For a bit of entertainment, check out http://www.cs.rochester.edu/users/faculty/nelson/cesium/ which is the apparent home of the Cesium-lover's guild. There's no index page, but I suggest you check out the FAQ first, and then the "Songs of Cesium", some of which are quite amazing. The focus is ma

I've seen several of these for sale on Ebay with various options and configurations. Is there any software available to communicate with this unit? A terminal program might work, but one would have to know the PRR-10's ASCII command set. I have looked into this with the usual searches and inquirie

This is kind of off topic but since we are discussing astronomy,.. Has anyone heard if NASA is going to put up a site where we can view the meteor collision video after they process it? Or for that matter, even the raw footage. Chuck ___ time-nuts maili

RE: [time-nuts] GPS clock to RT-Linux for pulsar machine

You can always crank up the clock rate in a custom application and generate the 18.2 Hz system timer interrupt yourself, though. There's nothing inherent about DOS that prevents you from doing precision timekeeping with it. That's not to say it's fun. -- john, KE5FX > In message <[EMAIL PROTECT
