When a byte is received over serial, the individual bits are set on the individual digital lines connected to the printer’s parallel port. At this point, the strobe line is pulled low ...

Old Macs used the serial port for printers. Also known as an RS-232 port, serial ports provide very slow speeds and have been superseded by USB on desktop computers. USB-to-serial adapters are ...

This is very old project from year(s) ago. This project was created to test current top Anti-Cheats against FPGA approach with minimal effort / knowledge with maximal success. At his peak, count at ...

The I/O bus from the CPU to the peripherals is a parallel bus (16, 32 or 64 wires, etc.). Although sounding similar, a serial bus differs from a serial port. Both use serial transmission ...

For his Hackaday Prize entry, [serdef] is bringing the sound of the 80s to the parallel port with the OPL2LPT. It’s a sound card for the parallel port that isn’t just a resistor DAC like the ...
