[pups] pdp11/05 questions.

hi all, The recent flurry of activity in early pre-C UNIX for an 11 with a small memory got me back to working on my 11/05. So far I've identified two nasty problems with the data paths board, the M7260. One of the 8266 MUX chips looks like the plastic boiled and bubbled and circuit board is discolored underneath it. I'd welcome both sources for replacement chips and techniques for replacing it. Additionally there's a lifted and broken trace on the non-component side of the module near the F edge connector. Any sugestions for repairing a damaged trace would be welcome. Lastly, I'd just as soon use a DL11W in the 11/05 rather than go to the trouble of setting up an external clock to feed the on board UART. I can get both 9600 baud and RS232 from the DL11W instead of 2400 baud current loop from the built-in interface. I haven't yet found the jumpers to remove/install that would disable the built-in console interface. There's also the LTC.
