The Zx Spectrum Ula- How To Design A Microcomputer -zx Design Retro Computer- (Top 20 PREMIUM)

However, the first ULA had a darker secret. It ran hot. In the rush to pack so much logic into the chip, the power consumption was higher than anticipated. The prototype machines, encased in the sleek black plastic designed by Rick Dickinson, would overheat after an hour of use.

Embarking on a retro computer design project can be a rewarding and challenging experience. With dedication and persistence, you can create your own ULA-based microcomputer and join the ranks of legendary computer designers like Rick Dickinson and John L. H. ( Sinclair Research Ltd.). However, the first ULA had a darker secret

The task fell to engineer . While Clive Sinclair obsessed over the sleek case design and the price point, Altwasser had to figure out how to cram the complexity of a color computer into a single piece of silicon. He chose an Uncommitted Logic Array from Ferranti—a type of semi-custom chip that was essentially a "blank slate" of logic gates waiting to be wired together.
