Do you remember?
The MR-1 professional cassette deck from Nakamichi offered front and rear balanced inputs, unbalanced inputs, balanced and unbalanced outputs, linear-scale peak-reading meters and independent tape and EQ selection. The unit featured an asymmetrical dual-capstan direct-drive transport with less than 0.027 percent flutter, as well as an exclusive pressure-pad lifter that eliminated scrape flutter and modulation noise. A motor-driven cam operating system ensured gentle tape handling and automatic slack take-up. This was a discrete three-head recording system for 20Hz to 20kHz ±3dB response advertised in 1985.
That was thenDigital Equipment Corporation unveiled the PDP-8 in 1965. This 12-bit machine was the first commercially successful minicomputer. Small enough to sit on a desktop, it sold for $18,000 — one-fifth the cost of a low-end IBM/360 mainframe. The machine used a core memory system that operated at cycle time of 1.5 microseconds. Early PDP-8 models used a front-panel interface, a paper-tape reader and a teletype printer with an optional paper-tape punch. Over time I/O systems such as magnetic tape, RS-232 and current loop dumb terminals, punched card readers and fixed-head disks were added. With its combination of speed, size and cost the minicomputer was incorporated in thousands of manufacturing plants, offices and scientific laboratories. Source: www.computerhistory.org |

Most people relied on radio during the hurricanes in 2004. Listeners repeatedly commented that radio was dependable, used fewer batteries and had better signals than TV, and it was portable.
