Just a bunch of opinions
Apr 26, 2017

This week, I’ll report about some progress on the next EZ-Retro “v2” PCB and build (which isn’t quite right yet, unfortunately).

But first, a topic which has been keeping me busy lately… typing and the keyboard:

No, not the above Simplified Chinese one:

As the title of this post says, these are all just very personal opinions of course, so please take with a grain of salt and brush it off as random rants when you don’t agree with some, or even any, of this…

Circular motions
Apr 19, 2017

Just back from a few days in Paris, visiting friends (a bit south of Paris, actually), but we did manage to squeeze in a stroll in the Jardin du Luxembourg - with memories of a (brief) childhood there, bringing my sailboat to the pond, always hoping that it wouldn’t get trapped under the fountain…

Once back, I fell into all the procrastination traps there are - yak shaving, bikeshedding, and other rabbit holes. Dealing with some updates, failing laptops, and “researching” (ahem) all sorts of “interesting” (cough) topics, from Qubes OS to Awesome WM.

So nothing useful to write about this week.

Oh well, c’est la vie…

EZ-Retro Z80 - part 2
Apr 12, 2017

Getting CP/M working on this two-chips-plus-a-blue-pill setup took more time than I thought, especially on the software side.

This week, I’ll turn Forth into a peek-and-poke monitor for the eZ80, describe how to bootstrap the initial code, build a minimal BIOS for CP/M, add a µSD card socket with SPI request bus, and finish off with a FAT-file mapped jukebox style floppy disk setup.

Let’s get started, this will be a long episode!

As always, these articles appear spread out over separate days of the week, to give me some time to prepare and test it all, but also to show that it’s all part of a “fun” journey!

Will it end here? Probably not. I’m thinking of making a PCB board for this. It’s been a delightful mix of a variety of technologies, new and old, and the retro aspect made it really satisfying once it all came together.
