the GUI and the mouse, but their 'Alto' computer was far too expensive, and sold poorly.

Although Apple spent an incredible amount of time and money developing the Lisa, four years and $50 million, it turned out to be an unpopular system, due to its high price and few available software applications. Additionally, it was rather slow, as the large and complex operating system was a huge burden on the 5MHz CPU.

Introduced:    January 1983
Released:       June 1983
Price:            US $9,995
How many?    100,000 in two years
CPU:              Motorola 68000, 5 MHz
RAM:            1 Meg
Display:         12" monochrome monitor  720 X 364 graphics
Ports:            parallel, serial  mouse port
Expansion:     three internal slots
Storage:       Two internal 871K 5-1/4 inch floppy drives optional external 5Meg 'ProFile' hard drive
OS:              Apple Lisa GUI

wuu best tu..ada lagi ke software nye..

After around 6,500 units were sold, Apple upgraded the Lisa and re-introduced it as the cheaper Lisa 2, seen above. Two versions were available, the Lisa 2/5 and the Lisa 2/10, which has either an external 5 Megabyte or an internal 10 Megabyte hard drive. Also, the two 5 1/4-inch "Twiggy" floppy drives were replaced with a single 3 1/2-inch Sony floppy drive. The new drive only held half as much data as the old one, but was much more reliable.

The final blow came about a year later, when Apple again changed the Lisa 2. It would now be known as the Macintosh XL, and run the Macintosh operating system instead of the original Lisa OS.

Sales did pick-up, but Apple discontinued the Lisa line with 100,000 units sold after 2 years. By this time, the popular (and cheaper) Macintosh line of computers was available, of which Apple sold 70,000 in the first 3 months.

The Lisa is very technician-friendly - once the back panel is removed, the entire electronics assembly slides out in one piece, and the circuit boards are easily removed from their sockets.

The power supply is just as easy to remove and replace, it is held in place by a single thumb-screw, and slides out with just a tug.
