I'd love to see a deep dive into the 303 CPU and their replicas like https://www.sonic-potions.com/re303 and https://socialentropy.com/pages/product_qs303
sonic potions has an analysis of the cpu timings here https://sonic-potions.com/Documentation/Analysis_of_the_D650...
Theres also some nice articles about the diode ladder filter in the 303, similar to the one in the vcs3 https://www.timstinchcombe.co.uk/index.php?pge=diode2
