I use a BlackBerry provided by the network operator I subscribe to in Hong Kong. It works fine, but I have big fingers and I miss using a proper-sized keyboard, such as that I had with my old Psion organiser. My service provider refuses to give me one, but does such a keyboard exist for the BlackBerry? Ron, Lantau Island DQ: Many websites specialise in keeping old personal digital assistants, such as the Psion and Apple's Newton MessagePad (right), in working condition. It seems nostalgia is running high in the technology market. I have found a number of compatible keyboards, both wireless and wired, that you can use with the BlackBerry or other handheld organiser/communications devices. Visit the usual places to find this sort of peripheral equipment in Hong Kong, such as the Wan Chai Computer Centre, above the Wan Chai MTR station. Alternatively, look at www.eaccess-estore.com . There you can find a thin and flexible keyboard for the BlackBerry, which you can hook up using the mini-universal serial bus (USB) connector. This handy gadget features many BlackBerry menu shortcut keys. Another option from the same site is a compact and lightweight folding keyboard, which can be linked via wireless Bluetooth connection to a BlackBerry, meaning no cables. My father owns an old Apple Newton and he still goes on about what a great device it is. Although we all laugh at him about it, I wanted to surprise him by helping him connect it to his new computer, which runs Mac OS X. Is this possible? Name and address supplied DQ: The Newton MessagePad was an early line of personal digital assistant (PDA) developed and marketed by Apple from 1993 to 1998. Although the device's official name is MessagePad most people refer to the PDA using the name of its operating system, the Newton OS. According to those who love the device, it was way ahead of its time. For your project you will need two things: a USB-to-serial connector and the relevant software. You can try to find the USB twin serial adapter at www.keyspan.com and the NewTen software at stevenf. com/software/newten. This Newton solution ought to keep your father happy for some time. Interestingly enough, the NewTen software is based on work done by Richard Li (no, not that one) at the Newton Users Group at the University of Hong Kong. This means we have some serious early technology adopters who are working hard to keep the Newton alive. Good for them.
