SpaceFlights.us: ”Zero overhead” Z80 computer focuses on performance

There's something quite satisfying about building your own computer. Nowadays, constructing your own desktop PC is relatively easy, so if you really want to get your hands dirty, you have to take a step back in time and give some vintage hardware a spin.

[YT2095] has spent a good portion of the last two months building a computer based on the classic Z80 CPU. His machine, called ”Z Eighty Development” or ”ZED” for short is an amazing build, and most definitely a labor of love. He has put an estimated 700+ hours into this machine and it's a beaut! When closed, the machine is pretty unassuming, but once he folds down the keypad, you can see that all of his time has been put to good use.

Most of the board's components are connected together via wire wrap, including the large 48k memory card he built, as you can see from the link above. The wide array of add on cards all work together to accomplish his goal of ”zero overhead” - freeing up the Z80 from having to do any unnecessary processing, such as I/O, etc.

It's quite an impressive build, and ranks up there with some of the best Z80 based computers we have seen through the years.
