Old fab != cheap fab. Most of the expense in ASICs is overhead, not fab demand. I'd recommend Actel, which is lower power and nonvolatile. http://www.microsemi.com/products/fpga-soc/fpga/proasic3-overview -Nate On Sep 4, 2013, at 7:48 PM, Justin wrote: > I agree with Gideon, there are fools like me who will spend a lot for toys that make retro hardware more enjoyable or convenient in the modern world. I would still pay too much for a decent auto-switch split composite/RBG-I -> DVI or HDMI converter so that the 128 could be used easily with modern displays. That post about trying to replicate the missing chips for the C65 not too long ago is an obvious opportunity for FPGA equivalents. Then again, 110nm fab is so old and power inefficient now that you might actually be able to get chips in low quantities made at old foundries that are still in operation. > > Justin > > On Sep 4, 2013, at 3:45 PM, Jim Brain <firstname.lastname@example.org> wrote: > >> On 9/4/2013 11:50 AM, Bil Herd wrote: >>> I hadnít thought about power consumption (yet) as I guess I hadnít really come to terms with the fact that something useful for someone restoring old systems would really need the (exact) same footprint (TED) and reasonable power, etc. I was hung up all the way back at cost as I donít know what is considered to be too expensive, but I know what I consider to be too expensive and the different scenarios seemed kind of costly.
