The Z80-MBC2 kit I ordered is being assembled. Still a few days until it's shipped, then I should receive it in a week or so.

Can't wait to play with this Z80 homebrew computer.

I finally received the Z80-MBC2 Z80 homebrew computer and connected it via USB serial to my Chromebox (at right in the photo).

So far the Z80 device is not recognized neither under Chrome OS, nor Android, nor Linux. I'm investigating.

It works!

I made chromeOS detect the Z80-MBC2 Z80 computer connected via USB by... re-plugging the board. In the screenshot, see the Z80-MBC2 booting up CP/M 3.0 in a Minicom session under Crostini Linux. More details here:

Time to play with this awesome little gadget. The "Z80 inside" logo alone is worth the product.

In this Minicom terminal emulation session, an Intel 8080 Assembly hello world demo runs under CP/M on a Z80 homebrew computer.

Nothing fancy, but for me it's an incredible personal achievement. I assembled the demo's 8080 source with an assembler I wrote myself. I posted a bit more about the project here:

Playing with the Z80-MBC2 is a fun retrocomputing project. So here are the obligatory vintage cool-retro-term screenshots of this Z80 homebrew computer running CP/M 3.0 and a couple of games.

I've been using the Z80-MBC2 Z80 homebrew computer for over a week, so I posted my early impressions about the device, its value and potential, and the issues I'm facing.

I ported to CP/M my Intell 8080 Assembly demo of a twirling bar animation.

Here is the demo running under CP/M 3.0 on the Z80-MBC2 Z80 homebrew computer. The Minicom session controlling the Z80 board is in the Crostini Linux container of chromeOS on my Chromebox.

8bitnews featured my Z80-MBC2 projects in issue 55. This is so cool, many thanks to the editors Jan and Bastian! is my favorite retrocomputing newsletter.

@amoroso very cool! Do you have any favourite things you like to do on CP/M?


@stevelord Thanks!

I mostly do a couple of things on CP/M. First, I run the Assembly code I write with the development tools I create, e.g. my own Intel 8080 toy assembler. Also, I get to know an operating system I've always been curious about, as back then I never got a chance to own or use CP/M machines.
