[HP41] New storage drive on ARM (Raspberry PI2+PILBox+HP-IL+USB-Storage)

[Chr Yoko]

Thanks you Floppy for that interresting project.

RPi are now quite difficult to find on the market, so for my new 3D printer that needed one for control , i replaced the BOM's RPi by a "Stick PC" running a Celeron (that kind of tiny stick size PC that you plug to your TV HDMI port).

Win 10 was pre-installed on the internal SSD, but i replaced it by an Ubuntu Server version for Klipper printer controler.

So it may be possible to replace the RPi+SD by a Stick PC easy to find on Amazon and Ali.
A bit like an hammer to crush a fly, but that should work.

An other cheap and elegant option might be to use a Black or "Blue Pill" tiny board using an STM32 micro-controller similar to the one inside the largest SwissMicro calculators.
But that solution would need some good level of programing to get the HPIL layer and the cassette/diskette emulation working onto the STM32.
