Bil, amazing: I was reading about you on the book "On the Edge" and when I 
stopped for a while and I got a quick glimpse on my notebook, I've seen your 
name on the latest email received :)
The work you guys did about the C128 was terrific, indeed. But how did you 
solved the video chip problems? You told you have had many troubles with it, 
due to the poor design (at least this is what I understood), including the 
problems you had showing the C128 prototypes at CES; but there's no 
explanation on the book about how you fixed them later or I missed that 
part...

The connector itself was a product of mechanical design in the Tokyo Office:
Ira Velensky did the design  where he specified the connectors needed to
meet the footprint requirement as defined by JT.  My memory is he told the
vendor the size he needed and they created the connector for him/us, or at
least ramped up production on what had only been drawings.  The TED had no
reason to have a C64 cart interface and 2mm offered a much denser connector,
the joystick DIN's fit correctly in the slanted part of the case.

For those that may not have seen it, I rant about the 116, which drove the
TED family, at http://c128.com/c116

The ULP I have will do any spacing.  It's how I created my .1" and .156"
ones.  It'll take a bit to find it, though....

Now, you're just trolling :-)

Let's see if Bil pipes in.  He got the +4 project at some point, maybe he
knows why...
