Chuck,

There are free CPU cores, etc. Some have dabbled here but there is no  
GIME FPGA, others will say it isn't that hard, etc. Proof is in the  
pudding. If it isn't that hard, then do it, no time, busy, etc...Not  
implying you here.....There is a lot going on in the GIME.

Some have booted to a green screen, etc but we all know that there is  
a lot of work in the details of a project and to get one that works,  
95%+ of the apps requires a bunch of time. Details, details, details.

Then the cost. Last I checked some of the FPGA prices were $250+. Sure  
there are bigger, better and faster ones now but my point is the same.  
This is a labor of love and small volume manufacturing costs more than  
one would think unless they have lived it.

I tip my hat to you and your FDC controller project!!!! Nice job.
