Sorry, I mistyped - it is the SZ variant with color LCD and 66MHz CPU that is being considered. >But do you know more about the USB interface?

(I know >the sotware problem of drivers, it is not the question). The USB interface is not a USB 'HOST' but rather a USB endpoint. I.e, a SZ328 system with propper software support becomes a USB device, rather than a host (or, to use simpler terms, a controller). As such, this port will not be able to accept other USB devices directly, although there appears to be a way to do this using some sort of a USB bridge device, something which is commonly used in USB to USB networking cables, for instance. Specs on this are very difficult to find. I have only seen it referred to in a completely unrelated document (for a Cirrus - Crystal MP3 player chip), where this approach is used to connect USB mass memory devices. >And: is it available in reasonnable quantities, ie about 50 units? This is what I am trying to find out at the moment. There is a bit of a mechanical problem with it as it uses a BGA case, which requires special soldering equipment, but I think this could be circumvented with a different approach to PCB design. _______________________________________________ QL-Users Mailing List
