-
-Interrupts:
-IRQ mode 1
-NMI
-
-Printer: Level II usually 37e8; System80 uses port FD.
-
-System80 has non-addressable dip switches to set the UART control register.
-System80 has non-addressable links to set the baud rate. Receive and Transmit clocks are tied together.
-
-Cassette baud rates: Model I level I - 250 baud
- Model I level II and all clones - 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
-
-FE:
-- bit 4 selects internal cassette player (low) or external unit (high) on a system-80
-
-FD:
-- Read printer status on a system-80
-- Write to printer on a system-80
-
-F9:
-- UART data (write) status (read) on a system-80
-
-F8:
-- UART data (read) status (write) on a system-80
-
-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 system80 - Asian version of trs80l2, known as EACA Video Genie. In USA called
- PMC-80, in South Africa called TRZ-80, and Dick Smith imported them to Australia and
- New Zealand as the System 80. The Hungarian version is the ht1080z.
- Inbuilt extensions:
- - SYSTEM then /12288 = enable extended keyboard and flashing block cursor
- - SYSTEM then /12299 = turn cursor back to normal
- - SYSTEM then /12294 = enable extended keyboard only
- - SYSTEM then /12710 = enter machine-language monitor
- Monitor commands:
- - B : return to Basic
- - Dnnnn : Dump hex to screen. Press down-arrow for more. Press enter to quit.
- - Mnnnn : Modify memory. Enter new byte and it increments to next address. X to quit.
- - Gnnnn : Execute program at nnnn
- - Gnnnn,tttt : as above, breakpoint at tttt
- - R : modify registers
- The monitor works on the radionic too.
-
-About the ht1080z - This was made for schools in Hungary. Each comes with a BASIC extension roms
- which activated Hungarian features. To activate - start emulation - enter SYSTEM
- Enter /12288 and the extensions will be installed and you are returned to READY.
- The ht1080z is identical to the System 80, apart from the character rom.
- The ht1080z2 has a modified extension rom and character generator.
-
-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.
-
-Not dumped (to our knowledge):
- TRS80 Japanese bios
- TRS80 Katakana Character Generator
- TRS80 Small English Character Generator
- TRS80 Model III old version Character Generator
- TRS80 Model II bios and boot disk
-
-Not emulated:
- TRS80 Japanese kana/ascii switch and alternate keyboard
- TRS80 Model III/4 Hard drive, Graphics board, Alternate Character set
- Radionic has 16 colours with a byte at 350B controlling the operation. See manual.
-
-Virtual floppy disk formats are JV1, JV3, and DMK. JV3 is not emulated.
-
-********************************************************************************************************
-
-To Do / Status:
---------------
-
-For those machines that allow it, add cass2 as an image device and hook it up.
-
-trs80: works
-
-trs80l2: works
- expansion-box to be slotified
-
-sys80: works
- investigate expansion-box
- add 32 / 64 cpl switch
-
-ht1080z works
- verify clock for AY-3-8910
- investigate expansion-box
-
-radionic: works
- floppy not working (@6C0, DRQ never gets set)
- add colour
- expansion-box?
- uart
-
-
-General Issues:
- Most machines have problems loading real tapes.
- MAME will crash if you try to create a JV1 disk.
- All known images are the JV1 format, therefore
- the support for other formats has been removed.
