I have a couple of older M7261, Etch C Rev F boards. Chips have dates codes in the late 71 - early 72 range so it is a quite early 11/05. The machine is completely dead with this board installed. The problem is that these boards differs quite a lot from later etches so the existing schematic are useless. The ones one bitsavers.org and the physical ones I have are all later revs.
Does anyone have schematic for the older C etch?
