Dust off that old GPIB hardware and hook it up to your modern computing platform using either of these two solutions. If you haven’t a clue what we’re talking about you probably don’t own any fifty-year-old test equipment. But the General Purpose Interface Bus (aka IEEE-488) was fairly common on 1960’s era test equipment like multimeters and logic analyzers.
To the lower right is a USB to GPIB converter board that [Steven Casagrande] developed. This one is PIC based, using the 18F4520 and an FTDI chip to handle the USB side of the equation.
Check out the connector that is used for this protocol. We’d bet that’s not the easiest part to source. But at least now you’ll know what you’re looking at when pawing through the flea market offerings.
