BASIC for the HBC-56

Here is a "port" of 6502 EhBASIC for the HBC-56. It includes a keyboard input driver and three output drivers:

  • TMS9918
  • Character LCD
  • Graphics LCD

Building and running

To run in the emulator (TMS9918 version) using MAKE:

cd code\6502\basic
make

BASIC

To build and run manually:

cd code\6502\basic
..\..\..\tools\acme\bin\acme -I ..\lib -I ..\kernel -o basic_tms.o -l basic_tms.o.lmap basic_tms.asm
..\..\..\emulator\bin\Hbc56Emu.exe --rom basic_tms.o

Versions / drivers

There are two main asm files which jsut include the various components required for each build:

  • basic_tms.asm - the TMS9918 verion
  • basic_lcd.asm - the LCD version

The LCD version has two possible output drivers. One for a standard character LCD and another for a graphics LCD:
