Chris Torrence Is the "Roger Wagner Volunteer Archivist"

The Softalk Apple Project is very pleased to announce that Chris Torrence has accepted the role of Roger Wagner Volunteer Archivist for the Softalk Apple Project. Chris brings to the project a long standing appreciation for Softalk magazine and particularly for the articles written by Roger Wagner on Assembly Language. As Chris stated in accepting this Volunteer Archivist role:

I received my first complimentary issue of Softalk in January 1982, a couple of months after my family had won an Apple II+ at a computer store grand opening in Detroit, Michigan. I was 13 years old and in 8th grade, and from that point on, I was hooked on computers. I remember pouring over each issue of Softalk, reading reviews of new games, and interviews with people like Buckminster Fuller and Richard Bach.

One of the best sections was called "Assembly Lines", written by Roger Wagner. Here was someone who could explain the arcane mysteries of 6502 assembly language programming with both humor and passion. By January 1982, Assembly Lines was already up to part 16, past the "simple" stuff, and well into sound generation and hi-res graphics routines. A few months later, Softalk Books published a collection of the first 15 articles in Assembly Lines: The Book. The magazine series continued until June 1983. Softalk Publishing promised that Volume 2 would soon be arriving, containing all of the remaining articles. Alas, Softalk Publishing went bankrupt before the second volume could be completed.

Now, with Roger Wagner's blessing, I have taken on the task of publishing a combined book containing all of the content of Assembly Lines: The Book, as well as the remaining Softalk articles. As part of this task, I have also taken on the role of Volunteer Archivist on the Softalk Archive for all of Roger Wagner's contributions to Softalk magazine. Roger Wagner, in addition to his "Assembly Lines" series, was also the owner and president of Southwestern Data Systems (SDS) and later, Roger Wagner Publishing. Roger's companies published software such as the Merlin Macro Assembler, The Correspondent, Apple-Doc and List Master, ASCII Express and Z-Term, as well as many others.

As the Roger Wagner Volunteer Archivist, my goal will be to gather all references to Roger Wagner and SDS within Softalk, cross reference and link these with other references on the web using Linked Open Data (LOD), and hopefully, tie these references in a meaningful way to the rest of the Softalk archive. But I don't want this to just be a one-man show. If you find additional references to Roger Wagner, "Assembly Lines", or Southwestern Data Systems, please contact me and I'll make sure they get added to the archive.

Welcome aboard Chris! You've earned 300+ FactMiners pre-launch points as our first FactMiners/STAP Volunteer Archivist.

Hard at work

I'm currently up to Chapter 9 ("The Stack") in Assembly Lines: The New Book. You can read the original issue #1 of Assembly Lines over at: http://www.softalkapple.com/content/assembly-lines-roger-wagner-no-1-oct...

As described there, the goal is to publish a book containing all of the content of Volume 1 plus all of the remaining articles from Softalk that were supposed to have been in Volume 2.

More to follow...

Assembly Lines The Book Version 2.0

This inquiry is to Mr. Torrance and the rest of the Project Staff:

When the updated book is completed/done, does one have to go to Amazon
or any other (online) bookseller to "purchase" the book or will it be available
on this site without cost or obligation?

An old saying some may remember or heard of: "There is no free lunch"...

And another question: Does Roger Wagner get any compensation or royalties
since this is his (copyrighted) work, even though the publication (Softalk) in print
form is not available, but only the digital form (which the Project Team is busily
working on now)???

SL

Great questions!

Hi, these are both great questions.

First, the book will only be available in print form (via Amazon and Lulu), since Roger Wagner has not given his permission to release a PDF.

That being said, you can already read all of Assembly Lines Volume 1 on Open Library. And, you will also be able to download all of the original Softalk articles for free here on the website.

Regarding your other question, the plan (approved by Roger Wagner) is to price the book "at cost". No one will receive any compensation or royalties. Given a book of approximately 400 pages, the price will be around $10 for softcover and $20-$25 for hardcover.

Let me know if you have further questions. Also, if you have 6502 programming skills or proofreading skills, I might be looking for proofreaders!

To Mr. Torrence:

I have an extensive background in AL (6502 and x86) along with C+/C++ as well
as mixed language on the Apple II platform (i.e. Basic/AL)...

Here is a sample input routine with a couple of AL listings:

The only way you can "contact" me is by e-mail or through the commentary on this page...

Have a constructive and productive day

SL

that's a lot of code

Thanks for the reply. Excellent looking code! When it gets closer to rough-draft time, I'll contact you.
Cheers,
Chris

THIS IS SO COOL! :D

shlewap2 and Chris,

I cannot tell you how happy it makes me to see the two of you discussing Roger and the productive activity of the STAP project. Chris, you are doing a bang-up job as our first Volunteer Archivist! Thank you both for your involvement and interest in this project. While this is full of pleasant memories for many of us, the 48 monthly issues of Softalk are an incredible historical documentary resource. You folks are helping us preserve and explore this remarkable resource.

The fact that we had our first comment post with an assembly language listing is simply icing on the 6502 cake! ;-)

Thanks for the Compliments

To Mr. Salmons and the Project Staff:

Thanks for the compliments.... There's a lot of "scattered info" I gathered to produce
the listings as well as "physical" (i.e. at my hands) items (i.e. Nibble Magazine,
Compute Magazine (scanned and unscanned), Compute Books [Apple ML for
Beginners; First and Second Book of ML]) plus trial and testing to make them work...

In just asking... When will the Softalk PDFs be available? Late May or early June??

Have a good and peaceful weekend to all...

SL

Hey SL,

Hey SL,

There will definitely be the first 2-4 issues released by early June. Developing the best workflow and standard for metadata and colophon, etc. is a "one off" task that slows down the beginning of this process. But once we've nailed it, we'll be able to replicate the process and get better/faster as we go along.

Again, since we are working with the Stanford Digital Repository for long-term storage of the Softalk archive and donation of the entire STAP project website and its (eventual) FactMiners Fact Cloud to the Libraries' History of Technology Collection, it is important that we do this right not fast. I'm sure you appreciate and support this goal of making sure Softalk lives on forever (so to speak). :-)

--Jim--

Thanks for the Update

To Mr. Salmons:

Thanks for the update... Take your time... Cannot rush a "treasure" that Tim Cook "wished"
he could support... Maybe you can "nudge" him to help you out financially on the project.

Good Day

SL
