|
||||
|
||||
Skeleton driver for Facit 4440 Twist terminal.
|
||||
|
||||
The “Twist” sobriquet refers to the adjustable orientation of the
|
||||
monitor, whose normally black-on-white display has the dimensions of a
|
||||
sheet of A4 paper. It displays 24 lines of 80 characters in landscape
|
||||
mode and 72 lines of rather smaller characters in portrait mode.
|
||||
|
||||
No user manual for this terminal has been found. The layout of the
|
||||
keyboard is also unclear, not to mention the serial protocol.
|
||||
|
||||
Nonvolatile settings are configured through VT100-style setup screens.
|
||||
Several non-ANSI emulation modes are also available.
|
||||
|
||||
An OEM customized version was sold by Norsk Data AS as the ND 319 Twist.
|
||||
|
||||
The timing of the display circuit seems a bit uncertain. Promotional
|
||||
information claims that it has a 40 MHz bandwidth, but this may be only
|
||||
a nominal maximum rating since the only high-frequency oscillator seen
|
||||
on the PCB is 32 MHz. It is unclear how the CRTC parameters and this
|
||||
value can produce the documented 65 Hz refresh rate. The actual circuit
|
||||
also generates alarming levels of electromagnetic radiation.

||||
