🎄💾🗓️ Day 9: Retrocomputing Advent Calendar - The Apple Lisa 🎄💾🗓️

The Apple Lisa, introduced on January 19, 1983, was a pioneering personal computer notable for its graphical user interface (GUI) and mouse input, a big departure from text-based command-line interfaces. Featured a Motorola 68000 CPU running at 5 MHz, 1 MB of RAM (expandable to 2 MB), and a 12-inch monochrome display with a resolution of 720×364 pixels. The system initially included dual 5.25-inch "Twiggy" floppy drives, later replaced by a single 3.5-inch Sony floppy drive in the Lisa 2 model. An optional 5 or 10 MB external ProFile hard drive provided more storage.

The Lisa's price of $9,995 (equivalent to approximately $30,600 in 2023) and performance issues held back its commercial success; sales were estimated at about 10,000 units.

It introduced advanced concepts such as memory protection and a document-oriented workflow, which influenced future Apple products and personal computing.

The Lisa's legacy had a huge impact on Apple computers, specifically the Macintosh line, which adopted and refined many of its features. While the Lisa was not exactly a commercial success, its contributions to the evolution of user-friendly computing interfaces are widely recognized in computing history.

These screen pictures come from Adafruit fan Philip " It still boots up from the Twiggy hard drive and runs. It also has a complete Pascal Development System." …"mine is a Lisa 2 with the 3.5” floppy and the 5 MB hard disk. In addition all of the unsold Lisa machines reached an ignominious end."

What end was that? From the Verge -

In September 1989, according to a news article, Apple buried about 2,700 unsold Lisa computers in Logan, Utah at a very closely guarded garbage dump. The Lisa was released in 1983, and it was Apple’s first stab at a truly modern, graphically driven computer: it had a mouse, windows, icons, menus, and other things we’ve all come to expect from “user-friendly” desktops. It had those features a full year before the release of the Macintosh.

🎄💾🗓️ Day 3: Retrocomputing Advent Calendar presents the Commodore VIC-20! 🎄💾🗓️

The VIC-20 ⌨️📺🕹️, released in 1980 by Commodore, was the first computer to sell over a million units. It had a 6502 CPU running at 1 MHz, 5 KB of RAM (expandable), and displayed up to 22 characters per line on a color-capable screen. An affordable and friendly computer, the VIC-20 was great at games and basic programming and was supported by a library of software and peripherals. It connected to TVs for display and included Commodore's BASIC interpreter for programming. Its success allowed other computers like the Commodore 64 to make its mark.

And since this is a #firstcomputer celebration here's a fantastic story from Jeff -

My first home computer was the Commodore VIC-20. I must have been in second grade (1986/1987). My Dad was working somewhere away from home, but one weekend Mom drove us two kids to spend the night at the motel that was his home base.

He had bought this computer, the VIC-20, and hooked it up to the hotel TV. I remember entering the program pictured below (probably Mom typed it in, actually) and being blown away by the birds flapping their wings across the screen.

The other distinct memory I have is the next morning my folks woke me up and asked whether I was hungry. No, I very much wanted to play with the VIC-20, so I made up the most obvious word that came to mind: "No, I'm Vic-y". I think they were very puzzled. We probably went and had breakfast regardless of whether we wanted to see the birds flying again.
