When Computer Chronicles debuted as a national program in the fall of 1983, the IBM Personal Computer dominated what was then still called the microcomputer market. But the PC standard had yet to cement itself as the only approach to small business computers. Hewlett-Packard, one of the original Silicon Valley companies, offered its own MS-DOS machine, the HP-150 Touchscreen Personal Computer. Cyril Yansouni, the general manager of HP's personal computer division, appeared in the inaugural Chronicles broadcast to demonstrate the HP-150 and explain how its touchscreen display and 3.5-inch floppy disk drives help drive the evolution of the micro forward.Computer Chronicles Revisited 1 — The HP-150 TouchscreenComputer Chronicles #101 — Mainframes to Minis to Micros (1983)"The HP 150" (Phil Lemmons and Barbara Robertson, Byte, 1983)"Hewlett-Packard Demonstrates the HP-150 Personal Computer" (Boston Computer Society/Computer History Museum, 1983)HP 150 Technical Reference Manual (1984)"Cyril Yansouni: HP veteran takes risks" (Stewart Wolpin, Professional Computing, 1984)"Jesus He Knows Me" (Genesis, 1991)"Read-Rite Gets Its Act Together" (Arthur M.
