  1. Yet another nice Asianometry video, this time history of DSL.

    Of course his (loosely paraphrased) comment on "DSL not widely used anymore but it'll remain in the backwaters for a long time" is peak hilarious to any German.

    Worth your time. Got some fun comments too.

  2. Does anyone happen to have any documentation for a British Telecom "Tester 420A" ISDN BRI tester.

    Also known as the T4200 - seemingly made by Fulcrum Communications in the early 1990s

    It's throwing some error codes at me, and I'd really like to know what they mean!
