The advantage of the PCT board is it's lower cost when working with smaller, mature program code. Many of these are accessible on the PCT board. The HC11 is operated in single-chip mode. The HC11E series and HC11F1 are very similar in structure from a programming point of view. To develop program code for a single-chip HC11, you will need a way of simulating or emulating the chip.
Windowed chips are available that can be erased under a powerful ultraviolet light.
These support re-programming without the lengthy ultraviolet erase cycle. There are a number of suppliers of assemblers, compilers, simulators and emulators. Many of these are suitable for large project development, but not cost effective for small projects or for hobby or classroom experimentation. The EVBU is very simple and of limited use due to its lack of available memory. The EVB is an excellent tool for single chip development.
