This board adds a parallel port and two serial (RS232) ports to computers with a free ISA slot. The schematics of this board is heavily inspired by the parallel port schematics found in the IBM 5150 ...

In EEG/ERP studies it is common to send triggers to mark the timestamp for significant events (e.g., the onset of a trial, presentation of a particular stimulus, etc.). Triggers are typically bytes ...

How do I do this? I can't seem to find a piece of hardware that will emulate a proper Parallel port over USB, they all use "USB Printing Support". But im not trying to hook up a printer. I need it for ...

I have a PC-based DSO that connects via parallel port that I'd like to get working via USB (preferable) or at least ExpressCard. I picked up a USB-parallel adapter from MicroCenter thinking it would ...

If your small business is typical, you want to get the longest lifespan possible from your tech investment, and therefore you may have an older dot-matrix or laser printer with a parallel port that ...

With the continuing manufacture of new computers, there is a clear and obvious trend of the parallel port becoming less and less common. For our younger readers; the parallel port is an interface ...

Many laser printers last for years, so businesses often keep older laser printers around even after upgrading other hardware. Many older laser printers use a parallel port interface rather than the ...
