The 8-bit home computers of yore that we all know and love, without exception as far as we are aware, had an off the shelf microprocessor at heart. In 1983 …read more Continue reading The Computer We All Wish We’d Had In The 8-Bit Era
Through all the generations of computing devices from the era of the teleprinter to the present day, there’s one interface that’s remained universal. Even though its usefulness as an everyday …read more Continue reading A Journey Into Unexpected Serial Ports
When thinking of the first PCs, most of us might imagine something like the Apple I or the TRS-80. But even before that, there were a set of computers that …read more Continue reading Rebuilding The First Digital Personal Computer
Although marketing folk and laypeople may credit [Steve Jobs] as the man behind the success of Apple, those in the tech world know the real truth that without [Steve Wozniak] …read more Continue reading Single-Stepping the 6502 Processor
We’ve all heard of the dangers of static electricity when dealing with electronics, and we all take the proper precautions when working with static-sensitive components — don’t we? But as …read more Continue reading The Other Kind Of Static Hazard to Your Logic Circuits
We’re no stranger to homemade CPUs on these pages, but we think that [Jiri Stepanovsky]’s 16-bit serial CPU might be a little special. Why? It has an astonishingly low chip …read more Continue reading Only 8 Chips Make A CPU
MikroLeo is a discrete TTL logic-based microcomputer intended for educational purposes created by [Edson Junior Acordi], an Electronics Professor at the Brazilian Federal Institute of Paraná, Brazil. The 4-bit CPU …read more Continue reading MikroLeo, A 4-Bit Retro Learning Platform
These pages have not been exactly devoid of home-built computers, with those constructed on solderless breadboard less frequent, but still not rarities. But what is more of a rarity is …read more Continue reading A Well Documented BreadBoard Computer Shows Dedication
Building a CPU out of logic gates is a great way to learn about the inner workings of microprocessors, and we’ve seen several impressive projects in this area. [c0pperdragon] set …read more Continue reading BreadBin is an 8-bit TTL CPU on a Breadboard, in a Bread Bin
We’re used to computers with display screens, yet how many of us have created the circuitry to drive one directly? Sure, we’ve coded up an SPI display driver on a …read more Continue reading Creating Video From a ROM
