The Acorn Eurocard systems were a series of modular microcomputer systems based on rack-mounted Eurocards developed by Acorn Computers from 1979 to 1982, aimed primarily at industrial and laboratory use, but also home enthusiasts. The experience gained in developing this modular system strongly influenced the design of Acorn's first all-in-one home computer, the Acorn Atom, released in March 1980; and also much of the circuitry in its successor, the BBC Micro, first shown in late 1981.

| - The Acorn Eurocard systems were a series of modular microcomputer systems based on rack-mounted Eurocards developed by Acorn Computers from 1979 to 1982, aimed primarily at industrial and laboratory use, but also home enthusiasts. The experience gained in developing this modular system strongly influenced the design of Acorn's first all-in-one home computer, the Acorn Atom, released in March 1980; and also much of the circuitry in its successor, the BBC Micro, first shown in late 1981. Acorn's final rack-based machine was the System 5, released in late 1982. The Eurocard business was then sold on to one of its principal resellers, Control Universal Ltd, which continued to develop various cards for industrial use based on the Acorn-standard bus during the 1980s, but ultimately went into receivership in 1989.

- El Acorn System 2 se ofreció como un sistema por Acorn Computers desde 1980. Fue el sucesor al Acorn Microcomputer (renombrado después como Acorn System 1). El sistema tenía cuatro tarjetas de circuitos integrados Eurocard montadas en un armazón de 19 pulgadas sobre una placa base de 8 bahías, más un teclado externo opcional. Las cuatro tarjetas con circuitos integrados (TCI) tenían:
* Una tarjeta con la CPU, conteniendo un microprocesador 6502 a un 1 MHz, la interfase del teclado, y una ROM de 2K con el sistema operativo de casete (La tarjeta con el 6502 se podía cambiar por una con un 6809.)
* Una tarjeta VDU (Video Display Unit), que proporcionaba una presentación estándar de 40×25 caracteres de teletexto, basadas en un controlador CRT MC6845 y un generador de caracteres de teletexto SAA5050.
* Una tarjeta enlace para conectar un casete.
* Una tarjeta de memoria RAM de 4K y una ROM de 4K con BASIC. Se podían añadir 4K más de RAM, y una ROM extra de 4K con rutinas de punto flotante y funciones científicas. La tarjeta de la interfase de la CPU y del casete fueron las mismas tarjetas que se usaron en el System 1, pero con el miniteclado y la minipantalla LED del último sin usar. El sistema se podía ampliar con cualquiera de las Eurocards estándar de Acorn para añadir más funcionalidad. En 1982 se vendía por 320 libras (1200 euros de 2022), o 480 libras (1900 euros de 2022) con la fuente de alimentación, más 136 libras más (525 euros 2022) por el teclado opcional. (es)
