If it ever gets as popular and as stable as the DivIDE, we might see an internal version one day. :)

    Who said that ? Dave has had a working prototype of his USB interface for ZX for months (or is it years ?)

    Heh heh. Not impossible, just not necessarily the best technology choice :)

    The last sentence from that webpage sums it up:
    "It is a BIG challenge programing over USB."

    :D Lots of CPU and lots of software.

    I'm aware of Dave Mill's work, but according to him the interface wouldn't work and has to be re-designed. It's one of the projects on his to-do list.

    Hmm, I remember him testing loading full 48k of bytes via USB and it worked, he was working on loading a full snapshot (together with all the registers, etc.) at the time... so I am pretty sure the thing worked and just needed software support. I am not sure how far he got with it though.

    And Dave's USB was a slave unit only, mine is a HOST, those found on pc's.
    Slave unit cannot access USB mass memory, USB mass memory is a slave
    unit and connects to a HOST unit.

    Not lot of Z80 CPU if I would say, HOST USB chip has dual CPU power to
    handle the USB bus. ;)

    When considering a Speccy project, it boiled down to Ethernet or one of those USB host chips designed for microcontrollers (and ideal for 8 bit stuff). I decided that ethernet would be a lot more fun. USB looked like a bit of a pain in the arse for anything other than mass storage or keyboards.

    thats emence. i do a far bit of work on pc with nt on them, its a real pain in the butt as usb don't work. Everyone who works on computers/control systems has to love the irony of this. .............................. sweet.

    I still think the spectrum should some how be using a zip drive. They are cheap, the media is big enough for the spectrum and you can record to it.
