------

I started with the pdf, using Preview in mac I selected regions and
|
|
copied and created new doc, saved it as jpeg and then used
|
|
the online OCR program: http://asv.aso.ecei.tohoku.ac.jp/tesseract/
|
|
I then manually edited each file.
|
|
|
|
The files are named according to the page index in the pdf and the
|
|
section and page given in the page footer. Page headers and footers
|
|
were not captured.

------------------
|
|
e00-01
|
|
- I used spaces to line up the comment columns, not tabs. I
|
|
picked the column distance arbitrarily.
|
|
- the bottom section looks like it could be tabbed but my tabstops
|
|
didnt line up with the values given so I used spaces
|
|
|
|
e00-02
|
|
- I used tabs for the start of each asm command but not for the
|
|
separation between mnemonic and arguments since these didnt line up.
|
|
with my tab stops.
|
|
|
|
e00-03
|
|
- left "dis addresses" typo in per original
|
|
|
|
e00-05
|
|
- cant tell if the "O" in quotes after 1: is a O or a 0.
|
|
- left mispelled "mormally" in comment
|
|
- left "file/etc/init" without space.
|
|
|
|
e00-06
|
|
- left mis-spacing on 5: move r5,r1.
|
|
|
|
e00-10
|
|
- left "/ect/init" typo
|
|
--------------------
|
|
e10-01
|
|
e10-02
|
|
- I used tabs for the first tab stop and spaced out to the next step.
|
|
- Per discussions with Brantley Coile it appears that the origianl
|
|
source probably used tabs, and that the printout has a tab stop
|
|
after 8 characters and another after 7 characters. The spaces
|
|
between opcode and operands are probably due to a tab, as can be
|
|
seen in later assembly code we have in machine readable form.
