The ENER 1000 was a Portuguese computer released in 1982.[1][2]

It had 16Kb RAM and two 5" 1/4 double density floppy disk drives.[3]

It ran the CP/M operating system.

The machine was developed on Universidade de Coimbra and sold through Enertrónica after 1982. Only a few dozen units were sold.

It came with software for stock management, salary processing, and accounting.

In 1984 a dozen of ENER 1000 were distributed to some secondary schools.[4]

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 double density floppy disk drives (1.6Mb capacity).

Minimal Configuration

The minimal configuration used only 4 slots:

  • CPU card with 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;
  • local network node;
  • Winchester 5" 1/4 controller;
  • CRT and keyboard controller;
  • 8088 CPU;
  • synchronous serial ports (HDLC and SDLC);
  • 12 bit A/D and D/A converters;
  • DMA controller
