+Printer: Level II usually 37e8
+
+Cassette baud rate: 500 baud
+
+I/O ports
+FF:
+- bits 0 and 1 are for writing a cassette
+- bit 2 must be high to turn the cassette motor on, enables cassette data paths on a system-80
+- bit 3 switches the display between 64 or 32 characters per line
+- bit 6 remembers the 32/64 screen mode (inverted)
+- bit 7 is for reading from a cassette
+
+Shift and Right-arrow will enable 32 cpl, if the hardware allows it.
+
+SYSTEM commands:
+ - Press Break (End key) to quit
+ - Press Enter to exit with error
+ - xxxx to load program xxxx from tape.
+ - / to execute last program loaded
+ - /nnnnn to execute program at nnnnn (decimal)
+
+About the RTC - The time is incremented while ever the cursor is flashing. It is stored in a series
+ of bytes in the computer's work area. The bytes are in a certain order, this is:
+ seconds, minutes, hours, year, day, month. The seconds are stored at 0x4041.
+ A reboot always sets the time to zero.
+
+Radionic has 16 colours with a byte at 350B controlling the operation. See manual.
+
+
+********************************************************************************************************
+
+To Do / Status:
+--------------
+
+- For those machines that allow it, add cass2 as an image device and hook it up.
+- Difficulty loading real tapes.
+- Writing to floppy is problematic; freezing/crashing are common issues.
+
+radionic: works
+ floppy not working (@6C0, DRQ never gets set)
+ add colour
+ expansion-box?
+ uart
