New page

The [[Schneiderware Uni-PIO]] is a general purpose I/O port with 48 input/output signals, published by german magazine [[CPC Schneider International]] as part of their [[Schneiderware]] DIY series. The plain PCB, or the fully assembled board were also available via mail-order.

The [[ECB Bus]] connector of the board is intended to be plugged into the [[Schneiderware Basisplatine]], but it could be also wired directly to the CPCs Expansion Port.

== I/O Ports ==

Default I/O Addresses are F8E8h-F8EFh, optionally a second or third Uni-PIO card can be jumpered to F8F0h-F8F7h and F8F8h-F8F8h, giving a total of 144 I/O lines when using three cards.

{|{{Prettytable|width: 700px; font-size: 2em;}}
|Address (default) || Address (alternate) || Usage
|-
|F8E8h || F8F0h,F8F8h || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port A ('''without''' pull-ups, with red LEDs)
|-
|F8E9h || F8F1h,F8F9h || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port B ('''with''' pull-ups and green LEDs)
|-
|F8EAh || F8F2h,F8FAh || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Port C (lower 4bit '''without''' pull-ups and red LEDs, upper 4bit '''with''' pull-ups and green LEDs)
|-
|F8EBh || F8F3h,F8FBh || Schneiderware Uni-PIO [[8255 PPI chip]] #1 Control
|-
|F8ECh || F8F4h,F8FCh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port A (without pull-ups or LEDs)
|-
|F8EDh || F8F5h,F8FDh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port B (without pull-ups or LEDs)
|-
|F8EEh || F8F6h,F8FEh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Port C (without pull-ups or LEDs)
|-
|F8EFh || F8F7h,F8FFh || Schneiderware Uni-PIO [[8255 PPI chip]] #2 Control
|-
|}

'''Cautions''' - Port F8F0h-F8F3h were also used as alternate address of the [[Schneiderware Centronics Port]], recommended work-around is to modify the Centronics card. On the PCBs, two PPI #1 Port C signals are accidently exchanged with each other (wired to the wrong pins on the 50-pin connector, and to the wrong LEDs).
