This would be so, for example, in outdoor or dirty environments or when you simply wish to check the status of one or two system parameters without the bother of hooking up a TV or monitor. One fairly easy and inexpensive way to do this is to use seven-segment LED (light-emitting diode) displays as your system output. Your ZX/TS bus doesn’t have enough power in reserve to directly drive these displays, but a few simple IC’s and an I/O board can give you this capability.
