What is KILOZED?

The name KILOZED is rooted in the term of endearment "Zeddy" for the ZX81, combined with "KILO" to signify the supercharged nature of this reimagining.

KILOZED is a passion project of two brothers that joined forces to build a "Zeddy" the way it could have been without Sir Clive Sinclair's budgetary limitations.

KILOZED combines several community-created open-source mods with a custom mechanical keyboard that is true to the original membrane keyboard's legend and layout.

Finally, KILOZED is all housed in a custom 3D printable case that pays homage to the original design by Rick Dickinson.
