it looks like you have plenty of people working on this already, but i would gladly help with anything you need nonetheless. i has an 83+ that's expendable, and money/experience to piece together my own prototype(if someone gives me specs, that is)

I'm still not so sure it would be such an easy task to just port KOS to a new hardware platform. I am almost certain that the memory layout will be massively different (24-bit addresses, no page swapping) and all the hardware you are familiar with on the TI will not be the same at all. I think it would work much better to start from scratch with the OS on our new system. Have you looked at the eZ80 documentation? I recommend giving that a read: http://www.zilog.com/docs/um0077.pdf

Again I agree with you, this thing is NEW and so should everything we make for it be. Now KOS isn't 'old' strictly spoken but indeed you can't port it over with great ease, not to discourage you! I greatly support KOS and I would love to see it on the OTeZ80 but once again I suggest taking KOS for the TI-8x as a reference, not as a template, or worse.

I think SirCmpwn and some other developers can just write a new OS for the new calc. If the base is vastly different, then we should just write a new one, but use KnightOS as reference.

Exactly! I completely agree. Don't underestimate the effort of writing a OS though! (I don't think you do but your text can be interpreted like that)

Oh no, it's VERY VERY VERY (continues infinitely) hard to design an OS. Remember people, don't design an OS, especially for x86 systems. :P

Also, I would like if the focus was still on the 83+ version of KOS. I would hate if KOS made it to this new calc at the expense of 83+ users who were waiting for a new 3rd party OS. Also he got a contest entry to finish and the contest ends in 1 month.

i would love to test for you.

note:
1.i will use an emulator if there is a chance that it will completely destroy my calc.
2. As long as there is no chance of bricking, i will be glad to use my 84+ SE if it is compatible.

I was thinking of starting from scratch and reusing code where applicable.  I never thought that we would port it, especially not with a different kind of screen and all sorts of other factors.  I was going to provide the same KOS experience that people would get on a TI-83+, but optimized and improved for the OTeZ80.

Count me in as well - I'd be happy to do beta testing (when I have the time, that is :P).

I don't know how much of a help I would be with actual coding - I'm still kind of, well, beginner-ish at z80.  I am certainly willing to help, though.

For the record, the help I get from coders will probably not be on the kernel.  Me and Eeems are plenty.  Most of the help will come later on, with writing math apps and the like.

I'm not accusing anyone, merely pointing out how I would organize it.  Too many people on a kernel can be bad.

good point.  I can stick to beta testing right now.  We'll see what I do in the future.
