And interestingly, if you wanted to use the TI bus driver chips, they're still available and inexpensive (<$3) I'm not getting new GPIB gear any time soon, but the idea of a WiFi/GPIB that pulls power from the host instrument is intriguing. At work, we build up racks of gear to test spacecraft and various systems, and I've spent way too many hours in days gone by trying to get just the right cabling to get it to reliably work. The Prologix units are great, Ethernet cables are easier to manage than those shielded GPIB cables - and there's galvanic isolation inherent in the Ethernet. But all those wall warts (still, easier to manage than GPIB cables). I'm going to pass this on to some of the folks who put together these systems.

I actually did much the same to use my ancient HP and TI gear, and turned it into a commercial product. My KISS-488 is listed on eBay and Amazon (though not much longer on Amazon, as sales via Amazon have been really slow). Just a standard GPIB plug with an Ethernet jack on the back. If it suits your purpose, I can offer a discount by selling it directly rather than thru eBay. There's a wonderful YouTube video review of it by an independent party (no, I didn't pay him to do that!). You can see it at www.hxengineering.com. My direct email is SteveHx@HxEngineering.com.
