Yes, the G1000 software will interface with predict.
I will come out with a few bits of software, for predict, gpredict, and a perl module.
Right now I can manual control the g1000 by using cat.
I do plan to release further details later, possibly get a published article.
I can tell you the cost and features.
the Goldberg-1000 will sell for about $50 a pop, mainly due to the cost of manufacturing boards
It uses a FTDI232R USB serial ship, so it shows up as a USB serial interface in Windows, Mac, And Linux with kernels 2.4 and newer I believe. It has over voltage protection on the sample pins.
It is really small, 1 inch by 1 inch and a half roughly.
If you would like to help with the computer programs that is fine, they will be under the GPL License, not sure which one yet.
