Acorn A7000
The A7000 and A7000+ were Acorn Computers' entry level computers based on the RiscPC 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 RiscPC into a single chip.[1]

History
The A7000 was launched in 1995, featuring a 32 MHz ARM7500 processor.[1] The more advanced A7000+ was launched in 1997, featuring a 48 MHz ARM7500FE processor.[3] When Acorn Computers was broken up in 1998 Castle Technology bought the rights to continue A7000+ production.[5]
