@smittytone @neil @rogerlipscombe I'd recommend a 3MX if possible—the soap-on-a-rope RS232 dongle for the 3/3A/3C is ridiculous. Also stock up on memory cards for that maximum 16Mb of fixed storage! Raaaar!
Really, it was gorgeous design in the 1990s but it's very obscure retrocomputing today. And watch out for the hinges and screen cable fracturing with age.
