Acorn BBC model B. The Model B had the same features but had 32 KB RAM (expandable to 64K).
The ‘beeb’ as it quickly became known was fantastic for connecting to external equipment. It featured an anlogue ‘joystick’ port, a digital ‘user’ port, a 1Mhz bus connection, a ‘tube’ connection and a plethora of other connections. So many in fact the the back of the machine ran out of space and they had to create a cut-away bay underneath the machine to accommodate them. But it was due to its connectivity and expandability that I really took to the beeb and started designing peripherals and software.
