The Micro Instrumentation and Telemetry Systems (MITS) Altair 8800 is introduced, sparking the microcomputer revolution. ALTAIR 880 EMULATOR FOR MAC SOFTWAREBelieving, along with Intel's designers, that the microprocessor would run embedded systems such as digital watches, they market their hardware and software together -not as a microcomputer, but as a development system, used for programming 2048- bit (256- byte) Intel 1602A programmable read-only memory (PROM) or erasable 1702A EPROM chips which are plugged into a socket on the Intellec-8's front panel. Kildall's friend John Torode developed the controller hardware while Kildall worked on the disk operating system software. Convinced that magnetic- disk storage would make the Intellec-8 more efficient, Kildall interfaced the computer with an 8-inch Shugart Associates floppy disk drive using a custom built floppy disk controller. Information Terminals Corporation (ITC) introduces the first two-sided, double-capacity floppy disk-the model FF34-2000 flippy disk, compatible with IBM's 8-inch disk. The dominant mainframe at the time, the IBM System/360, can address 2 24 (16,777,216) memory locations, or 16 megabytes (MB) of memory. Intel releases the 8080 (cost $360), which has a 16-bit address bus that can address 2 16 (65,536) memory locations, or 64 KB of memory. The 8-bit 8008 has a 14-bit address bus that can address 2 14 (16,384) memory locations, or 16 KB of memory. īill Gates, Paul Allen and Paul Gilbert develop the Traf-O-Data Intel 8008-based computer. CP/M runs in approximately 3 1 ⁄ 2 kilobytes (KB) of memory. CP/M was finished before the hardware to run it on was completed, by using a PDP-10 to simulate the 8080. The Intellec-8 supported a Teletype operating at 110 baud, a high speed punched paper tape reader and a CRT terminal at 1200 baud. While working as a consultant to Intel, Gary Kildall, an instructor at the Naval Postgraduate School, writes CP/M, a simple "Control Program/Monitor" for an 8-bit Intel 8080 microprocessor-based Intellec-8 microcomputer development system given him by Intel, to test out his PL/M compiler. IBM introduces Winchester hard disk drive technology with the IBM 3340 direct access storage device for use on their System/370 mainframes. IBM introduces the IBM 3740 data entry system, which introduced a new recording medium -a single-sided 8-inch-diameter read/write " memory disk"-the IBM diskette, to replace punched cards.
