THE 2X INTERFACE 1.. .
incorporates the three functions of Microdrive controller, local area network
and RS232 Interface. Connect it to your Spectrum and you can control up
to eight Microdrives, communicate with other computers and drive a wide
range of printers.
THE 2X MICRODRIVE.. .
gives you fast Access to a large memory. Each Microdrive can hold up to
100K bytes using a single interchangeable cartridge.
THIS MANUAL . . .
introduces the idea of using BASIC as an
operating system as well as a
programming
language. This way, BASIC can be used to set up
communication links, to send and receive data along them and to manipulate
files. This adds enormously to its power to perform tasks in which:
- data is stored and retrieved,
- data and programs are sent to peripherals,
- communication links are established with other Spectrum computers or
with other types of computer.
The combined use of BASIC as an operating system and a programming
language gives it a power and flexibility, and also an ease of use, to be
found in few larger computers.
You should read the chapters on the Microdrive even if you have not bought
one, since they introduce various concepts (about
channels
and .Weams and
their use) which you will need to understand.
This manual should only be read
after
you have familiarised yourself with the
ZX Spectrum Introduction booklet and with chapters 1 to 22 of the BASIC
programming manual.
