Responding to: ???'s previous message
Those 5-volt-compatible FPGA's can function to support, as well as to replace the 805x.

Of course, the larger, newer, multi-voltage types are the ones that I'd use to replace the entire system, i.e. ROM, RAM, and I/O, as well as the MCU core, as they're large enough to contain the entire device. They're often not at all cost effective.

Unfortunately, unless the device can interface with 5-volt devices, the cost of level shifters quickly makes the system cost prohibitive.

   Why oh why didn\'t the Horse tell me?            01/01/70 00:00      
      This particular horse thought you knew            01/01/70 00:00      
      This "horse" doesn't want you to notice            01/01/70 00:00      
         This horse won the race!            01/01/70 00:00      
            Every bit of it is on their website!            01/01/70 00:00      
         been there, done that            01/01/70 00:00      
            do they still make FPGA's that small?            01/01/70 00:00

                  a colleague said, \"the gates are free\"            01/01/70 00:00      
                     maybe for small parts            01/01/70 00:00      
                        depends on where you get pricing            01/01/70 00:00

                     What I like to compare is a 33-bit AND gate            01/01/70 00:00      
                     CycloneII is the way to go            01/01/70 00:00      
                        Well, most 805x's run at 5 Volts ...            01/01/70 00:00      
                           well, nope            01/01/70 00:00      
                              depends on how you use 'em.            01/01/70 00:00      
                                 do you read the posts or just the titles?            01/01/70 00:00      
                                    Yes, I read 'em, but that doesn't make it so ...            01/01/70 00:00

               other choices            01/01/70 00:00      
                  and there's Altera's MAX-II, too            01/01/70 00:00      
                     all different manufacturers            01/01/70 00:00      
                        ah ha well portablitly yes and no,            01/01/70 00:00
