After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends ...

The 74AHC164 and 74AHCT164 are 8-bit serial-in/parallel-out shift registers and are classified as high speed silicon-gate CMOS devices. These devices are pin compatible with Low-power Schottky TTL ...

This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

After the new millennium, the channels between the computer and its peripheral devices have switched from parallel to serial data transfer. Although it would seem that a parallel cable with multiple ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...
