Exploring the 71 IDS - John Baker
I am perusing what I can find regarding Titan and M-Code.

I keep bumping into the name John Baker and how amazing his Column in CHUU called Exploring the 71 IDS is (or was).

I have browsed what I have, Jakes USB, This site and CDs and - well - google, to no avail.

Does anyone where else I can turn for this?

John Baker's articles in the CHHU Chronicle are available in at least these two places:

-- Jake Schwartz's collection
-- Official HHC 2019 USB Drive

Here's the index of his "Exploring the 71 IDS" columns:

Thanks a lot Joe, i doubt I would’ve found it without you screenshot. Had it right under my nose, but could not see it.

I have taken the PDF pages I wanted and put them through PowerPDF into a word document, once cleaned, then back into Searchable Pdf. That helps with the reading and navigation. Now the articles has turned into a small booklet called “Exploring the 71 IDS” - happy I am.

RE: Exploring the 71 IDS - John Baker
John was by far the most prolific HP-71B LEX file author, writing nearly as many himself as all the other non-HP LEX files combined. He also got heavily into the FORTH/Assembler ROM itself and released several patches including 1 huge re-write of major sections of the Assembler itself (in FORTH).

I corresponded with John starting in 1984 and continued for several years, but the eventual rise of the home PC lead us in different directions. I tried contacting him not long ago, but of course the contact info from the 80's was no longer valid.

Other articles by John can be found in (all contained in Jake's Collection):

PPC Computer Journal, V3N6, Nov/Dec '84
PPC Calculator Journal, V12N2, Feb '85
Datafile, V5N03, V6N4
Sept '86 CHHU Conference in Washington DC proceedings

Also, there are many of John's programs included in Joe Horn's LIF Disk Project, described here:

https://www.hpmuseum.org/forum/thread-2520.html

including lots of LEX source files.

Another great source, in case you aren't aware (but almost certainly are) is JFG's website sections for the 71B, found here:

What specifically are you looking for?

Take a look here Restored IDS articles

I took some time to make these excellent articles easier to read.

Have fun
