3900-3bff unused - kbd mirrored
3c00-3fff video RAM R/W D0-D5,D7 (or D0-D7)
4000-ffff RAM
Interrupts:
IRQ mode 1
NMI
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
