Hi all,

We've released MikeOS 3.0 with a major code cleanup, better documentation, file manager improvements and new system calls. The experimental DOS and mouse support features have been removed and will continue development in the TomOS project (currently being worked on). The full changelog is detailed in this mailing list post.

As MikeOS is designed as a learning tool, we've expanded the documentation into three parts:

• User Handbook -- Running MikeOS and the included programs
• App Developer Handbook -- Writing new software (with a full API guide)
• System Developer Handbook -- Building and modifying MikeOS

We've tried to make the documentation as clear and concise as possible, so if anyone spots any flaws, please let us know!

And if anyone wants to help out with new OS features or writing MikeOS programs, join the mailing list. Information on that and downloads for the new release are on the website:

Cheers!

Nifty, good work Mike! Love the new handbook schemes, but I think the appdev one should have been blue to go with the whole RGB thing.

Wow, I just noticed, TBOS doesn't even have a readme file. Crapcrapcrap.

That was the original plan -- but then links didn't really stand out, so I went with a charming shade of orange

Well the orange looks like it's between green and red, so it could be an indication of the difficulty level

very cool os,
keep the good work comming.

Congrat's on the realease. I will try it out when i can. I've been very busy on Patricknet development. keep up the good effort for the learning tool.

Hi all,

Hi,

MikeOS 3.2 has been released with these changes:

• New system calls to convert a signed integer to a string, and reverse a string
• FAT12 calls now no longer need FAT12-formatted filenames (they do the conversion internally)
• Serial port is not initialised by the kernel, but by external programs
• The OpenBSD build script has been updated

This mailing list post has all the changes. Thanks to Tslil Clingman and Takayoshi Sasano for their work!

Cheers,
Mike

I haven't followed MikeOS too closely (lack of time), so this may be part of its design goals, but aren't that things that usually go into a (shared) library instead of the OS?

Hi Jal,

Yes, in a proper OS with shared libraries you're totally right. However, MikeOS is largely striving for simplicity and fewer 'moving parts', so the kernel functions as a shell, executable loader, and library of common routines all in one place.

A string-reversing function is pretty trivial on the grand scheme of things, but the MikeOS kernel (with over 60 function calls for screen handling, strings, math etc.) is still only 7K, so I don't mind dropping in the odd tiny gimmick

Hi all,

MikeOS 3.3 is now available. Changes in this release:

• New full-screen text editor (screenshot)
• Command line can now 'cat' text files
• Music keyboard interface updated

...plus changes to the API and small updates as listed on the mailing list.

Cheers,
Mike

Yikes, I need to release 1.0.0 soon or be stuck in the dark ages forever!

Gratz on the release, Mike. Can't wait to see 3.4
