Atari 835 Field Service Manual -- Canadian TAP cord?

[ldelsarte]

Dear fellow Atari 8-bit fans,

 

I was reading this document:

Atari 835 Direct Connect Modem Field Service Manual - FD100268 Rev.1 March 1983

(https://www.manualslib.com/manual/1245202/Atari-835.html?page=35#manual)

When I noticed something I never paid attention to before:

 

Page 5-1, Parts list

CO60557 FCC Phone cord

CO60558 TAP (Canadian) Phone cord

 

Questions to you guys:

- Where the two cords included in the box?

- Was there one box sold in the USA with the CO60557 FCC Phone cord, and a different variation sold in Canada with the CO60558 TAP (Canadian) Phone cord?

- What is a TAP phone cord anyway?

- Why do these two part numbers not appear in the engineering parts list of Jan 13, 1984?

 

Bonus question: Does anyone have seen the original "Atari 835 Test Diskette" mentioned on page 3-1? Does it have a reference?

Thank you for your expertise and advice...

Kind regards,

Laurent

So, is there really no Canadian Atari fans here who could  tell me what a "TAP Canadian phone cord" is and why it's so different from the US FCC phone cord?

Could be the 4-prong connector that old phones phones used, mostly the Bakelite ones.

 

These weren't specific to just Canada though: https://en.wikipedia.org/wiki/Telephone_jack_and_plug

Thanks a lot. I had never seen it (I'm French).

I assume that Atari had the 835 distributed both in US & Canada :

- in the US with the CO60557 FCC Phone cord and English manual

- in the Canada with the CO60558 TAP (Canadian) Phone cord and English & French manuals

That's only an assumption.

 

But thanks for your reply, @Nezgar, it really helps
