At a time when powerful processors are so cheap and much of their functionality left unused in a typical application, it’s delightful to look back to hobbyist electronics projects from forty years ago, and admire the optimised design and the skill of those who created them. MOSTAP is a digital version follow-up to Project #5, The TAP.
In the second issue of Elektor magazine in English, February 1975, MOSTAP appeared as an improved — digital vs analogue — version of The TAP. We've re-created it for the enjoyment of those who may appreciate the elegance of the design today.
This design, as always, is open source hardware; it's available on our GitHub repository. For more detailed information visit this page.
Note: before you do anything, note which side the components are mounted. Look for the symbols described here for an indication.
