The A7000 and A7000+ were Acorn Computers's entry level computer based on the Risc PC architecture. Launched in 1995, they replaced some of the models of the Acorn Archimedes range. After the breakup of Acorn Computers in 1998, Castle Technology bought the rights to continue production of the A7000+. The A7000 used the ARM7500 system on chip which combined the separate ARM CPU, MMU, VIDC20 video chip and IOMD IO controller of the Risc PC into a single chip.

The A7000+ was launched in May 1997. It is an upgraded A7000 , the main changes were:

48MHz ARM7500FE with a built in floating point processor
8MB EDO memory
Bigger 1.2GB hard disc
Operating System: RISC OS 3.71

RISC OS 4 was available as a replacement for the Acorn-implemented versions which came fitted as standard.

Our model is the AMC50B - 8MB, 1.2GB hard disc and CD-ROM x8
Reference: 80-AMC50B-1500082

Our system which includes the X10D model 29J44L monitor, keyboard (Acorn part number 0391.400/01) and mouse was very kindly donated by Adrian Besant.

We also have the Acorn A7000+ Welcome Guide AMR copy (Ref: 1402.215 ) and the X10D monitor User's Manual.
