The Velleman K-8000 I/O card is supplied as a kit, it took me about 4 hours to solder all the components to place.
The card has 8 low res analogue outports (6 bit) and 1 high
res analogue outport (8 bit)
4 analogue (8 bit) inports and 16 digital ports whish can be configured as in or
outports.
It's possible to connect up to 3 K-8000 cards i serie that gives 27 analogue outports, 12 analogue inports and 48 digital I/O, the card connects to the printer port, and supports programs written in C, VB and Turbo Pascal.
