Looking for assistance PDP 11/05 Console I/O

The serial port on one of the CPU boards uses the standard console port addresses, so if youset another DL11 to the same address then there's a conflcit. You can use a DL11 at a differnet address, of course, but standard OSes will not use it as the console. On the later 11/05 CPU boards (which I don;t think yours are, but you'll have to check the printset) there is a soldered jumper you can fit to disable the internal console port.. At which point you can use a DL11. But there is nothinglike that on the original CPU boards. What I can't rememebr is if the PDP11/05 also ahs the TTL-level serial lines on the connecotr (I know it doesn't have RS232 ones). if it does, then it's asimple job to link up a MAX232 or similar. The other option is to build a current loop conerter. It's not that difficult... -tony
