Unusual ISA GPIB Board: ID?

[KC7GR]

Good day,

I've come across an oddball GPIB ISA bus card. It's most definitely NI, from the AT-GPIB family, but I've never seen one of those boards have a pair of RCA phono jacks near the backside. As if that wasn't weird enough, there's two additional chips, made by Fujitsu, attached near said jacks.

I've found a part number label on it marked 182785E-01, but nothing relevant seems to come up for that number when searching NI support.

I'm sure it's usable as a stock AT-GPIB, but I'm curious to know what its intended application was.

Thanks much.

That's an old "AT-GPIB TNT +"

The Fujitsu -701's are pnp ISA Controllers I believe there are two to support 16 bit data.  I forget which handshake lines were exposed on the jacks.

Not really useful to know since it needs a 16 bit OS

Thank you. And I wouldn't say entirely useless. There are things which still work best with ISA-based cards (yes, I know I'm risking a holy war, saying stuff like that... Sheesh, you'd think it's the 'vi' or 'emacs' battle all over again). 😉

Keep the peace(es).
