#+Title: VolksForth MS-DOS for Atari Portfolio
|
||
|
||
The Atari Portfolio is a portable, MS-DOS compatible palmtop computer
|
||
released by Atari in 1989
|
||
(https://en.wikipedia.org/wiki/Atari_Portfolio).
|
||
|
||
The Portfolio uses an Intel 80C88 CPU running at 4.9152 MHz and runs
|
||
"DIP Operating System 2.11" (DIP DOS), an operating system mostly
|
||
compatible to MS-DOS 2.11, but with some DOS 2.xx functionality
|
||
lacking and some internal data structures more compatible with DOS
|
||
3.xx. It has 128 KB of RAM and 256 KB of ROM which contains the OS and
|
||
built-in applications. The on-board RAM is divided between system
|
||
memory and local storage (the C: drive). The LCD is monochrome without
|
||
backlight and had 240×64 pixels or 40 characters × 8 lines.
