This is the "SPACE ISLAND LC-1000" electronic calculator, which enjoyed a brief golden age from the 1970s to the 80s. ■ A Quiet Light Emerging from the Darkness The greatest appeal of this calculator lies in the beauty of its "vacuum fluorescent display (VFD)," which cannot be replicated by modern LCD screens. The moment you turn it on, clear, blue-green numbers, like the deep sea or distant stardust, emerge from the darkness. It's not just a "display" for office use. The light emitted within the vacuum glass tube is somehow warm, and just by looking at it, you can feel the "longing for the future" that the engineers of the time held. ■ A Small Universe Called SPACE ISLAND As the brand name "Space Island" suggests, the green numbers that illuminate its jet-black body are like islands floating in a pitch-black universe. The feel of the keys on your fingertips, and the brief lag as the calculation results light up. All of this gives you a luxurious and relaxed time, something that is often sacrificed in today's efficiency-driven world. ■ After many years, this unit is still working well and displaying numbers beautifully. There are minor scratches due to aging, but they are also the "texture" of the history this calculator has lived through. The glow of the VFD is also clear, with no defects. ■ A Touch of Poetry for Your Desk Of course, you can use it as a calculator, or you can simply leave it lit as an object in your study at night. Just by doing that, the atmosphere of the room will become a little gentler and more nostalgic.
