(C) SOBOS/AREAsoft (C) PETERS THIS MYSTERIOUS SPRINTER So, let's get started! In this article, I I'll try to tell you all what it is rulez. So, let's start from the very beginning - nogo - from the hardware. This computer has the following parts and characteristics: CPU Z84C15 - 21 MHz The command system is absolutely compatible with command system Z80, including under- documented commands. Counting this almost complete compatibility with Software written for Spectrum-compatible computers. TURBO mode switches the CPU from frequency Z.SMHz at 21 MHz and makes it possible to work download from FD`s 1.44 Mb. Turn on/off TURBO mode is performed programmatically or in manual. Main RAM - up to 4 Mb, runs for an hour - tote 7 MHz. (72 pin SIMM) High-speed video RAM - 256 Kb (512k). Video output for connecting to a TV (monitor) via video input, or to mohuto- ruCGA type. R signals are supplied to the connector, G, B, Sync, SS, GND, Audio, +5v. ROM 128k (i27C010) High-speed RAM 64k The basis of the entire ALTERA PLM scheme EPF10К1OQC208-4 FD controller on KR 1818VG9Z IBM-AT KLAVA controller. Keyboard emulation ZX cameras and direct scan code input. IDE interface for connecting a hard drive and CD-ROM. STEREO audio output for beeper, hardware emulated AU-Z-Z910, eight- bit COVOX, SOUNDRIVE, SPRINTER SOUND CARD. Kempston joystick, tape input/output move. MS-MOUSE controller. CENTRONICS printer interface. Dba slots with buffering as standard ISA-8. Panel for CMOS clock (DALLAS) Board was developed specifically for installation in MINI-TOWER housing, and therefore has a stan- Dart connectors for connecting a keyboard ry, nutrition, etc. Memory distribution scheme SPRINTER Addressing Page ports CPU ┌----------┐ ┌---------┐ ┌--------------┐│#0000-#ЗFFF├-┤ ПОРТЫ ├-┤ROM_BASIC │ └----┬------┘ │ #7FFD │ │ROM_TR_DOS │ │ │ #1FFD │ │ROM_SYSTEM │ │ └---------┘ │RAM_0000 │ │ │RAM_4000, 8000│ │ └------┬-------┘ │ │ │ ┌------┴-------┐ ┌----┴---┐ ┌-----------┐ │ ПЗУ СТРАНИЦЫ │ │ПОРТЫ │ │ RAM_0 │ │ ПО 16 К │ │#7FFD ├--┤ ......... │ │ EXPANSION │ │#1FFD │ │ RAM_F │ │ TR-DOS │ └--------┘ │ │ │ BASIC 128 │ └-----┬-----┘ │ BASIC 48 │ ┌-----------┤ │ SYSTEM ROM │ │ │ │ SYSTEM ROM 2│ │ ┌-------┴------┐│ CONFIG 2 │ │ │ RAM_0 ││ CONFIG 1 │ │ │ ......... │└--------------┘ │ │ RAM__FF │ │ └--------------┘ │ └---------┐ │ ┌----------┐ ┌--┴----------┐ │ПОРТЫ КОМ-│ │ ISA_1 │ │ПЬЮТЕРА ├-┤ ISA_2 │ │ │ │ HDD │ └----------┘ │ OVER DEVICES│ └-------------┘Well, that's all for today, next time At least you can read the continuation of this we. ---═══---═══---════---════---═══---═══---
