A simple 8bit Input port from Maplin. Intended (among others) for use with the Maplins Weather Satellite Receiver.
Technical
Can be mapped to Port F8F0h..F8FFh (jumper select-able). F8F0h (with a mirror at F8F1h) can be considered as default (this address is also recommended as 8bit-input address in the Weather Satellite source code).
Note that the original article specifes addresses F8E0h..F8EFh instead of F8F0h..F8FFh - that is wrong, the schematic connects A4 to EN1, so ports are accessed when Address Bit4=1.
