Micro-Professor MPF-I (original) (raw)
Microprofessor I (ou MPF 1), foi o primeiro computador doméstico primitivo produzido pela Multitech (que mudaria seu nome para Acer em 1987), projetado para uso por hobistas e para treinamento em microeletrônica e Assembler para a UCP Z80. Em 24 de fevereiro de 1993, a Flite Electronics de Southampton, Inglaterra, na época uma distribuidora internacional da Acer, adquiriu desta os direitos sobre o MPF 1, incluindo o firmware e os manuais de treinamento. Isso faz do MPF 1 um dos mais antigos microcomputadores sob venda contínua em todos os tempos.

| dbo:abstract | El Microprofessor I (MPF 1), introduït el 1981, va ser el primer computador de marca d'Acer, llavors conegut com a Multitech, i probablement un dels computadors venuts per més llarg temps. A principis de 2005, encara era al mercat. El MPF I és un sistema d'entrenament simple i barat per al microprocessador Zilog Z80. El MPF 1 no semblava un ordinador. La versió original va ser inclosa en una carcassa plàstica barata en forma de llibre formada al buit, usada generalment per emmagatzemar una còpia de llibres de textos d'ensenyament de llenguatge i dos cassettes d'àudio. Quan estava tancat, el MPF 1 es podia col·locar en un prestatge i aparentava ser un llibre. (ca) Microprofessor I (MPF 1) ist ein Einplatinencomputer, der im Jahre 1981 auf den Markt gebracht wurde. Der Computer wurde von der taiwanischen Firma Multitech (heute Acer) hergestellt. Er gehört wohl zu den am längsten verkauften Computern, die seit dem Verkaufsstart nicht mehr verändert wurden. Der MPF I war ein einfach zu nutzendes Trainingssystem für den Z80-Mikroprozessor von Zilog mit einer Taktfrequenz von 1,79 MHz. Der Rechner war mit einem RAM von 2 KB (erweiterbar bis 4 KB) und einem ROM von 2 KB (erweiterbar bis 8 KB) ausgestattet. Nachfolger des Rechners waren der Microprofessor I-b (welcher zusätzlich ein BASIC-ROM hatte und alternativ zu Assembler die Programmierung in dieser Hochsprache erlaubte), Microprofessor II und Microprofessor III. * I/O-Port: PIO (Programmable Input/Output) Port 8255, insgesamt 24 parallele I/O-Leitungen * I/O-Adresse: 00–03. PIO, insgesamt 16 parallele I/O-Leitungen * I/O-Adresse: 80–83h Programmable CTC (timer unit), insgesamt vier unabhängige Zeitlaufsteuerungen * I/O-Adresse: 40–43h * Anzeige: sechsstellige, rote Sieben-Segment-LED-Anzeige, 1,7 cm * Tastatur: 36 Tasten bestehend aus 19 Funktionstasten, 16 hexadezimale Tasten und eine frei programmierbare Taste. * Lautsprecher: eingebaut, Durchmesser 57 mm, ca. 200–10.000 Hz. * Erweiterungsbereich: Auf der Leiterplatte sind 8,9 cm × 3,5 cm Fläche zur beliebigen Erweiterung vorgesehen. * Tonbandschnittstelle: Anschlussmöglichkeiten für beliebige Tonbandgeräte, Datenrate 165 bit/s. * Systemfrequenz: 3,58 MHz Quarz, Teiler 1:2, Pulsdauer ca. 0,56 µs. * Versorgungsspannung: 5–12 V, 500 mA. Bis heute wird der Computer von Flite Electronics International hergestellt und verkauft. In Deutschland wurde der Mikroprofessor über längere Zeit durch den Lehrmittelanbieter Christiani vertrieben.

A principios de 2005, todavía estaba en el mercado. El MPF I es un sistema de entrenamiento simple y barato para el microprocesador Zilog Z80. El MPF 1 no parecía una computadora. La versión original fue incluida en una carcasa plástica barata en forma de libro formada al vacío, usada generalmente para almacenar una copia de libros de textos de enseñanza de lenguaje y dos casetes de audio. Cuando estaba cerrado, el MPF 1 se podía colocar en un estante y aparentaba ser un libro. (es) The Micro-Professor MPF-I, introduced in 1981 by Multitech (which, in 1987, changed its name to Acer), was the first branded computer product from Multitech and probably one of the world's longest selling computers. The MPF-I, specifically designed to teach the fundamentals of machine code and assembly language, is a simple and easy to use training system for the Zilog Z80 microprocessor. The MPF-I does not look like a typical Microcomputer. It is enclosed in a vacuum formed plastic book case often used to store a copy of a language textbook, two audio cassettes, and a training manual. When closed, the MPF-I can be placed on a bookshelf for easy storage and looks just like a book or a file. This form factor made the computer more appealing to the buyers, since it could be stored away with ease, and it could blend in with the office or home. Programs are entered into the MPF-I using Z80 machine code in hexadecimal format. The MPF-I monitor program displays both an address and data stored at that address simultaneously using a seven-segment display. There is a spare DIP socket for adding additional ROM or RAM to the MPF-I. There are also two 3.5mm audio jacks on the top right of the computer, these are to communicate with the audio cassettes that are used to store programs and code typed into the machine. One is used to read the drive and the other is used to write data; on a conventional audio cassette deck the wires would be connected to the headphone and microphone ports. This type of data storage is similar to that of a Radio Shack TRS-80 or the Sinclair ZX-81, which similarly used audio cassettes to store programs the user typed, as well as commercial programs and games the user could buy. Later Multitech introduced a Tiny-Basic for the MPF-1. The Monitor and Basic fitted into one 4 kByte ROM, replacing the 2 kByte monitor-only ROM. This configuration was marketed as the MPF-1B. In 1984 Multitech introduced the MPF-1P or MPF-Plus, a basic computer that was an evolution of the MPF-1 as it had the same form factor. It featured a single line 20-digit, 14-segment fluorescent display and a click-type QWERTY keyboard. It had the same expansion connector as the MPF-1 (strictly a Z80-CPU pin-header), so several of the MPF-1 expansion boards could be used on the MPF-1P. It was more a Basic computer than the MPF-1, with an assembler and disassembler as part of the firmware (8Kbyte). The MPF-1P featured 4 kByte static RAM. 1985 saw the release of the MPF-I/88, the latest in the MPF-I line. It was an Intel 8088 based single board computer with a two-line LCD screen. On 24 February 1993, Flite Electronics International Limited in Southampton, England, at that time an international distributor for Acer, purchased the copyright to the MPF-I's training manuals, as well as its firmware and hardware intellectual property rights from Acer. Flite is still manufacturing small batches of the MPF1B at a sub-contract manufacturing facility in Havant England (en) Il Microprofessor I, presentato nel 1981 da Multitech (che nel 1987 ha cambiato nome in Acer), è stato il primo computer marchiato Multitech e uno dei computer più a lungo venduti. Il Microprofessor I è costituito da una scheda elettronica basata sul processore Zilog Z80: è progettato per insegnare i fondamenti del linguaggio macchina e dell'assembly. Il Microprofessor I non ha le sembianze di un classico microcomputer: è racchiuso in un involucro plastico sigillato a forma di libro che può contenere il manuale del linguaggio, 2 musicassette e un manuale di apprendimento. Quando è chiuso, ha le sembianze e gli ingombri di un libro e può pertanto essere piazzato in una libreria o portato con sé comodamente. Il 24 febbraio 1993 Flite Electronics International Limited, con sede a Southampton, Inghilterra, distributrice dei prodotti Acer, ha acquistato da questa i progetti e i diritti sull'hardware, sul firmware e sui manuali del Microprofessor I, continuando a produrlo e venderlo fino ai giorni nostri come Microprofessor MPF-1B Z80 Training System.
