Description of computer ports
Sinclair Profi (Profi +)
(C) Penetrator (VFHB)
In recent years, there were many
quality software products that are used in all the upper memory,
but not many of them are completely bspolzuyut
upper memory computers such as Profi.
Therefore, read the full
description of the ports of the "monster".
Main peripherals
in a long address
WARNING! Long addressing is valid in all modes
the computer.
w - means that the port is only available for recording.
r - means that the port is read-only.
