One idea I've been vaguely mulling over for a while is to emulate a 32-bit system on a 8-bit embedded processor. While this does sound insane, and does have obvious performance issues, it would allow

Thank you ... I also recognized now that the STM32G4 alreaedy are available in QFN32 / 5x5 mm, and this is fine for me (STM32G4 including 500kB ROM / 140kB RAM and Floating point)... . And I understa

Remember that old home computers had their BIOS/device handlers, basic filesystem and BASIC implemented entirely in a 32KB ROM and were still working within 16KB of RAM, leaving 16KB for the devices

This will require significant changes to the Lua VM, and I don't think it will be worth the effort. You say speed is not a priority, but running Lua on a microcontroller _that_ small with so little m

It supports asynchronous completions (i.e. a read or write of a block of data), using a kernel-managed thread pool and callbacks. This is likely why native SSL is implemented differently in Windows,
