How do computers calculate complicated trig functions such as tangent? I took a look at Intel's 8087 floating-point chip under the microscope to find out. The chip combines two techniques to evaluate the tan function quickly and accurately: polynomials and an algorithm called CORDIC...

A die photo of the 8087 chip under a microscope shows complex patterns from its transistors and wiring. The middle of the chip holds the microcode ROM, while the bottom half of the chip is the datapath that performs calculations. Zooming in on the datapath shows various functional blocks, which appear as rectangles with different textures. Important functional blocks are labeled: exponent ROM, constant ROM, shifter, adder, registers, and so forth.

it's the 70th anniversary of the IBM 305 RAMAC, the world's first hard drive! in celebration, here is a picture of a prototype RAMAC magnetic head.

nickel-sized round magnetic head with a tiny rectangular pole piece in the middle. it is mounted in a two-axis gimbal so it can rotate to align perfectly with the surface of the hard disk. on the back is a connection for an air line.

The IBM 5150 had a cassette tape interface. It was used for almost no commercial software whatsoever. The only known title that exists on cassette is IBM's own diagnostics. MartyPC will eventually emulate it - with this fun pixel-art visualization. #retrocomputing #emulation #pixelart

An absolutely massive update to martypc.net Now you can choose to emulate four different systems, from the IBM 5150 to the Tandy 1000. On the PC you can now can choose from a number of video cards all the way up to VGA. And oh yeah, Adlib (OPL2) syntheis. #retrocomputing #emulation #martypc
