I got the machine running today after playing around with the options parameters and correcting a few small mistakes with the cables. The wiring for the CD2 port is a hard to understand in the old manual but it is clear in the newer one. (posted below for those who may have the old manual)
Fortunately the machine was not sitting around it was making money running simple programs hand typed in. I could not justify the cost getting a tech to fix the RS232 but Fordav is right if I had more complex jobs lined up the repair would have been much faster. Although knowing what I now know I the option 1 card is definitely a good option, much better that soldering the main board and it would not have taken very long if I knew what I was doing. Now if the chips fry on the option card I can simply take it out card to replace them.
