SRP = Set Register Pointer. With this instruction you set the base address of the zero page called "working registers".

There is no DIV instruction, but I have ported a division routine from the z80 to the eZ8!

Edit: Changed some little things and added ckeditor

yay, congradulations!

There is also an atari2600 cartridge reader made by me that uses the eZ8 as well as a homebrew computer.

Are there any devices that use the Z8 Encore! or do you have to build your own? I like the tutorial pages, they look nice. I haven't read through everything but i don't quite get how the General Purpose Register File is different from RAM, and on the third tutorial "If you did not create a new project yet read tutorial 1 again." The "...did not create... yet" bit to me sounds like it should be "...have not created... yet", though maybe we just have a different style of speaking. And what exactly does srp do? What would the difference be between srp #00h and srp #10h? It's a cool little site, though

EDIT: Also, the math link you posted in here doesn't load anything. The one on the site loads fine, though: http://ez8tut.sourceforge.net/index.php?p=reference/math.php
Comparison only has one 's', btw. And woohoo! mult! Is there no div?

Back in 2010, there was a project on Omni with Alberthrocks and Graphmastur, who wanted to build a set of two calcs. One being an eZ8 calc and the other, higher end model, an ARM one. Sadly, it died, but I guess such projects requires too much planning unless you are in vacations during 6 months.

Not to get off topic too much, but I thought one of those projects was an ez80, which is different from the ez8.

The eZ80 is a very nice cpu. There are a lot of peripherals on board. Some people use them to host webpages.

If an Arduino can do it (and it does ), an eZ80 should be able to do it, no problem

Added a page for the devboard schematics I made.

I am also working on a projects page. It will feature projects of mine as well as build instructions.

I noticed the website is still very usable in a text-only browser. I made some tweaks so it's a bit more user-friendly. I moved the menu bar to the bottom of the page.You usually skip trough these links so you can read the text anyways.



Browser is elinks. To get it to look just like this picture you need to enable 256 color mode.
