Введение
Персональный компьютер Apple Macintosh Classic II (также продается как Performa 200) — персональный компьютер, разработанный и изготовленный компанией Apple Computer, Inc. с октября 1991 года по сентябрь 1993 года. Система имеет компактный дизайн с интегрированным 9-дюймовым монитором, типичным для самых ранних моделей Macintosh. Ручка для переноски, отлитая в корпус, обеспечивала определенную мобильность в то время, когда ноутбуки были еще относительно редкостью. Как и предшествующий Macintosh SE/30, Classic II был оснащен 16-МГц процессором Motorola 68030, но демонстрировал примерно на 30% более низкую производительность из-за ограничений, налагаемых сниженной стоимостью 16-битной шины данных, по сравнению с 32-битной шиной, использованной в конструкции SE/30. Система имела базовую конфигурацию памяти 2 МБ с верхним пределом 10 МБ и поставлялась с жестким диском объемом 40 или 80 МБ. Хотя Classic II был стилизован по образцу более ранней Classic, архитектурно он имел больше общего с Macintosh LC. Использование специализированных интегральных схем, идентичных тем, что использовались в LC, позволило Classic II иметь меньшее количество компонентов, чем у более старых моделей Mac, что снизило производственные затраты. В отличие от LC и SE/30, Classic II не имел внутреннего слота Processor Direct Slot, что сделало его вторым настольным Macintosh без слотов после Classic. Classic II является одной из трех машин, которые были первоначально переупакованы в Macintosh Performa при первом представлении бренда в сентябре 1992 года для конкуренции в сегменте домашних пользователей. Classic II — последний компактный Macintosh с черно-белым дисплеем и последний настольный Macintosh, включающий внешний порт для дисковода гибких дисков. Apple прекратила поддержку Classic II 1 января 2001 года.
The Macintosh Classic II (also sold as the Performa 200) is a personal computer designed and manufactured by Apple Computer, Inc. from October 1991 to September 1993. The system has a compact, appliance design with an integrated 9" monitor, typical of the earliest of the Macintosh range. A carrying handle moulded into the case added a degree of portability at a time when laptops were still relatively uncommon. Like the preceding Macintosh SE/30, the Classic II was powered by a 16 MHz Motorola 68030 CPU but experienced about 30% slower performance due to the limitations imposed by a cost reduced 16 bit data bus, versus the 32 bit bus used in the SE/30 design. The system had a base memory configuration of 2 MB, with a 10 MB upper limit and was supplied with either a 40 or 80 MB hard disk. '''While the Classic II was styled after the earlier Classic, architecturally it had more in common with the Macintosh LC. The use of custom ICs, identical to those used in the LC, enabled the Classic II to have a lower component count than older Macs, which reduced manufacturing costs. Unlike the LC and the SE/30 before it, the Classic II lacked an internal Processor Direct Slot, making it the second slotless desktop Macintosh after the Classic. The Classic II is one of three machines to be originally repackaged as a Macintosh Performa when the brand was first introduced in September 1992 to compete in the home user space. The Classic II is the last black and white compact Macintosh, and the last desktop Macintosh to include an external floppy disk drive port. Apple discontinued support for the Classic II on January 1, 2001. Models

The Classic II has a 50 pin internal expansion slot intended for either an FPU co processor or additional ROM. The socket is unsuited for use as a general purpose expansion slot. Apple never produced an expansion card for this slot, although third party FPUs were available including the FastMath Classic II by Applied Engineering and Sonnet offered a synchronous (16 MHz) and asynchronous (50 MHz) 68882 FPU. Retro computing hobbyists have also subsequently produced open source designs for this slot. The main board from the Classic II (left) contains the logic for the system. High voltage components such as the PSU and CRT driver circuitry were on a separate "analogue" board. The 68030 CPU can be seen on the right, which is next to the FPU/ROM expansion slot. Two ROM chips in sockets are below the CPU. The RAM is to the bottom left. This model contains 4MB, of which 2MB is soldered to the board and 2MB is in SIMM sockets. Just above the RAM is the Apple "Eagle" chip which contains video interface circuitry and glue logic. Above that is an AMD manufactured SCSI controller and serial chip, close to an internal and external SCSI connector used to attach hard disks or other peripherals. There is a PRAM battery carrier to the left of the CPU (the battery is not present) with an internal floppy drive connector just above it with the floppy controller chip on the left. To the right of the floppy connector is an 8 bit microcontroller which manages the ADB bus.

Расширение: Коннекторы на задней панели включают порт ADB для клавиатуры и мыши, два мини-DIN 8 RS 422 последовательных порта, DB 25 SCSI, DB 19 для внешнего дисковода гибких дисков и два 3,5-мм аудиоразъема для аудиовхода и выхода для наушников. Classic II имеет 50-контактный внутренний слот расширения, предназначенный для FPU-сопроцессора или дополнительной ПЗУ. Слот не подходит для использования в качестве слота расширения общего назначения. Apple никогда не выпускала карту расширения для этого слота, хотя сторонние FPU были доступны, включая FastMath Classic II от Applied Engineering и Sonnet, предлагавшие синхронный (16 МГц) и асинхронный (50 МГц) 68882 FPU. Энтузиасты ретро-компьютеров также впоследствии создали проекты с открытым исходным кодом для этого слота. Основная плата Classic II (слева) содержит логику системы. Высоковольтные компоненты, такие как блок питания и схемы управления ЭЛТ, располагались на отдельной "аналоговой" плате. Процессор 68030 можно увидеть справа, рядом со слотом расширения FPU/ROM. Два чипа ROM в сокетах расположены под процессором. Оперативная память находится внизу слева. Эта модель содержит 4 МБ, из которых 2 МБ припаяны к плате, а 2 МБ — в SIMM-сокетах. Прямо над оперативной памятью находится чип Apple "Eagle", который содержит схемы видеоинтерфейса и логику согласования. Над ним расположен SCSI-контроллер и последовательный чип производства AMD, расположенные рядом с внутренним и внешним SCSI-коннекторами, используемыми для подключения жестких дисков или других периферийных устройств. Слева от процессора находится держатель батареи PRAM (батарея отсутствует) с внутренним разъемом дисковода гибких дисков непосредственно над ним и чипом контроллера дисковода слева. Справа от разъема дисковода находится 8-битный микроконтроллер, который управляет шиной ADB.
