Ok, I lied.  Only MAINDEC08_D5FA_PB_COPY2.BIN is broken.

./From_Vince_Slyngstad/maindec/maindec-08-d5fa-pb            ok, same as #3
./papertapeImages/set1/MAINDEC08_D5FA_PB_COPY2.BIN           bad
./papertapeImages/set8_20040316/tray1/maindec-08-d5fa-pb.bin ok, same as #1
./papertapeImages/set8_20040316/tray1/maindec-8i-d5fa-pb.bin ok, bigger 
than 1 & 3

Apparently maindec-8i-d5fa is not the same as maindec-08-d5fa-pb but it does
appear maindec-08-d5fa-pb is ok.

Any chance there is a hard copy of the source?  That would be very helpful.

sorry for the confusion.
