right SAGE Computer Technology was a computer company based in Reno, Nevada, United States. It was founded in 1981 by Rod Coleman, Bill Bonham and Bob Needham; it went through several name changes. The change from Sage computer came about when "Sage Software" in Maryland demanded the cease of using the name Sage in the computer segment.〔 * SAGE Computer Technology ::- created the Sage II and Sage IV computers based on the Motorola 68000 microprocessor. * SAGE Computer *Stride Micro * *MicroSage Computer Systems (a wholly owned subsidiary, 1987) ::- created the Stride 420, Stride 440, Stride 460 (VME),〔 090428 entertainment.webshots.com〕 Stride 660 and Stride 740 computers. == SAGE IV == The SAGE IV was released in 1983.〔 101014 thebattles.net〕 Hardware: * Board0: CPU: MC68000 @ 8 MHz, 2× serial RS-232 ports 19.2 kbit/s, Parallel input/output (PIO) for printers, GPIB, Floppy disc controller, 512 KByte DRAM. Same as in SAGE II.〔 090427 old-computers.com〕 * Board1: 4× serial RS-232 ports 19.2 kbit/s, Hard disk controller, 512 KByte DRAM.〔 * Memory consist of 64 Kbit 150 ns memory modules. Parity error protected setup. 〔 090428 bp0.blogger.com〕 * Minimum system memory is 256 KByte.〔 090428 sageandstride.org〕 * Storage: 1× 5¼" 800 KByte F.D. drive. 1× 5 - 40 MByte Winchester harddisk. * Built-in multi-user BIOS.〔 * Introduced in November 1982 * Price: 3600 USD (for the single-floppy entry-level configuration) The SAGE managed multitasking with six serial ports in real time with 1 MByte of RAM in 1983. It was used by scientists and engineers for more than ten years when it was popular. "running over 10 years with zero admin, and maybe even zero reboot."〔 "13 times faster than the Apple II" (when introduced).〔 090427 suddendisruption.blogspot.com〕 Sage IV computers were used for the development of the Amiga prototype computer system "Lorraine". The Sage system got the nickname "Agony".〔 090427 floodgap.com〕 Access was through a serial video terminal. Graphics capability was possible with the addition of a third-party colour graphics system from Robinson Systems which plugged directly into the Sage 68000 bus and provided output compatible with a range of colour monitors (e.g. Cotron Sword, Electrohome 1301). The included operating system was the UCSD p-System. Many other operating systems were available〔 090921 sageandstride.org〕 including CP/M-68K, Idris, PDOS, HyperFORTH Plus, BOS, TRIPOS, Mirage, and MOSYS. Programming languages available included Pascal, Modula-2, C, FORTRAN77, BASIC, 68000 macro assembler, APL, LISP and Forth. The MC68000 CPU were introduced in 1979 by Motorola. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SAGE Computer Technology」の詳細全文を読む スポンサード リンク
