Blackface ADAT schematic?

Last night I had mine open probing around with a dvm trying to find out what signal line might go high or low when put in record mode.

I touched a test point that said 5V and when I did I saw 5v on the dvm with respect to chassis ground but the tape I had in it ejected and now she wont take a tape when you try to put one in.

I have broken my remote recorder and need a schematic or service manual.

Thanks,
