1) I'm genuinely interested in that project.
2) It provides me with some motivation.
3) Who doesn't enjoy a race? ... to market ... ? :-)
4) Who are we talking about again? :-p

How to generate disinterest in your project :

Don't post anything for months and don't ever reply to questions or keep previously interested parties up to date.

A bit sad really. I actually genuinely thought they'd have it for sale before I got anything running. I guess that was fairly naive on my part.

Speaking of which, I should hurry up and finish setting up this box so I can write some code!

Wow, that's sure to :

A) put off people that want a serious reliable solution
B) attract people with existing hardware that don't mind hacks
C) as a consequence of B make them more cash

Can't say I'm impressed, more disappointed actually. Oh well, all the more reason for the FreeEMS effort!

that's cool. The SD card slot is nice. Besides, then you can get bluetooth and GPS and all that for it. Kinda sparse on actual hardware, hopefully they aren't sticking with the V3PCB, that thing is half the problem with the MS-II, the other two halves being the software and the MS-II daughter card.

edit: 4 holes along the back for power transistors? USB with no support chips?

I don't see any vias for a TO220 package, so I doubt there's an option for power transistors there. They haven't left enough room for SMT'ing a TO220 either. The expansion vias don't allow for enough space. I suspect those 4 holes are purely mechanical. I don't know why they choose 5 instead of 3 of them.

Those five holes are apparently aligned to match holes on V3 / V3.57 boards. Page 10 of http://www.diyautotune.com/events/megam ... ms3-us.ppt presentation shows how traces are routed on PCB.

Ok, so, I figured out what it was that bugs me about this... Remember how we all somewhat dislike (heh) the MS-II for having all this legacy stuff in it? You know, assembly code, etc? So, the 'all new' MS-III, while having an IO board (ooo - original!), and the main board, with injectors 1, 2 out of 8 or 10 or whatever..., leaves the terrible power handling left over, some fraction of the old drives - in short, just like the MS-IIx software had bits and pieces piled on in hacks to make it do more than it did, the MS-III has this in hardware. I'm really concerned. On paper it does all it should (slightly different processor? What's the difference except a few more MHz?), but I think in reality it's going to be a pain.

I'm not sure I get this "angle clock", it could update the angle clock every rotation or every tooth or some such, in which case what's it buying you, and if it doesn't, it'll be way wrong. About the only thing it could do is sweep the freqency of the chip to match 0.1* of rotation (ha)...


I dunno. Its nice to see some progress, and it has many things I'd like to see on a computer (onboard SD, USB, lots of IO) but I think it's going to retain only the worst parts of the old design... hence making it so much less than it should be.

Anyway, just curious what you all think... Does anyone have any idea what the code looks like?
