Provides RISC OS based computers with BBC Microcomputer I/O.

The Single Width I/O Expansion Card, for a RISC OS based computer with an expansion backplane and RISC OS 3.1 or later, provides the 1MHz Bus, User Port and Analogue to Digital Converter interfaces of the original BBC Microcomputer.

Unlike the Acorn Double Width I/O Expansion Card (which cannot be fitted in the A7000, Risc PC and IYONIX computers), the single width card has a 25 pin Male D-type connector instead of a 20 way ribbon cable connector for the User Port.

To enable existing peripherals to be used an adapter cable is available to convert from the 25 pin Male D-type connector to a 20 way ribbon cable connector. Note that the single width card cannot have a Musical Instruments Digital Interface (MIDI) upgrade fitted.

The Single Width I/O Expansion Card ROM contains the Intelligent Interfaces version of the I/O_Podule Module for Single and Double Width I/O Expansion Cards.

The Single Width I/O Expansion Card is supplied with a comprehensive User Guide which includes example programs in BASIC and Assembler.

Download the Single Width I/O Interface Expansion Card User Guide (pdf format) to learn how the software is used.

Download the II74 26 Bit Version 2.03 of the I/O_Podule Module and associated software.

Download the IM74 26/32 Bit Neutral (IYONIX pc compatible) Version 3.00 of the I/O_Podule Module and associated software.
