The Rasti Computer, which Chen writes is 'derived from the German compound word 'Rasterrahmen' (grid + framework), has at its core the mainboard, battery, and antennae from the highly modular and repairable first-generation Framework laptop. It takes input from the custom keyboard Chen designed for the chassis, with custom PCB and 3D-printed keycaps and case. It sends images to a 10.4-inch QLED 1600×720 display, and it all fits inside a bevy of 3D-printed pieces with some fairly standard hex-head bolts.
Chen's project derives from, and pays tribute to, the Grid Compass (styled 'GRiD' by its maker, GRiD Systems Corp.). The Compass was probably (again, probably) the first clamshell-style laptop made. It saw use by NASA's Space Shuttle program, as well as by military and other entities needing a laptop that was both compact and throw-it-at-a-wall durable. It had 256KB of memory by default (less than half the amount Bill Gates didn't say you should ever need), a 320×240 pixel screen, and an Intel 8086 processor. Some models contained a 1,200bps modem. It cost more than $8,000 in 1982, or almost $25,000 today.
