Manufacturers of personal computers will take advantage of that, flooding the market with truly small desktop devices by the end of the decade. Real change happened with the start of the '70s, as Intel released the first actual microprocessor, the 4004, with 2,300 transistors in its capacity.

IBM 5100, one of the first computers, made to be used on the move. However, there were attempts as Digital Equipment Corporation (DEC) advertised its 1965 PDP-8 computer as fitting on the back seat of a convertible Volkswagen Beetle. Smaller LOGIPAC and BASICPAC installations that fit inside a military truck.Д®ngineers developed multiple 'portable' computers over the '60s, yet with microprocessors not yet invented, devices could not shrink in size. MOBIDIC was part of a military FIELDATA project. US Army official explains the working of the FIELDATA project. Even though a few tons lighter than the DYSEAC, MOBIDIC also consisted of two trailers, with the second providing necessary power.ДЄptly named after a legendary sperm whale Moby Dick, the device's name was an acronym for 'MObile DIgital Computer.' The key innovation that allowed for a smaller size were transistors (32,000 of them), alongside diodes and magnetic cores. Short five years have passed, and a somewhat 'smaller' device was delivered to the military by Sylvania, a now-defunct electrical equipment manufacturer. No wonder, as the computer was made of 900 power hungry vacuum tubes together with thousands of diodes that accompanied it.ДЄn outline of the MOBIDIC module. Or, to put it simply, a van housed a computer, while another one served as its battery. The first van carried the computer's brain, while the second provided the device with the 12 kW power needed to survive. Calling it 'portable' would be something of a stretch, as the device weighed around 20 tons and took two trailer vans to transport. An excerpt from a YouTube video.Д«uilt by the National Bureau of Standards for the US Military, DYSEAC might be the first computer to be specifically made to be moved from one place to another. One trailer housed a computer while the second one provided power. However, harnessing the power of fast computation proved more important than obstacles like weight and lack of technology. That made the first computer huge and as movable as a large library. Computers relied on vacuum tubes to carry out various calculations.Д®ven though a novelty at the time, vacuum tubes were nothing but small in any modern sense. Now, the problem with the first computer devices, made in the '50s, was that there still were no integrated circuit boards with our beloved transistors. Even if the Z80 weighed 1 gram, 1.8 million of those would weigh 1.8 tons (1.9 US tons). Other factors notwithstanding, it'd take 1.8 million Z80's to replicate the M1.
