I just got my hands on an FPF11 board, and naturally I want to connect it to my 11/23+ right away! I understand that the 40 pin header on the card edge connects to a 40 pin DIP plug that goes into one of the microcode option sockets on the 11/23+. Dumb question #1 - is it conventional to install the FPF11 in the slot immediately below the CPU, thus displacing all the memory boards down a slot? Or does the FPF11 go in the first Q/Q slot (slot 4) ? Or does it even matter? Dumb question #2 - the handbook says, "[the FPF11] ... complements the KEF11-AA". Does this mean that the FIS option chip must _also_ be installed in the 11/23+? Or must it _not_ be installed? Dumb question #3 - does it matter which one of the microcode option sockets you plug the FPF11 into? And... #4 - how do you know if the thing's working? Short of having the diagnostics for it, of course, which I don't. Thanks, Bob Armstrong
