And the blog post notes the outfit that did them was started by a couple of former Commodore employees,  The C64 came out in 1982 , which makes the choice of the Apple IIe as the host computer you would upload the data to a bit surprising.

It would never have struck me that something like this was available so long ago -- I wonder what the guys who were working on that technology think of the stuff we have available to us today (like Bluetooth and the micro-miniature MEMS sensors)?

Just venturing a guess here, but I suspect they're probably working on similar things now and LOVE the new tech!

That would be the early 1990's for the shoe phone.  Sports Illustrated had a promotion where if you subscribed to the magazine, you would get a free shoe phone.  This was an important accessory to anyone's stylish apartment.  While the shoe phone was laughed at at the time, it appears they are now commanding up to $35 on EBay.  In a few years they could be worth thousands of dollars.  I think they should relaunch the promo and also do a new commercial with a Seattle Seahawk phoning his mom news of their victory on a shoe phone.

I still remember when I saw my first cordless phone -- I think that must have been in the late 1970s -- we all thought that was really cool.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
