- Itautec I7000
-
- driver by Felipe C. da S. Sanches <juca@members.fsf.org>
- with tech info provided by Alexandre Souza (a.k.a. Tabajara).
-
- The portuguese Wikipedia article available at
- http://pt.wikipedia.org/wiki/Itautec_I-7000
- also provides a technical overview of this machine:
-
- The I-7000 was the first computer manufactured by Itautec
- (http://www.itautec.com.br/pt-br/produtos). It was originally an 8 bit CP/M
- computer that became an IBM PC-XT clone in later hardware revisions which
- took the "I-7000 PC-XT" name.
-
- * Released in 1982
- * Operating System: SIM/M / BASIC
- * CPU: National NSC800 D-4 at 4,00 MHz
- * Memory: 64KB to 128KB
- * keyboards: 80 keys (with a reduced numerical keypad and function keys)
- * display:
- - 40 X 25 text
- - 80 X 25 text
- - 160 X 100 (8 colors)
- - 640 X 200 (monochrome, with an expansion board)
- - 320 X 200 (16 colors, with an expansion board)
- * Expansion slots:
- - 1 frontal cart slot
- - 4 internal expansion slots
- * Ports:
- - 1 composite video output for a color monitor
- - 2 cassette interfaces
- - 1 RS-232C serial port
- - 1 parallel interface
- * Storage:
- - Cassette recorder
- - Up to 4 external floppy drives: 8" (FD/DD, 1,1MB) or 5" 1/4
- - Up to 1 external 10 MB hard-drive

- ROM address | Originally dumped value | Manually fixed value | Comment
- 0x06A2 | 0xF7 | 0xFE | This is a fix to the upper right portion of a 2x2 tile image of a big filled circle
- 0x06A3 | 0xF7 | 0xFE | This is another fix to the same tile (character value: 0xD4)
-
- Also, characters 0x05, 0x06, 0x07 and 0x08
- as well as lowercase 'x' (0x78), uppercase 'Y' (0x59)
- may contain corrupt data, but we can't be sure,
- unless we find another Itautec I7000 computer and
- redump it's ROMs to double-check.
