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.
