Have you ever considered making a standalone HD20 product? Something cheaper than floppy emu that has no screen or buttons. Just A DB-19 connector,a series of diagnostic LEDS, an sd slot, and maybe a header to connect a floppy emu…

Could you add the ability to floppy emu to measure voltages?

A rom kit for Classic II would be nice since it seems that the Logic board will accept 4mb total for rom...
