I thought I'd document this for anyone who is interested in Beeb hardware.This is my original ROM board from my first BBC Micro (Model B). It was removed prior to trading in the Model B at Watford Electronics, so I could afford a Master 512.
This is an Issue 2 board, the layout is a little different to the images of the original board I've seen elsewhere on the internet, the obvious change being the slightly slanted ROM sockets.
Peartree also updated(?) the silk screen to identify on the board where the jumper connection and spring clip wire attach on the main circuit board.
Since the box and instructions suffered from the dreaded damp and subsequent mold, that's a definite help and you have to wonder why this wasn't general practice.
I'll add images of the manual, but they look broadly similar to the instructions others have already posted (aside from their horrible condition). Luckily most of the printed sections are OK, it's mostly the page edges that were destroyed.
