" ... keyed in the source for Autocoder ..."
I have SPS-2 and SSPS (Ralph Reinke gave them to Paul Pierce but I can't find them at Pierce's web today). If the offer is for SPS-2 or SSPS, their only incremental value would be the cards themselves. I haven't seen SPS-1 or RPG before, so if that's what's offered, it would be worth getting.
I also have two core dump routines (One from Ralph Reinke and one from Germany, both at Paul Pierce's web), an Autocoder distribution deck (from Dick Weaver), a machine-exercise demo (from HzG), two tape I/O packages I wrote in 1966-67, several application programs from Dick Weaver, and several programs (mostly "system" programs) from Florida State University (Rich Ragan gave a tape to Al Kossow, who lent it to Paul Pierce, who posted the contents), including two-tape Autocoder (by R. B. Rosenberger).
I've keyed in the source for Autocoder from the listing in the CE manual Dick Weaver lent me, together with eleven update letters and a custom modification by A. B. Platt that prints A- and B- address fields in decimal as well as machine form.
I assume we can turn these back into cards when the PC-to-1401 interface is operative. I also have the operational Autocoder tape that includes IOCS, Fortran v3m0, and Fortran v3m4 from Paul Pierce's web. I assume we can turn these back into tapes when the PC-to-1401 interface is operative.
I also have a listing for two-tape Autocoder from Paul Pierce's web, and a listing of a program by Ken Dritz to punch core into a self-loading deck.
I probably have programs not listed here. Someday I should do a systematic inventory of the 1401 software I have.-- Van Snyder | What fraction of Americans believe Van.Snyder@jpl.nasa.gov | Wrestling is real and NASA is fake?

I've also located and spoken with Ralph Mork, 90! He's living in Wilmington, NC and is cc'd on this email (via Gary Paige). He was just delighted that we're interested in his early history/stories. Ralph worked with the WWAM team and pulled together the 3-person design group in Endicott to explore using core memory for program store (instead of the WWAM's plugboard).
I've also located and spoken with Chuck Branscomb, 80! He's living in Carey, NC and is cc'd on this email. He was the overall 1401 program manager, responsible for the overall program of getting the 1401 designed and transferred to test & manufacturing, documentation, etc (all in record time). Jim reported to Chuck.
Jonie Dayger managed the 1403, but is deceased. Russ Rowley is also deceased.

Utility - sort, compiliers, assembler, ... - from Van Snyder, Feb 2010
An "original 1401 binary" that uses the card reader, tapes, and printer (and the card punch if you want it to), and therefore is a reasonable demo, is the Autocoder assembler.
The that tapes that I understand were part of the Connecticut computer acquisition included operational Autocoder tapes.
A list of the tapes, and what I've determined to be on them, is attached. The list uses Paul Pierce's accession numbers.
I have SimH-format copies of them all, in case you want to access them by way of the 729 emulator.
adc00223_COBOL File 1 is an operational COBOL compiler. File 2 is a program that extracts a listing and a deck of Autocoder macros. File 4 is a LIB identification card. File 5 is a PID identification card. adc00224-SORT7 This is a distribution tape. The first record of the first file is a program that prints a listing and punches an operational deck. File 2 is a LIB identification card. File 3 is a PID identification card. adc00225-KWIC This is a distribution tape. File 1 is a program that prints, punches or copies other files. File 2 is an object deck and test decks. File 3 is a source deck. File 4 is a LIB identification card. File 5 is a PID identification card. adc00226-AUTOCODER This is a distribution tape. File 1 is a program that prints the listing and/or punches the installation deck. File 2, up to ]]]]], is the listing; then the installation deck. File 3 is a LIB identification card. File 4 is a PID identification card. adc00227-SE12x The first file of this tape is an operational program. It appears that files 2-5 are a sample problem, a source deck, sample output, and a source listing. adc00228-FI-04X This is a distribution tape. File 1 is an operational program. File 2 is a source deck. File 3 is a listing. File 4 is a LIB identification card. File 5 is a PID identification card. adc00229-SE-12X This is a distribution tape. File 1 is an object deck that clears core down to 900. File 2 is an object deck that is preceded by some special cards that write some data on tape 6 in odd parity. The remainder of the deck has PHS-1 in 76-80. File 3 is an object deck that has PHS-2 in 76-80. File 4 is an object deck that has PHS-3 in 76-80. Files 5-8 are source decks for files 1-4, except for the special cards that precede file 2. File 9 is a LIB identification card. File 10 is a PID identification card. adc00231-SORT7 This is a distribution tape. The first record of file 1 is a program that unblocks, prints, and punches the remainder of the first file, which is an assembly listing and source deck. File 2 is a LIB identification card. File 3 is a PID identification card. adc00232-AUTOCODER This is an operational Autocoder tape with numerous macros. adc00233-Fortran-IV-FO-052 This is a distribution tape. See pages 73-77 of C24-3322-2. File 1 is the distribution. File 2 is a LIB identification card. File 3 is a PID identification card. adc00234-MERGE7.dmp This is a distribition tape. The first record of file 1 is a progam that unblocks, prints, and punches the remainder of the first file, which is an assembly listing and source deck. File 2 is a LIB identification card. File 3 is a PID identification card. adc00236-SORT7 This is an operational tape. The first two records are a program that is used to create, update or copy the remainder of the tape. File 1 is the operational program. File 2 is a copy of the last 17 records from file 1. It looks like the tape was re-written with a shorter program after having been written with a longer program. The tape is slightly corrupted, in that the first two records actually should be a single record. adc00237-IOCS This is a distribution tape. The first record is a program that unblocks, prints, and punches the remainder of the first file. File 1 is the distribution. File 2 is a PID identification card. adc00238-DFTS This is an operational diagnostics tape. adc00239-AUTOCODER+macros This is an operational Autocoder tape with numerous macros. adc00240-CLUB_PROG This appears to be an operational tape for an application program for the Innis Arden Golf Club. adc00244-AUTOCODER-mod_by_OK_data This is an operational Autocoder tape with numerous macros. adc00249-SORT7 appears to be a corrupt copy of adc00236-SORT7 adc00250-Fortran-IV-FO-052 This is an operational Fortran IV compiler tape.
