Dataindustrier AB

From Wikipedia, the free encyclopedia

Dataindustrier AB or DIAB was a Swedish computer engineering and manufacturing firm, founded in 1970 by Lars Karlsson and active in the 1970s through 1990s. The company's first product was a board-based computer centered around a specific bus named Data Board 4680. This unit was used for automatic control in several Swedish industries as would be almost all of DIAB's computers. DIAB is mostly known for engineering the ABC 80, the first Swedish home computer, manufactured by Luxor AB.

They would subsequently develop all the ABC-models (ABC 800, ABC 1600 and ABC 9000) before rebranding their own make of the ABC 9000 as DIAB DS-90 and develop a series of Unix-compatible computers, using code licensed from AT&T Version 5 Unix release, but with a unique in-house kernel using the brand name DNIX. DIAB would continue to provide OEM services past Luxor AB, the most prominent probably being the entire Unix server product line from Cromemco.

The compiler technology developed by Tomas Evensen at DIAB was bought by Wind River Systems who still refer to it as "the DIAB compiler", whereas the Unix computer support and customers was acquired by Bull Computer in 1990 ending the history of the company.

[edit] Product line

[edit] Card-based microcomputers

1974: Data Board 4680 - the number is a short form of the three microprocessors supported by the bus of this system: Intel 4004, Motorola 6800 and Zilog Z80. Eventually only Z80 was ever used in this product.

[edit] Home and office computers

1977: 7S "Seven S" a combined monochrome terminal and computer built on the Data Board 4680 bus and a Z80 processor.
1978: ABC 80 a Z80-based monochrome home computer.
1983: ABC 800 an enhanced office and home computer, 32 KB RAM, also based on Z80, with color graphics.
1983: ABC 802 a variant of ABC 800 with 64 KB RAM whereof 32 KB were used as a RAM disk.
1983: ABC 806 a variant of ABC 800 with 160 KB RAM whereof 128 were used as a RAM disk.

[edit] UNIX computers

1985: ABC 1600 a personal computer running ABCenix.
1985: ABC 9000 really a DS90 in disguise, running DNIX.
1985: beginning of the DS90-line
- DS90-00, DS90-10, DS90-11, Motorola 68010-based UNIX servers intended for use via terminals.
- DS90-20, DS90-21, quad Motorola 68020-based computers
- DS90-30, DS90-30S, DS90-31, dual Motorola 68030-based computers
- DS101, actually a DS90-31 with exterior design by the famous pop-artist Richard Hamilton
- DS90-41, DS90-45, DS90-47, Motorola 68040-based computers
the DIAB line, these are actually partly rebranded DSnn-computers:
- DIAB2320, DIAB2340, Motorola 68030-based sequels to the DS90-31
- DIAB2420, DIAB2440, DIAB2450, Motorola 68040-based sequels to the DS90-47
- DIAB9030, DIAB9031 - even later computers of unknown construction
OEM products based on DIAB UNIX computers:
- Dynatech Computer Systems (Cromemco) DCS-1/200: based on DS90-30. The Cromix UNIX dialect used in these systems is likewise simply a rebranded DNIX.
- Dynatech Computer Systems (Cromemco) DCS-1/300: based on DS90-31
- Dynatech Computer Systems (Cromemco) DCS-1/400
- Dynatech Computer Systems (Cromemco) DCS-4/300: based on DIAB2450
- Dynatech Computer Systems (Cromemco) DCS-4/400: based on DS90-41
- Ohio Scientific - this company is known to have made at least one OEM computer based on DS90-00 hardware, model number(s) unknown.
- Norsk Data - also made a DS90-00 OEM computers, likewise details unknown.
- ISC Systems Corporation DNP-10: based on DS90-10
