Building the ReZyklus - Vangelis' Zyklus MPS1 Clone



This one is in via Jeroen of https://zyklus-mps.com/

"A while ago a group of enthausiasts set out to create a clone of the Zyklus MPS-1 that was made famous by Vangelis for its use on Direct (this was also the inspiration for the actual 'Direct' system he used until ca 1994). The original creators of this machine, Pete Kellock and Bill Marshall graciously allowed us to use the schematics and software to create this clone and have given us their permission to set it free for everyone who wants to make their own. So here goes:

In this GIT repo is everything you need to create your own machine. You will have to source your own parts, but there is a list for that. The parts are basic components, nothing custom, but some items may become slightly rare (like small EPROMs).

Its basically just a Z80 based computer.
There are also files to have the circuit boards and panels created (we used jlcpcb for that), and some 3d printing files for various panel work. A lot of the buttons etc you can get cheaply from Aliexpress and the like. Bin files for the EPROMs are also avialable. I've been also given permission to open source the actual source code, and I will do that too, at some point, but I'm still working on a few small issues before I can do that.

There is a discord server you can join where you can chat with other builders.

The clone as we made it, is a dedicated to the memory of Vangelis and it's noted as such on the main circuit board."

See this previous post for a Demo tape on the original Zyklus. See the Zyklus label at the bottom of this post for additional posts including a documentary with Vangelis.
