dbo:abstract
  • Der SYM-1 war ein Einplatinencomputer, der von der US-amerikanischen Firma Synertek im Jahre 1978 auf den Markt gebracht wurde. Der Rechner trug ursprünglich den Namen VIM-1 (Versatile Input Monitor), der Namen wurde aber aus rechtlichen Gründen im Jahre 1978 abgeändert. Der SYM-1 war ein Konkurrenzprodukt zum populären MOS Technology KIM-1. Beide Produkte waren in hohem Maße baugleich und kompatibel. Im Vergleich zum KIM-1 konnte der SYM-1 alleine mit einer +5 Volt-Stromquelle betrieben werden, hatte einen umfangreichen Monitor-ROM, besaß drei konfigurierbare ROM/EPROM-Sockel und einen RS-232 seriellen Port.Synertek verkaufte ROMs, durch die man auf dem Rechner die BASIC-Programmiersprache und einen Assembler-Editor installieren konnte.

  • The SYM-1 is a single board "trainer" computer produced by Synertek Systems Corp in 1975. It was designed by Ray Holt. Originally called the VIM-1 (Versatile Input Monitor), that name was later changed to SYM-1. The SYM-1 is a close copy of the popular MOS Technology KIM-1 system, with which it is compatible to a large extent. Compared to the KIM-1, enhancements include the ability to run on a single +5 volt power supply, an enhanced monitor ROM, three configurable ROM/EPROM sockets, RAM expandable on board to 4 KB, an RS-232 serial port, and a "high speed" (185 bytes/second, the KIM-1 supports about 8 bytes/second) audio cassette storage interface. It also features on-board buffer circuits to ease interfacing to "high voltage or high current" devices. One capability of the SYM-1 is its ability to allow an oscilloscope to be added to provide a 32 character display under software control. As explained in Chapter 7 of the "SYM Reference Manual", the vertical input, ground and trigger input of the oscilloscope are to be connected to the "Scope Out" connector AA on the SYM-1 board. The "Oscilloscope Output Driver Software" code provided in this chapter of the manual is to be entered into the SYM-1's memory and executed to enable the oscilloscope display. This code provides control of the oscilloscope display, as well as a rudimentary character set. Resistors R42 and R45 are to be adjusted to refine the displayed image. Synertek sold ROMs which could be installed to add the BASIC programming language or a Resident Assembler/Editor (RAE). Synertek contracted with a company called Eastern House Software to port their Macro Assembler/Editor (MAE) into an 8 KB ROM. The author of MAE, RAE, and another version sold by Skyles Electric Works was Carl Moser. MAE was sold in various forms not only for the SYM-1 but also for other 6502-based computers including Commodore, Atari, KIM, and Apple. Other forms of MAE included a cross assembler for 6800 and 8085—and an offering of these cross assemblers was planned for RAE. One of the more subtle features of the SYM-1 is the use of a look up table in the low memory of the 6502. This provides a vectoring function in its operating system to redirect subroutine calls to various input and output drivers, including interrupt servicing. Users are able to develop their own interface routines, and substitute new vectors for the original vectors in the startup UV-EPROM. This seamlessly maintains the normal operation of the board's monitor and languages such as Synertek Systems BASIC. One of the later home/education computers that uses this concept extensively is the BBC Micro produced by Acorn Computers in the UK. Some of the other computer designers of this era failed to grasp the significance of this elegant use of vectors to the software mapping of new developments in hardware. (en)
  • SYM-1 は、1978年ごろ Synertek が開発したワンボードマイコン。当初 VIM-1(Versatile Input Monitor)という名称だったが、法的な問題で1978年の4月から8月の間に改称された。 モステクノロジーの KIM-1 の競合製品であり、多くの点で共通する部分がある(搭載するマイクロプロセッサは同じ 6502)。KIM-1 に対する優位点は、+5V の電源だけで動作できる点、ROM上の機械語モニタ、ROM/EPROMを挿入できるソケットを3つ備えている点、RAMを基板上で4キビバイトまで増設可能である点、RS-232シリアルポート、高速オーディオカセット記憶装置インタフェース(185バイト/s、KIM-1 は 8バイト/s)などである。また、基板上にバッファ回路があり、高電圧機器や大電流機器との接続が容易である。 SYM-1 特有の機能として、オシロスコープを接続でき、それをソフトウェアで制御して32文字表示のディスプレイとして使うことができた。 Synertek は、BASIC言語のROMやアセンブラ/エディタ (RAE) のROMを別売りしていた。また Eastern House Software と契約し、マクロアセンブラ/エディタ (MAE) を 8K ROM で販売していた。RAE や MAE を書いたのは、 Carl Moser である。MAE は SYM-1 だけでなく、他の 6502 を使ったコンピュータ向けにも発売された(コモドール、アタリ、モステクノロジー、Apple)。 (ja)
