A little update

There is a little update, now that I’ve receieved one of the Most Amazing frontpanels created by Paul – and holy cow does it look good! He made one for himself compleet with wooden sides etc, and oh my…. I’m working on the Teensy version as well and mostly actually on the software, which is […]

The next phase

/

So now that we have succesfully cloned the Zyklus with that learned a great deal on how it all works from a hardware perspective, it’s time to get deep with the code and try a new hardware platform. Obviously the Z80 is limited, which is why the code included some very handy bank switching to […]

Getting the OS builds working

The original Zyklus code was written in Z80 Assmebly, using a Macro assembler from 1985. Thanks to the current popularity of retro computing and the vast resources of the internet, I managed to obtain a copy of the assembler (though not the linker, although I’m fairly certain I have one from an earlier release that […]

Running the Zyklus on the MCLZ8

After having new MCLZ8 boards created, this time with the components pre-populated (and thanks Paul for guiding me through the ordering process on that), I now have a working MCLZ8 emulator running. The emulator supports various modes, two of whcih are interesting for us: Mode 0, which means the emulator runs without acceleration, using external […]

PaulMC

I want to introduce our user PaulMC a bit. This gentleman has been responsible for a lot of the succeses we’ve had. He took the schematics and created new PCB layouts and basically nailed them in the first try. Then he surprised us with a completely redesigned modern power supply, suitable as a drop-in replacement. […]

Trying Z80 Emulator

/

This gentleman (https://microcorelabs.wordpress.com/) has created a Z80 Emulator, based on a Teensy 4.1 module. It is supposed to be a drop-in replacement for the cpu, with which we can use its features to easilly develop new features for the Zyklus. Using this emulator would negate the need to burn new EPROMS, as we can simply […]

Working the software

I’m trying to think of ways to deal with the software. My thoughts for now are to create a hardware abstraction layer with API’s that the software can interact with. By decoupling the logic from the hardware, it should theoretically be easier to develop new functions. And to simulate these. Not sure yet how I’m […]

Long overdue update

/

It’s been a while – I’ve been a bit busy. But here we go. A new Zyklus is born. Actually, quite a while ago, User PaulMc and myself managed to finsih building the first version of the mainboard. While there were one or two little bugs, it ended up working quite nicely! So with that, […]
