[Coco] DriveWire on the DE1

For the last few days I have been doing everything on the DE1. I will update everything for the Xilinx Spartan 3 platform in a few days. Since I have my Sound, Joystick port, and second serial port analog board on the Xilinx platform, I do a lot with it. But when we get all the features of the DE1, sound / SD card, it will be hard to beat. But I intend on supporting all features that the hardware supports on both platforms.

I will post the latest builds for the DE1 on the Yahoo group in a day or so. And will post the builds for the Xilinx boards when I get it working.

Nevermind... Answered my own question.  For the edification of others, 
their Quartus II software package (no Linux support - boo) is available 
for free download and is not time-limited.  It simply lacks some features 
of the pay-through-the-nose commercial version ($3500/yr - ouch).

Question for Gary Becker, if he's listening:  Is the 1M gate Xilinx 
Spartan 3 equally well supported by the CoCo project?  Do you anticipate 
that it will continue to be?

I ask because I'm passingly familiar with the ISE environment and would 
prefer to develop under Linux.  Boards appear to be the same price.
