Introduction
AMSTRAD CPC6128
Integrated Computer/Disc System
A Logical Progression
AMSTRAD's hugely successful CPC464 and CPC664 systems have provided a sound
basis for further development, and now we proudly present the CPC6128.
In keeping with our policy of compatibility, the CPC6128 will operate with software
from both the CPC664 and CPC464 systems - but additionally provides a further 64K
bytes of RAM for use with CP/M and other user applications.
CP/MPlus
CP/M Plus (also known as CP/M 3.1) provides very easy access to the library ofCP/M
80 software. The 61K TPA means that any CP/M 80 program will find room to run,
and provide ample space for data. CP/M Plus is compatible with CP/M 2.2, although
we have provided both versions to ensure that applications developed using firmware
features in the AMSTRAD CP/M 2.2 systems will operate without modification.
CP/M Plus includes many enhancements that improve the performance of the
system, and most existing CP/M 2.2 software can take advantage of these facilities
without conflict. The CP/M Plus system incorporates a specific terminal emulation
feature whereby software that is configured to use screen handling characteristics
_similaLto_VT52and.Zenith-Z19/Z29-terminals-can-be installed-without· further
customisation.
GSX
The Graphics Extension System supplied with this version of CP/M Plus enables
applications programs to address printers/plotters and the screen using standard
instructions that extend the concept of CP/M program portability beyond the text
screen. Software that takes advantage of GSX will be able to be interfaced with a
number of graphics devices to provide hard copy of graphs, diagrams etc.
Dr. LOGO
Digital Research's LOGO continues to make inroads into computer education - and
the increased memory of the 6128 has permitted extensions to the Dr. LOGO first
used under CP/M 2.2. Programs will of course be upwards compatible from
AMSTRAD CP/M 2.2.
