reZet80 PIONEER - 6-digit 7-segment LED display

This is the 6-digit display card for the DISPLAY bus (see 6-digit TIL311 display for the specs).
It displays 6 hexadecimal numbers with 7-segment LED displays.
Please note that the decimal point is wired in hardware but not enabled in software in the current version.
The card uses one I/O port in the 8-bit I/O space (see specs for I/O map and decoding).

The card has been designed for 7mm common cathode LED displays.
Provisions have been made to accomodate all LED displays up to a height of 17,78 mm (distance between pins) but you'll have to wire them yourself on the card.
It's also possible to use common anode displays but hardware and software need to be adapted.
