[sdiy] Identification of an unknown MIDI CV interface

The ULAs were developed at one of Ferranti's sites around Manchester, with early uses in the military side of the business.  But Clive was an early adopter of custom silicon and had already had customised versions of ICs from TI and ITT made, so using the ULA was a natural progression from there.  One wonders what sort of synthesiser he might have produced had he been more interested in creating music.

Anyway I did a quick search of Ferranti Dundee and this very niche advert came up which made me smile - Dundee sits on a river with two bridges going across it, recreated here with sockets :-)

Howdy Neighbour!

Ferranti had a big factory not so terribly far from Timex, where they made the ZX81 and ZX Spectrum - which used Ferranti ULAs! I wonder if that was a contributing factor in the decision to use them.

I'm guessing you're in roughly the same age demographic as me, and grew up with a ZX Spectrum along with everyone else at school ;-)
