So after some intensive transcribing work I finally got all files into source files ready for assembling using PAL11-S.
Assembling under PAL11-S rooted out a bunch of errors and then when side by side comparing the output listing with the PDF I found a bunch of more errors. The next step involved linking and during the first run a number of errors surfaced again. On the last run I only had two undefined: $ICO and $ICI. It makes sense since these two are part of the FPMP-11 package and used for number conversion. However adding the FPMP-11 object as an extra input in the link does not resolve these two undefined symbols. Does anyone have a clue on how to get a proper link with FPMP-11 for these two symbols? Here is the repo with PDF files, source PAL files, LST files and OBJ files as generated by PAL11-S: https://github.com/MattisLind/SPACEWAR /Mattis
