TTY console mode
Press the TTY console switch to let the KIM simulator use a glass teletype in a console window. The standard KIM user interface is shown, see the manual how to use.
Note: set the PC keyboard to CAPS Lock, only uppercase is used in the KIM monitor.
Note the menu options to record a session, (Load Text to Console) or play (Save text from Console, followed by Stop saving text ) a text file in the console.
This is in fact the same functionality as a teletype with high speed papertape punch or reader. You can use this to load and save Basic programs as ASCII text files. Or use the KIM-1 tape routines built in KB9 Basic!
The console
The console is an emulation video terminal (ANSI color, subset) connected to an ACIA (a Motorola 6850) in the KIM-1. The KIM Monitor is patched to send or receive via the ACIA and is transparant to the user of the KIM-1 I/O routines (even the quirks like flags and returned register values!)
Keyboard input, when the console window has focus, is sent to the serial input of the ACIA. No local echo. The KIM-1 monitor only accepts uppercase (hint: Caps lock!), user programs are free to use upper or lowercase.
Characters sent tot to ACIA output are received by the console window and handled as a VT100 would do, a subset of the ANSI/VT100 is implemented.
All keys of the PC are usable, SHIFT works. Note the translation of codes from the PC keyboard to ASCII characters is for the keybaord choosen in Settings.
Other mappings are possible by changing the routine in console.pas: procedure TFconsole.FormKeyDown
Received characters by the console are handled as follows, a subset of the ANSI set.
