Logic, yes. Remember, a FPGA is a programmable device so the logic is in the form of software. To use a FPGA to replace a GIME would be an expensive task. Many FPGA's are 3v core so you would have to convert many of the signals from 3.0v to 5.0v logic levels. Is it possible? yes, I think so but it would be expensive to devlope and just not practical IMHO.

But wouldn't for FPGA_CoCo need to have reproduced the logic GIME chip?Sent via BlackBerry by AT&T-----Original Message-----From: "T.

The GIME chip was a custom chip made by tandy. They discontinued the part years ago so when it goes... Ebay "for parts" it should go!-----Original Message-----From: Jeremy Michea [mailto:jmichea at bell.net]Sent: Wednesday, March 6, 2013 05:27 PMTo: coco at maltedmedia.comSubject: [Coco] [Color Computer] Re: Is this worth the buy?So if I hear this conversation correctly, Gime chips are irreplaceable and if one goes on one of our beloved coco 3’s we essentially have a nice paper weight?Now I’m concerned I have an infamous “86” chip in one of mine. Oh the stress of a hobby in old electronics. --Coco mailing listCoco at maltedmedia.comhttp://five.pairlist.net/mailman/listinfo/coco--Coco mailing listCoco at maltedmedia.comhttp://five.pairlist.net/mailman/listinfo/coco--Coco mailing listCoco at maltedmedia.comhttp://five.pairlist.net/mailman/listinfo/coco
