- August 13, 1981 was a day that had
- an enormous impact on the future of
- home computers. IBM announced the IBM
- 5150 PC Personal Computer, in New
- York. The PC featured a 4.77 MHz Intel
- 8088 CPU, 64 KB RAM (expandable to 256
- KB), 40 KB ROM, one 5.25-inch floppy
- drive (160 KB capacity), and PC-DOS
- 1.0 (Microsoft's MS-DOS), for about
- $3000. It also included Microsoft
- BASIC, VisiCalc, UCSD Pascal, CP/M-86,
- and Easywriter 1.0. A fully loaded
- version with color graphics cost

- Microsoft began work in September
- on a graphical user interface for
- MS-DOS, initially called Interface
- Manager, because it would effectively
- hide the interface between programs
- and devices like printers and video
- cards. This was the beginning of
- Windows.

- The greatest moment in computer
- history (in this writer's humble
- opinion) came on January 18, 1982,
- when Commodore Business Machines
- announced the Commodore 64, showing a
- prototype at the Winter Consumer
- Electronics Show. It featured a 6510
- processor, 64 KB RAM, 20 KB ROM with
- Microsoft BASIC, custom SID sound
- chip, 8 sprites, 16-color graphics,
- 40-column screen, for $600.

- The C-64 was the first personal
- computer with an integrated sound
- synthesizer chip. Thanks to a well-
- integrated series of chips designed by
- MOS, the C-64 proved to be a very
- capable sound and graphics machine,
- often credited with starting the
- computer demo scene. Early C64 ads
- touted this, boasting "You can't buy a
- better computer at twice the price."

- In February, Intel introduced the
- 6 MHz 80286 microprocessor, using a
- 16-bit data bus, that could access 16
- MB of memory, or 1 GB of virtual
- memory. The PC, using Intel's 80x86
- technology, would grow into the
- dominant hardware platform family. Due
- to monopoly issues, IBM made its
- design generally public domain. The
- first IBM PC clone, the MPC, is
- released by Columbia Data Products in
- June. However, IBM kept its Basic
- Input/Output System (BIOS) a well-
- guarded secret. For some time, "IBM
- Compatibles" were neither.

- In Shreveport, Jim and Judi

- for a software-starved nation.
- Softdisk Monthly was filled with

- Atari introduced the 1200XL home
- computer in January, 1983, with 64 KB
- RAM, and 256 color capability, and a
- price of $900. Meanwhile, Commodore
- Business Machines sold the 1,000,000th
- VIC-20 computer, and introduced the
- SX-64, the first color portable
- computer. Weighing in at 10.5 kg, it
- incorporated a 5-inch color monitor
- and one or two 5.25 inch floppy drive,
- for $1600.
