小教授一号(MPF I)是一款在1981年上市发表的个人计算机。它是宏碁(当时英文品牌名叫Multitech)的第一种品牌计算机产品,并可能是世界上卖得最久的计算机之一。直到2006年,它仍被位于英国南安普敦的Flite电子国际制造贩卖。小教授一号是一种针对Zilog Z80微处理器所开发、很易学易用的训练系统。
小教授一号看起来不像计算机,其最原始的版本是被封装在真空成形(铸造)的塑料盒中,这种盒子通常还装着语言课本、两卷录音带以及一本训练手册。当盒子关上时,它可以被放置在书架上以方便存放,且看起来就像是一本普通的书。
Microprofessor I (MPF 1), introduced in 1981 by Multitech, who changed their company name to Acer in 1987, was their first branded computer product and probably one of the world's longest selling computers. The MPF I, specifically designed to teach the fundamentals of machine code, is a simple and easy to use training system for the Zilog Z80 microprocessor.
The MPF 1 does not look like a computer. It is enclosed in a vacuum formed plastic book case usually used to store a copy of language textbook and two audio cassettes as well as a training manual. When closed, the MPF 1 can be placed on a bookshelf for easy storage and looks just like a book.
On the February 24, 1993, Flite Electronics International Limited in Southampton, England, at that time, an international distributor for Acer, purchased the copyright to the MPF1's training manuals, as well as its firmware and hardware intellectual property rights from Acer.
Currently, it is still being manufactured and sold by Flite Electronics International.

谈到台湾的资讯产业,不能不介绍台湾宏基电脑集团。宏基集团的老板叫施振荣,他在世界电脑行业中是赫赫有名、风云一时的人物。1976年,以施振荣为首的5名年轻人白手起家,涉足资讯产业,在度过了艰难的起步阶段后,80年代进入成长期。
1981年,宏基电脑在台湾新竹科学园区设立第一个厂房,时至今日,它已成为台湾最大的自创名牌电脑厂家,也是目前全球第七大个人电脑制造商,在全世界竞争最激烈的美国市场上亦进入前10名。1997年,施振荣作为亚洲唯一的代表,出席了在美国举行的亚太信息高峰会议,他在会上作了《以亚洲人的眼光看信息产业》的专题发言,激起电脑资讯业的强烈反响。
施振荣认为宏基电脑不应该跟在别人后面走,他说,那样顶多只能成为二三流的企业。他立志要在欧美垄断的电脑领域创造出自己响当当的名牌。1981年,宏基开始在海外推广第一个自创名牌产品———“小教授一号”。经过多年的精心培育,“小教授一号”终于在市场上打响了,经评定,这一品牌价值2000万美元。
就在“小教授一号”蒸蒸日上的时候,施振荣出人意料地决定放弃它,重新创立“Acer”品牌。他的合作伙伴们大惑不解,施振荣解释说:“小教授一号”的英文太雷同,不利于推广。而“Acer”是拉丁字,有“积极、有活力”之意,还隐含着“王牌”的意思,而且不重名,在法律上能够得到保障。事实印证了他的远见。“Acer”出来后一炮打响,很快走红市场,被美国的鉴定公司评估价值1.8亿美元,成为连续多年蝉联国际知名度最高的台湾品牌电脑。

小教授二号(MicroprofessorII,MPF II)在1982年上市发表。它是宏碁(当时英文名为Multitech)的第二种品牌计算机产品,也是一种最早的苹果计算机复制机。它看起来并不像大部份其它个人计算机。它的机箱是长方形的塑料盒,正面下方嵌着小型的软胶键盘。
在1983年,小教授二号在英国贩卖,含税零售价是269英磅。
MPF II一个重要的功能是它的中文培基。它是一种基于Applesoft BASIC中文化的BASIC语言。
与Apple II的不同
小教授二号并不完全与AppleII兼容。
小教授二号没有AppleII的文字模式。所有的文字都是由软件"画"在屏幕上,而不是经由硬件产生。这在当时是使计算机能显示中文的唯一最具经济效益的方式,因为当时基于硬件的中文产生器要价上百美元。
如同Apple II,小教授二号有两个图形缓冲器,但第二个缓冲器在地址A000H,而Apple II的在4000H。
MPF-II的键盘接口相当简单,是由一个8位输出口及一个直接连结至键盘矩阵的输入口组成。它没有苹果的游戏杆接口,取而代之的是键盘方向键与两个功能键。

小教授三号编辑本段回目录
小教授三号(英文:MPFIII)在1983年上市发表。它是宏碁(当时英文名叫「Multitech」)的第三种品牌计算机产品,也是一种早期的苹果计算机复制机(一种AppleIIe复制机)。与前两代小教授不同的是,它的设计受到IBM PC的影响。由于它在ROM里的增强功能以及不同的图像程序,小教授三号与Apple IIe并不完全兼容。
MPF III包含了一块可选择的Z80CP/M模拟卡。它能使计算机切换到Z80处理器并运行设计给CP/M操作系统的软件。

The Micro-Professor MPF-1P is a low cost, versatile microcomputer system featuring sophisticated system featuring sophisticated software and hardware capabilities.
It is not only ideal for those who intend to familiarize themselves with micro-processing and advanced microcomputer hardware and software, but also can be used for many dedicated purposes and OEM applications such as industrial control and instrumentation.
The resident "monitor" program is basically responsible for running the system, loading and saving data, and executing programs. It controls access to the resident assembler, BASIC, disassembler, editor, printer and software control.
The Micro-Professor requires a single 5vdc/450mA power supply (9vdc external), with a 4xAA battery holder to prevent menory loss during power loss.
The MPF-1P has a blue/green vacuum flourescent display, capable of displaying 20 characters at once.
The cassette interface is capable of reading and saving data at up to 165 bits/second.
The on-board 2.25-inch speaker, under program control, allows sounds and alerts for the user.
Multitech was the original creator of the Micro-Professor line of systems, but they were eventually renamed as Acer computer systems in 1987, and continued to sell Micro-Professors past 1988.
Other options available include:
PRT-MPF-1P | thermal printer |
