Клон ZX-Spectrum "Москва-128К"
|
||||
# Москва-128
|
||||
|
||||
Данный клон компьтера ZX Spectrum появился, ориентировочно в 1989 году.
|
||||
|
||||
Считается первым отечестывенным клоном с ОЗУ в 128 КБ. Предположительно, является прообразом известного клона
|
||||
|
||||
Особенностями модели являются:
|
||||
* Интерфейс принтера ZX LPRINT III, позволяющий выводить на печать текст программ. Параллельный интерфейс типа Centronics.
|
||||
* Возможность подключения 2-х джойстиков. Типа Interface-2.
|
||||
* Пять программируемых клавиш.
|
||||
|
||||
Схема и печатная плата восстановлены со старых сканов и фото, найденых на сайте zx-pk.ru.
|
||||
|
||||
|
||||
Шаг отверстий 2,54мм. Системный разъем, 3x32пин - DIN41612C-96FR. Диодные сборки заменены на обычные диоды типа 1N4148 (КД521 и т.п.).
|
||||
|
||||
Читалка на операционнике заменена на классическую на компараторе К554СА3.
|
||||
|
||||
По возможности, были исправлены явные ошибки. Переименованы сигналы, с цифровых обозначений на буквенные, принятые в спектрумостоении :)
|
||||
|
||||
Первая версия печатной платы, еще не изготавливалась и не тестировалась.
