    @Jim

    Now I am confused.

    First you said "Yes, but in private a couple have admitted to actually receiving them."

    Then you said "two developers you are well familiar with either have them or at least were offered the boards."

    Is this 2 different instances? One group that did receive boards and another group that either do or do not have boards?

    No...more specific. Brainfarts are spontaneous, this crap took planning...bad planning.

    More like a "brainshit" than a "brainfart". ;-)

    Nah, started as a brainfart and then noone had the brains/guts to stop it from being implemented.

    We refer to that as a "shart". Starts out as a fart, but then something more discusting occurs.

    So maybe a "brainshart"?

    I notice Acube doesn't seem too interested in discussing this board.
    I thought they were to be involved, but outside of firmware I don't see it.

    Someone else recently contacted me about the idea of a T10XX based board, but its really too big a project to take on without an experienced partner (i.e. - Varisys, Acube, Genesi, etc.). This idea never gained traction when I was pushing it, so I'm wary of re-involving myself with it.

    Right now, I'm rooting for Roberto Innocenti's project. At least he had the sense to team up with a profession design company.

    It hasn't.

    There is no T2080 laptop board design yet, just schematics, as the start of the board design phase requires the final chassis to be decided for first, which hasn't happened yet.

    Not necessarily backpedaling, I was told two were received.
    I just have this bad habit (probably from my business training) of always adding qualifiers.

    Yes, that does make a difference, doesn't it?

    Since the Soc is only part of the board pricing equation, and a T2080 is only about $150 more than a P1022...

    As to 'only' having the schematics, hey, I'm actually surprised it got that far. And as to chassis, that does complicate board layout, but a specific chassis was discussed awhile ago.

    If I could have dragged Bill Buck into this, sourcing a chasis might be easier. After all, he used to make laptops and even had prototypes of a low cost model made by a Mexican firm ATTO. If new C64 and Amiga cases can be made, a laptop case is only a bit more complicated.

    Current pricing at distributors looks different than years ago. Lowest single-quantity prices I can find now are about 100 USD for 1.2 GHz P1022 and about 200 USD for 1.8 GHz T2080. Seems P1022 price has about doubled over the years, but I believe A-Eon stocked up with P1022 chips when it was still cheap.

    Yes, it's just there's no work on board design started yet that could be adapted for anything.

    > a specific chassis was discussed awhile ago.

    This may be, but a week ago there was still no decision arrived at, as reported in the linked status update.

    Yes, but the point is we do more than discuss, we get scheisse done.

    The design, when laid out, should lend itself to reworking as a mini itx board.

    One thing I've been thinking about is would you keep the MXM connector, or and a PCI-E slot?
    The former would make everything much more compact, but the later allows for more powerful graphics (then again, how much power does MorphOS need).

    Periodically a vendor for Cadence Allegro contacts me to see if I want to upgrade my design software.
    If the layouts get done (and Acube is ready to strt them), I may just have to blow the $1500.

    If I had a functional layout, I have contacts that could build the prototypes.

    After all, my company used to build hardware in the '80s and '90s.
    Its just a LOT more complicated now.

    Yes, A-Eon could commission ACube to do this for a new T2080-based product after Tabor.

    I'd go for a PCIe slot.

    My inclination too, but think of how small an MXM based system could be.
    It could make a Mac Mini look large.

    Addendum:

    > I believe A-Eon stocked up with P1022 chips when it was still cheap.

    Confirmed by Trevor Dickinson:

    "We pre-paid for 1,000 P1022 CPUs [...] in preparation for the first commercial production of motherboards which we anticipated would take place in late 2015/early 2016. [...] We have all the CPUs in-hand [...]. [...] we ordered and pre-paid for all the long lead time items including 1000 Freescale P1022 CPUs so we would have the key components available once we started the full manufacturing run."

    It isn't cursed, it's just far too small and its ownership far too fragmented and unsure to make any return on any money put into it.

    Trevor should know this by now, but he keeps battering his face off a brick wall nonetheless.
