The GaAs Field effect transistor and the GaAs monolithic ic were invented and developed at Caswell, but what is probably less well known is that scientists on the site were working on silicon integrated circuit(ic) technology almost 18 months before Jack Kilby demonstrated the first working ic at Texas Instruments in Dallas.
For instance, in order to build the device the group from the University of Nottingham used 50 alternating layers (each just a few atoms thick) of two chemical compounds known as Aluminium arsenide and Gallium Arsenide.
The MTA-2 was an attempt to correct these problems while maintaining essentially the same processor architecture respun in one silicon ASIC, down from some 26 gallium arsenide ASICs in the original MTA; and while advancing the network design from a 4-D torus topology to a more scalable Cayley graph topology.
