The IBM System/370 Model 145, 1970. The System/370 Model 145 was the first general-purpose business computer to use monolithic circuits in all memory and logic functions, and used semiconductor technology rather than magnetic cores.

Donut Math

Program in C code, shaped like a donut, renders a 3D donut shape in ASCII, originally put together in 2006 by Andy Sloane:

At its core, it’s a framebuffer and a Z-buffer into which I render pixels. Since it’s just rendering relatively low-resolution ASCII art, I massively cheat. All it does is plot pixels along the surface of the torus at fixed-angle increments, and does it densely enough that the final result looks solid. The “pixels” it plots are ASCII characters corresponding to the illumination value of the surface at each point: .,-~:;=!*#$@ from dimmest to brightest. No raytracing required.

I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible.
