Uses I/O ports: [[I/O_Port_Summary|#1C00]] and [[I/O_Port_Summary|#1F00]] (as shown in above BASIC example) (and as on page 1-26 and 1-27 of the original manual)
* #1C00 and #1F00 are bad decodings/mirrors of [[CRTC]] ports #BC00 and #BF00
* These ports will clash with other hardware (but do work more or less)
