       sad to see so few FPGAs still work at 5V…

       @mmu_man what's the problem with 5V?

       @zerkman it's needed to replace chips in old computers.

       @mmu_man oh, now I get it.Just checked, indeed some FPGAs require external I/O buffers to adapt the voltage.

       @zerkman but when you want to replace, say a PLCC44 package, space is tight.

       @mmu_man that depends how "old" your computer is. It's a small package indeed.

       @mmu_man that icecube or whatever USB FPGA works at 5v, but what is the actual issue? buck/boost exists

       @picofarad when you want to recreate a PLCC44 IC you don't have the room for regulators and buffers.
