Acorn personal computer
Acorn produced upgrade packs which allowed Risc PC owners to upgrade to the latest specification with a new CPU card and new RISC OS version. Like many RiscPC owners, my Risc PC started out as a Risc PC 600 and was upgraded to a StrongARM CPU and Risc OS 3.70. Since then it has been further upgraded with an APDL Turbo 287MHz StrongARM CPU and RISCOS LtdRISCOS Ltd's Risc OS 6.
This is an almost original Risc PC 600. It is shown running RISC OS 3.50 and has not been upgraded to RISC OS 3.60. If it wasn't for the fact I want a RISC OS 3.50 system I would upgrade it! However the !BootBoot has been upgraded to the Universal !Boot.
