We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Acorn Large 32016 2nd Processor

Large version of the Acorn 32016 2nd Processor board, because of the number of memory chips (8*16).

This is the Acorn National Semiconductor 32016 2nd processor, the "Large" refers to the memory size which is 4 MB. The card almost certainly comes from an Acorn Cambridge Workstation, as it would not fit into the standard Acorn "cheese wedge" box.

The CPU is in the top right hand corner with an empty socket for a floating point co-processor next to it. The processor and other gold labelled chips are missing their heat sinks. The socket with the Ferranti ULA next to it is the Tube connector to connect to a BBC Micro. Most of the rest of the board is taken up with memory chips.

Date : Unknown

Manufacturer : Acorn Computers Ltd

This exhibit has a reference ID of CH33917. Please quote this reference ID in any communication with the Centre for Computing History.
