1. "Building the Backplane Connector"
Adam Trionfo · Fri, 5 Mar 2010 07:10:
I knew that I had some information about how to build the 2068's backplane connector. This is quoted from the book:
"Powerful Projects with Your Timex / Sinclair" by Jim Stephens
The title may make it seem otherwise, but this entire book is dedicated ONLY to the T/S 2068. This book was published in 1985. I picked this book up on Amazon in 2008 or 2009 (I've mentioned it to this group before). Currently Amazon doesn't have the book, but you can view the pictures of it that I uploaded to them. Here's the link:

http://www.amazon.com/Powerful-Projects-Your-Timex-Sinclair-Stephens/dp/0673180387/ref=sr_1_1?ie=UTF8&qid=1267801377&sr=8-1
Here is the quote about the backplane:
"First we need to obtain a 0.1 inch twenty-six to fifty-pin double-sided connector and cut off each end in order for it to slide onto the middle of the backplane. This connector can be obtained from most electronic supply outlets and should be one with pin spacing of 0.1 inch (with a pin centered every tenth of an inch). Any other spacing will not work."
This gives you a taste of what you need. The book has pictures and more information. I'll scan these few pages in and upload them to the file area as a PDF document.

I've scanned in part of the book "Powerful Projects with Your Timex/Sinclair" By Jim Stephens. This section, pages 81-87, talks about the T/S 2068's backplane connector, including how to make an adapter to attach to it. The book has been added to the Files section of the 2068 group in a new area called "Book Excerpts." The name of the file is "Power_Projects_(Excerpt-Backplane_Connector).pdf." Here is a direct link to it.

I'm only using the TinyURL link because the actual link is REALLY, REALLY long and I'm positive that it won't if I paste it in this posting. Remember that in order to download files you MUST be logged in to the message board.
I hope that this helps.

I should have pointed out earlier that the connectors that you'll find nowadays are measured in millimeters. If you're LUCKY, the connector will also say 0.1". For this reason, it's VERY good to know that the type of connector that you're looking for is 2.54mm spacing.
Here are some options from Mouser Electronics:

Here are some options from Jameco Electronics:

Not all of the above options will work, but the way that their filter works, I couldn't get EXACTLY what I was looking for in a search. Still, this is pretty close to what you need. It's too bad that there isn't an edge connector that will work off-the-shelf. No matter what, it looks like even the "best fit" will have to be modified.
Hope that this helps.

Thank you Adam for this information.
About the book, I scanned it and uploaded it to the world of spectrum last year. It's available for download here:
http://www.worldofspectrum.org/infoseekid.cgi?id=2001107
All the material that I scanned that couldn't be hosted on the Yahoo group was uploaded to the WOS ftp, where a Timex archive is being prepared.

Glad to see that! It's full of useful information. I've wondered how come their are so many books for the T/S 2068 even though it didn't sell well at all. Is it because it was T/S related and it was EXPECTED to do VERY well? Or was it just a simple matter of changing Spectrum books for the T/S 2068?

While many books did just change the differences, there were a lot of electronics oriented and ham oriented people who were really into the myriad of personal computers back then.
Also I don't think Timex sold as few computers as they would have wanted the world to believe. There were far too many people in our Timex computer club for the computer to be that rare.
And I still run into loads of people that had one of the machines.
