/***********************************************************************************************************************************
Skeleton driver for Wyse WY-150 and related terminals.
The WY-150, originally introduced in Nov. 1988, was the first of the "terminals of the future" that Wyse sold well into the
1990s. The WY-160 is a graphical terminal that runs on different but clearly related hardware.
All video functions in these terminals are integrated into ASICs (e.g. 211009-01, 211009-02). The 8032 generates all active
signals for both the main serial port and the serial keyboard. Three 8Kx8 SRAMs are used to store characters, attributes and
font data; the second is also battery-backed.
