CP/M and the ZX UNO

Has anyone been able to load the CP/M OS on the :zxuno: ZX UNO?

I know the Spectrum +3 had CPM Plus, I have a copy but I don't know of a method of loading DSK files into the UNO.

Or is there a CP/M compatible core available?

Sorry my post is in English, I do not speak Spanish and the Google Translator is not always understandable.

Thanks

:gracias!: :zxuno: :chocala!:

Hi THX1138:

Yes, there is a Quest's CP/M machine core. Look at this.

You will need a disk image with CP/M 2.2. Download it from this page.

NOTE: The core isn't 100% OK. There are some display problems in applications like WordStar 3.30, but the machine is faster than light :)

Brilliant, I'll look into this to and find out how to load the core onto my UNO!

Do you know if it is an actual display problem?

Most CP/M display issues are terminal config related, I recall having a problem with that disk image by Grant Searle, such as WordStar 3 display problems when I was working on my Arduino CP/M computer project. But WordStar 4 and some other software from another source worked fine.

Thank you! ☺☺

What about the Spectrum +3 version of CP/M? Wouldn't it be possible lo load it on the ZX-UNO default core?

@desUBIKado: Thanks as always... you always do very interesting experiments with the ZX-UNO, man! :D

I have been reading that thread on the va-de-retro forum and there's a LOT of info there. I seem to understand that there is still some file writting problems with CP/M in the ZX-Spectrum core, right?

@Vanfanel: Yes, the CP/M 3.0 works very well in ZX-Uno, but disk write operations don´t work. otivax ,the author of this marvel, could not fix, and this was six month ago. I will try write him, perhaps he could say us something more.

@desUBIKado: that would be great, because saving progress in CP/M text adventure games is important :D

In fact we'd need a PDP-10 core to play Adventure as Crowther did.
