LCD board
This board allows a HD44780 based LCD such as this one to display data from the computer.
The LCD is enabled by default in the ROM file. Due to the delays it requires, it significantly slows the output. If you are only using the computer over serial, you can disable printing to the LCD by setting a zero in the location pointed to by the haslcd
word, for example like this:
0 haslcd c!
Slot placement
The LCD board should be inserted in SLOT 4 on the backplane, otherwise you will have to change the hardware definitions in lcd.inc
