- Reverse-engineering the Z-80: the silicon for two interesting gates explained (righto.com)
I’ve been reverse-engineering the Z-80 processor, using images from the Visual 6502 team. One interesting thing about the Z-80’s silicon is it uses complex gates with multiple inputs and multiple levels of logic. It also implements an XOR gate with an unusual pass-transistor circuit. I thought it would be interesting to examine these gates at the silicon level and show how they work.
- Asiago cheese (Wikipedia)
Asiago (UK: /ˌæsiˈɑːɡoʊ, ˌæzi-/ ASS-ee-AH-goh, AZ-, US: /ˌɑːsi-, ˌɑːʒi-, ˌɑːʃi-/ AH-s(h)ee-, AH-zhee-, Italian: [aˈzjaːɡo]) is a cow’s milk cheese, first produced in Asiago in Italy, that can assume different textures according to its aging, from smooth for the fresh Asiago (called Asiago Pressato, which means ‘Pressed Asiago’) to a crumbly texture for the aged cheese (Asiago d’allevo, which means ‘Breeding farm Asiago’). The aged cheese is often grated in salads, soups, pastas, and sauces while the fresh Asiago is sliced to prepare panini or sandwiches; it can also be melted on a variety of dishes and cantaloupe. It is classified as a Swiss-type or Alpine cheese.
