As a way of offering continuity with the BBC Micro and the user port, 1 MHz bus port and analogue port that were provided by the earlier range of machines, Acorn announced an I/O podule at the launch of the Archimedes, this being fitted with the 6522 VIA featured in the BBC range, with the possibility of upgrading the podule to provide a MIDI port. A ROM podule was also announced with the anticipation that users upgrading from the earlier machines would choose to fit their application and language ROMs in their new machine, these running under the 6502 emulator provided with the operating system.
