Configure hardware → ICS Advent (82C55A) I/O hardware
You may have up to 8 ICS Advent cards (82C55A chips). For each card, set the card's I/O base address, and choose which ports are to be used as inputs and which as outputs. You can also choose whether to reverse the logic of the card's inputs and/or outputs. Changes will not take effect until you restart the WhiskerServer program.
This hardware is supported as it was/is used by the original Monkey CANTAB system (supplied by Cambridge Cognition Ltd). The original Monkey CANTAB was a DOS-based program that expects a single 82C55A chip at I/O address 0x300.
For details of I/O address assignment and why this is a dangerous card, see
