The A7000 and A7000+ were Acorn Computers' entry level computers based on the Risc PC architecture. Launched in 1995,[1] they replaced some of the models of the Acorn Archimedes range.[4] After the breakup of Acorn Computers in 1998, Castle Technology bought the rights to continue production of the A7000+.[5] 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.[1]
