Which Sony Demonstration Tape Came with which TPS‑L2? Model-Specific or Regional Variations?

Which version of the 'Sony Demonstration Tape' came with which version of the TPS‑L2?
Is this related to the TPS‑L2 versions or was it a regional thing? For example, did the TPS‑L2 in Japan come with one version of the 'Sony Demonstration Tape' and in the US with another?

Thanks in advance!

YEKS-1 (CD-812) vs YEKS-63

 

For this video I used YEKS-1 (CD-812). No comments that indicate its the wrong tape The Walkman and tape are both from the European market.

 

I've seen TPS-L2's with both versions of Demo tape on eBay and elsewhere on the internet.

What interests me is:
1. Did Gen 1 (Guys & Dolls) came with YEKS-1 and Gen 2 with YEKS-63?
2. Did Gen 1 (Guys & Dolls) came with YEKS-63 and Gen 2 with YEKS-1?
3. Was it a regional thing?

Edit:

As soon as I posted this I've found on Discogs that YEKS-63 was released in 1982. So it probably came with later models of Walkman.

 

@Mladen Gavrić : the info below is from Walkman.land, behind the scenes: CD-813, CD-814, CD-816, CD-817 and CD-818,
I did not add all parts of all models, that is not the intention. For 250+ models I started to add 'important' parts, like ICs, motor, heads, and also demo tapes.
Although Sony did not continue for a long time to provide demonstration tapes with their units.

TPS-L2, WM-1, WM-2, WM-3 seem to all have come with the CD-813.
It was available once for 6USD from Sony Parts; now out of stock, as its replacement.

I found several references to YEKS-12 (eBay, pictured below) and YEKS-63 (for instance old-boomboxes, they state release year '83) for the CD-813.


In an older thread here on S2Go, members mention CD-812 came with an early version of the TPS-L2.
When searching for CD-812, YEKS-1 is the one I found. I can not find a reference CD-813 in service manuals though.



Let me know when you crack this nut, I will update the info on WML.
We are planning to make some of the parts info available on the site this year.

Hi @Emiel

Yup, according to old-boomboxes CD-813/YEKS-12 was released in '83 and came with WM-20.

Also, according to old-boomboxes and compact-cassettes CD-811/YGSK-104 was released in '79 and came with early TPS-L2
CD-812/YEKS-1 was released in '80 and probably came with later versions of TPS-L2 (I've seen lots of eBay and YahooAuction listings of TPS-L2 with that tape).

Anyway, if I find something definitive, I'll let you know.

I also plan on scanning and listing all the documents/papers/brochures (Names/PartNo) that came with TPS-L2 and posting them here somewhere.

 

The service manuals on WML do not indicate Sony shipped the WM-10 (and relatives) with any demo cassette.
Keep us posted. Together we can uncover the mystery of demo tapes!
