Description
The SonyLDP BASIC is an extension that comes with the Sony HB-G900 series of computers.
Most of the provided instructions allow to control a LaserDisc using the built-in the RS-232C interface, but a few instructions are useful to show large texts on the screen with the superimposing feature of these machines.
Instructions
This extension adds 23 new instructions, that can be generally divided into four types of functions.
See http://www.msxarchive.nl/pub/msx/docs/hwmodsetc/hanso/userguides/sonyhbg900pvideoug.pdf for the full guide.
Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.
