This Web page and archive built by Herb Johnson. Last updated dated June 21 2009.
Emmanuel Roche, AKA "French Luser", has posted into Usenet newsgroups, software (his and other's), documents, and commentary on and about CP/M for several years; including transcripts of original documents. His intentions were to preserve and distribute these documents via Usenet newsgroups, primarily comp.os.cpm but previously comp.os.cpm.amethyst (removed in 2006 by a Usenet committee).
In late 2006, I established this Web page and archive of some files, to encourge others to grab copies of "his" work and to archive them. A few sites and persons did this: they are listed below. But there was only sporatic interest by others to actually grab other files and offer them to me in this way. Roche himself, often references his "work" beyond his posts as not yet "ready", or to be available post-mortem.
In 2007 and after, Roche's posts have more often been impolite and self-serving: he often posts about what he has done or is going to do. When he brushed off a private email from me to assist him on studying 8086 assembly and publically insulted my skills, I decided to reduce my support. He fails to see why his posts are poorly recieved. By early 2009, his posts were intermittantly hostile as he treats some people's work as less than his own; or when he discusses politics or personal issues. He often refuses to cooperate with CP/M Web sites who host archives. He has been rebuked on a number of occasions, or actively argued with (a kind of encouragement, see this Web page).
However, there is often some good content in his posts; he provides some useful material and original work; and he is occasionally cooperative and supportive. So members of comp.os.cpm tolerate his behavior, in general. I will update this page on occasion.

As of Dec 2006, the Roche files I accumulated were archived on the "unofficial CP/M Web site" of Gaby Chaudry: thanks for her support. She had an accumulative "mirror" of this page at this link. Some other Roche documents are on her other Web pages: namely, some "DR Logo" documents.
As of late Dec 2006, Piergiorgio Betti agreed to copy my archive. Check his archive at this link. He also archives, or links to archives of, other CP/M related material on his Web site.
In addition, the Norway-based (Dutch-language) site nostalgia8.nl of "Katzy" has some of the Dr. LOGO documents provided via Roche.
By 2009, there are more Dr. Logo programs there.
As a seperate issue, Roche was part of a comp.os.cpm discussion of early 8080 floating point code. As a result I have archived some Lawrence Livermore Labs code which was retyped from documents by Roche, and also some code from Chuck or Charles Falconer. Go to this Web page for details and that archive. Roche typed in some of the LLL sources but not the manual, which I have included.
In 2009, Roche became interested in PLMX, a PL/M like product of SYSTEMS CONSULTANTS INC or SYSCON, sometime in the later 1970's.
This Web archive has/had a set of PLMX files as "Plmx.zip". Roche apparently has disassembled a few
of the files into PL/M code. He also added two magazine ads from Syscon as PDF's. He sent the results to me. So I provided a notes document with this information and the ZIP file is available from me at this Web link.
