    300 baud, that was the same speed as the modem I used to do online shopping with in ’84.

    #21 Not as old, but I remember doing online shoping thru compuserve, as well as buying plane tickets thru a direct connection that compuserve had with SABRE. It was so amazing to be able to have all that “power” at the time. 2400 was the connection speed back then.

    When that SABRE link died, all those accounts were transfered to Travelocity.

    Now compuserve is finally dying (at least the “Calssic” access) this month.

    Man, we getting old or what!

  3. pedro says:

    Which reminds me. John, are you gonna give a nod to Compuserve now that is being (unceremoniously)shut down?

    300 baud? Why we WISHED we had 300 baud. We had 150 and we LIKED it. Not so sensitive to line noise by gadfry. And the paper tape punch couldn’t keep up with that anyway.

    #24. 150 baud?…Why we WISHED we had 150 baud, Hell, we were lucky to average 3 smoke signals, per minute!!!! And we LIKED it!!!

    WHY YOU YOUNG PUNKS AND YOUR FANCY SCHMANTZY MIGABYTES AND SUCH!!!!

    Nice post Cranky.
