Sorry for the advertisement, but I thought this would be of particular interest to the folks on these lists. Some time ago I mentioned that I was working on a clock synthesizer board that could be used (among other things) to get much better timekeeping for applications like NTP. The idea is to replace the motherboard crystal with a connection to the synthesizer, which can be programmed to generate the correct frequency when driven by a higher quality external oscillator. The end result is a PC clock that's far more accurate and stable than the original crystal can provide. I'm pleased to announce that my project worked out, and TAPR is now taking orders for the "Clock-Block" as a fully-assembled unit (however, you'll still have to do some soldering on your motherboard to replace the crystal with the connection to the Clock-Block). We are having the first batch manufactured now, and hope to begin shipment within a couple of weeks. I'm pleased that we'll be able to offer the assembled unit for a price not much more than I originally thought a kit version would cost; the circuit uses surface mount parts that might be challenging for some folks to solder, so offering it assembled makes life easier for everyone. There's more information about the Clock-Block, and you can place an order, at http://www.tapr.org/kits_clock-block.html John PS -- if you're not familiar with TAPR (http://www.tapr.org), it's a non-profit organization that does research and development for the ham radio and amateur electronics enthusiast community. I've been involved with the group for many years and have developed several projects for TAPR, but have no financial interest in the organization or any of its products other than as a member.
