Gary Mokotoff sent me a listing of 1401-FO-050, the Fortran II compiler,
versions v3m0 and v3m4.  I've finished "keypunching" and "proofreading"
it.  I already have operational tapes for v3m0 and v3m4, which (IIRC) I
found at Paul Pierce's web site.  I "proofread" my results by
disassembling the program overlay blocks of the tape, disassembling the
object "deck" resulting from assembling my work, and comparing them.
The relocatable libraries are card images on the operational tapes.  I
compared these with the object "deck" resulting from my work.  I had to
proofread the utilities by eye.  I did this by comparing the generated
code on my listing with the generated code on Gary's listing, line by
line, twice.  In a few cases, Gary took advantage of quirks in Autocoder
that are contrary to the manual (e.g. LTORG in INCLUDE).  I worked
around these to get the same assembled results using my Autocoder.

There might be differences in spacing, or typos, in the comments,
compared to the original listings; I can't check these automagically.

The encoding in the files is Pierce A (see attached code chart).

All these results are attached in the file Mokotoff.zip.

Gary also sent notes and flowcharts, with which I've done nothing so
far.  I plan to transcribe the notes, and I might re-create the
flowcharts using a drawing program (probably tgif).

Al:  Do you want to scan, and maybe OCR, the listings, notes,
flowcharts...?  They're all loose-leaf.
