Hi All,
I'm sorry for the severe lack of presence here on the forum, but I've been through a mad busy patch with not only work, but looking for work, then work again, no rest for the wicked! anyway, things are beginning to settle again a little :D phew ( I know, I shouldn't tempt fate saying that though haha )
But anyway, thought I'd let you all know, I may have been gone, but not forgot the prop, missed it like crazy! and to show my appreciation for this little gem of a chip, I'm working together with Coley on a little surprise comeback so to speak!
All will be revealed in a week or two :D

Cheers,
Baggers.

PS, god you guys have been busy whilst I've been gone! shed loads to read and catch up on!

    Does this mean we *might* see you release PropGFX in some form or fashion?

    Welcome back!

    I missed seeing great demos from you.

    @Jeff, PropGFX is a different matter, I will persuade Jim to release the code in some form or another.
    It's been a long time coming but it will come.

    @Baggers, enough teasing now, lets just get on with it! :cool:

    @Baggers,
    Great to hear that things are settling down for you.
    Looking forward to what you might have in the works. Here's hoping it is HOH ;) (Ok, so maybe that is just wishful thinking on my part).

    Thanks Bill and trodoss, this next demo will be a good one.
    Not HOH yet trodoss, but I will get back to that after this!

    Jim.

    Welcome home, Baggers. We're glad to have you back with the whole family for some home-cooked meals and some good Prop discussion. Since you've come this far you might as well get a ticket all the way to UPEW. I'd be glad to have Uncle Tom pick you up at the airport, or I'll do it myself.

    I think you are returning in time for some excitement, too. Your sabbatical for work was well-timed. We're making some positive progress towards Propeller 2 and Parallax is going through a bit transformation for the Propeller - more on that to follow.

    Hi Ken, thanks for the warm welcome back :D As for UPEW, if I could afford the £6k to fly there I would, I've been wanting to come see you guys for a few years now, but can't justify the price tag, even when my brother-in-law was in Cali, we priced up tickets again, and that was just the flight only! Otherwise I'd jump at the chance to come to UPEW! and see it live! plus obviously the pilgrimage to Parallax :D

    As for the timing of my return, seems pretty good! haha, interesting times ahead! look forward on the "more on that to follow"!

    Head over Heels, I meant to finish that off after Eindhoven, but so many many interruptions got in the way.
    I may release it after this as is, so people can make their own HOH clones.
    or just use LOTS of sprites :)

    Thanks for the explanation. I'm not much of a gamer myself and hadn't heard of it but the pictures I found in a Google search look interesting!

    I'm more interested in the Hybrid X3 board!

    I need to find my source files for eagle and then I'll post them.
    If enough people are interested I can get some PCB's manufactured, if I remember I re-did the layout making it a lot smaller..... was two years ago though lol

    If you revive the Hybrid X3 I'll take a few PCBs. Looks like it's all through-hole so it should be pretty easy to assemble. Any chance any of the parts you used are no longer available?

    Well I can always revisit the design if enough are interested so I wouldn't think there would be much of a problem, all of it was sourced from Digikey.

    Hi guys,
    Thought I'd give you an update, on what I've been working on.
    I was looking at how everyone has been trying to increase the 8bit resolutions for prop, and all solutions have been trying with either SRAM or SDRAM.
    And decided there needs to be another way, as filling the vram seems to be an issue that people are having.
    So wanted to try and come up with a solution.
    My thinking behind this method is the fact that the Prop's main power, is the fact it has 8 cogs, and all can access hub-ram.
    So I started wondering if two props could do it.
    The answer, well yes, they can!
    But there are a few issues along the way, yes, they are deterministic, and both running off the same clock, so should be perfectly in sync, but no.
    the Bootup is internal RC timing, so not as stable as I'd like it to be.
    So I'm close, and I've got a few ideas for re-syncing once they're both up and running. the issue is the hub-ram round robin needs re-syncing.
    Anyway, here's a quick demo of where it's at.
