  1. MICS 2007 Looking Back In honor of 40 years of the symposium Curt Hill Valley City State University

  2. Teletype • Printing terminal • Teletypes date from the 1920s • Printer • Could communicate over phone lines • Could read and write paper tape Printing terminal for early generation of computers. This model did not have the telephone capability. It was used as the terminal for the Microdata 800.

  3. Microdata 810 • Processor: discrete ICs • Core plane memory 4K • ROM: Discrete diodes • Year 1969 • Cost 6700 One of the two CPU cards is top left, a Read Only Memory card is top right and the two card core memory is center.

  4. Poly 88 • Processor 1.8 MHz 8080A CPU • Year 1976 • RAM 512 Bytes • 16 line by 32 character video One of several S100 bus computers that appeared after the Altair

  5. Apple II + • Processor 1 MHz 6502 CPU • Year 1979 • RAM 32 KB • Storage optional 5¼-inch floppy disk drives (180K) • Display: 40 character display (often shown on regular television) Extremely popular hobby/low end computer. The standard computer in high schools for years. The large sales of the Apple II forced IBM into the market before they were ready.

  6. IBM PC • Year 1981 • Processor 4.77 MHz 8088 CPU • RAM 65 KB • Storage dual 5¼-inch floppy disk drives (360K) • Display: • 80 character × 25 line monochrome CRT display • Color display The first of its kind came out in 1981 and within a month IBM was selling 1 million units per month. Despite the poor comparison with today's technology, these dominated the market of their day. This ended the day when personal computers were built to hobby standards and not professional standards.

  7. Osborne OCC1 • Year 1981 • Processor 4 MHz Z80 CPU • RAM 65 KB • Storage dual 5¼-inch floppy disk drives • Display 5 inch, 52 character × 24 line monochrome CRT display • Keyboard fold down which doubled as the computer case's lid • Weight 23.5 lbs Designed by Adam Osborne, it was the first truly portable computer. It came with its own bundled software and could be purchased for $1795. Because of its all-in-one nature and low price, it was very popular. Too popular, unfortunately. The company suffered from very rapid growth and Osborne computer went out of business in 1983.

  8. Tandy 100 • Year 1983 • Cost $599 • Processor 2.4 MHz 80C85 CPU • RAM 8 KB • Microsoft BASIC in ROM • Some of the routines of the 100 are supposed to have been written by Bill Gates himself. Manufactured by Kyocera, for Tandy (Tandy 100), NEC (PC 8201) and Olivetti (M10)

  9. ZDS Supersport • Year 1986 • Model ZFL-184-01 • Processor Intel 80c88 4.77/8 Mhz • RAM 640 KB • Hard Drive 20 MB • Floppy drive 1.44 MB • Display 10" LCD/CRT • OS DOS • Weight 14 lbs with batteries The Supersport is pictured with the rechargeable Nicad battery (resting on side of display) that attaches to the back of the computer.

  10. IBM PC Convertible • Year 1986 • Model 5140 • Price $2,000 • Processor Intel 80C88 4.77 MHz • RAM 256-640K • Storage 2 built-in 3.5" floppy drives (720K) • OS DOS The IBM PC Convertible was IBM’s first clamshell style laptop. It was a fairly advanced machine for IBM as it was their first use of Surface Mounted Devices (SMDs) on a production machine. The display panel detaches so that a regular CRT may be used.

  11. Macintosh Plus • Year 1986 • Price $2,600 • Processor Motorola 68000 8 MHz • RAM 1 M • Storage 3.5" floppy drives (800K) The first year used a beige color, after that the platinum was used. This is the machine that introduced SCSI.

  12. IBM Thinkpad R52This computer • Type 1860-CT0 • Processor Intel Pentium 4 M 1.8 GHz Processor • Graphics 14.1" XGA TFT and Mobile Intel 915GM Graphics with 128MB • RAM 512 MB • Hard disk 60 GB, 5400 RPM • MouseTrack point • DVD/RAM Drive DVD-RW, CD-RW Combo Optical Drive • Audio SoundMAX Digital Audio • Dimensions 12.3" x 10" x 1.5" • Weight 5.8 lbs – 8.6 with battery and power supply
