For digital values, you can use a parallel port card, or even
handshake lines on a serial port.
For analog, you can again use a parallel port, and hook up an external
A/D chip. As long as you're not trying to get too many bits of
resolution this method works well (like say 8-bits). There are a lot
of chips out there that have many input pins for A/D. You select
ahead of time which input you want to take a sample on.
You might also try looking in Nuts and Volts magazine for cheap
PCI/ISA cards. That's a reasonably good place to find such things.

| I know this question does not really relate to the handyboard, but does anyone know of a cheap PCI or ISA card for a PC to read analog or digital values? Thanks, Mike Reiling (25 years ago, 3-Feb-00, to lugnet.robotics.handyboard)
