The ENER 1000 was a Portuguese computer released in 1982.[1][2][3][4][5] It had 64 KB RAM and two 5 1⁄4-inch double-density floppy disk drives.[6] It ran the CP/M operating system.
The machine was developed on Universidade de Coimbra and sold through Enertrónica after 1982.[3][7] More than 500 units were sold.[8] It came with software for stock management, salary processing, and accounting.
In 1983 the machine was awarded the 1st prize for creativity at Endiel (Encontro Nacional para o Desenvolvimento das Indústrias Elétricas e Eletrónicas).[9]
In 1984, a dozen of ENER 1000 were distributed to some secondary schools.[10][11] In 1985 the ENER 1000 project ended.[12]
Characteristics
The machine was based on eurocard cards (10 x 16 cm) connected to the motherboard using up to 8 DIN 41612 connectors. The desktop box measured 50 x 36 x 15 cm and could house up to 8 cards. There were two internal 5 1⁄4-inch double-density floppy disk drives (1.6 Mb capacity).
Minimal configuration
The minimal configuration used only 4 slots:
- CPU card with a Motorola MC6809 processor and 2K EPROM
- 64/128 KB DRAM card
- double serial interface card
- floppy disc controller card
The computer could function as a multi-station machine, supporting up to 4 users in 7 terminals.
Expansion modules
Some custom built modules were available for expansion:[1]
- FPU
- 6809 CPU with 4K EPROM, 2K RAM e timer;
- 16K static RAM/ROM;
- alphanumeric and graphic unit for spectral plots;
- light pen;
- fast ADC for Nuclear Physics applications;
- four 8bit DACs;
