RISC OS history
Arthur - RISC OS 2.0

RISC OS was originally named "Arthur" and designed for the Acorn Archimedes, First publicly released as Arthur 1.20 in 1987[1], for the 2.0 release Arthur was renamed to RISC OS 2.0 in 1989[2], RISC OS 2.01 was released to support the later Acorn Archimedes which used ARM3 instead of the previously used ARM2.

RISC OS 3.0 - 3.71

RISC OS 3.0 was released with the earliest versions of the A5000 in 1991, RISC OS 3.1 was released and built into the A3010, A3020, A4000, A4 and later A5000 models. due to the buggy state of 3.0 RISC OS 3.1 also made replacement ROMs for A5000 and earlier Archimedes machines (this is the last RISC OS version suitable for those machines), there were three veriants released: RISC OS 3.10 (base version), RISC OS 3..1 (Which fixed some serial port issues) and RISC OS 3.19 (which was a German Translation).

RISC OS 3.50 was released with the first Risc PCs (1994), due to the vastly different hardware of the Risc PC (including a ARM6 processor) 3.50 was not made available for the older Acorn machines. RISC OS 3.60 was released in 1995, this version improved hard disk and networking support (TCP/IP, hardware support was imrpoved with support for the ARM7 proccessors (later Risc PCs and the A7000). RISC OS 3.70 released in 1996, the major change was support for the StrongARM proccesor (made available as a upgrade for the Risc PC), 3.71 was a small update released to support the A7000+ (ARM75000FE processor)
