Hello! I went back to that same Wikipedia page, cf. http://en.wikipedia.org/wiki/PDP-11 and making my way further down and after the PDT-11 family I found that crowd: SBC 11/21 (boardname KXT11) Falcon and Falcon Plus single board computer on a Qbus card implementing the basic PDP-11 instruction set, based on T11 chipset containing 32 KB static RAM, two ROM sockets, three serial lines, 20 bit parallel I/O, three interval timers and a two-channel DMA controller. Up to 14 Falcons could be placed into one Qbus system. KXJ11 QBUS card (M7616) with PDP-11 based peripheral processor and DMA controller. Based on a J11 CPU equipped with 512 kB RAM, 64 kB ROM and parallel and serial interfaces. What I am thinking of is taking one of each and putting them into a card cage. Of course the other issue that's, ah, fuzzy at best, is finding them. The page also shows individual processors, the F-11 or the J-11 ones. Again group I am only thinking here. The incredibly big problem is still the obvious, that of finding them, and then a card cage. And no I've not even got a basket of clews here to explain where I am going with this one. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."
