They licensed it from TI, who developed it while exploring the wonders of Lisp. Anyone here remember the Lisp Machines that were extremely popular once? Oh yes, I have several of them here, all Symbolics. A 3640, 3645, and an XL1201. One was made by TI. And it used that expansion bus. Yes, the TI Explorer. I hadn't remembered that that was where NuBus came from. Neat. Then it's less of a happenstance thing that Cisco used it, given their Lisp connections back then. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
