    Thrift shop finds and a damaged MB

    Unless I'm missing something, what you've photographed is a WDFN-10, not a SOP-8. Happy to help!

    DW8E debugging

    Figured I'd start a new thread on the DW8E debugging on my Negibus 8/I. The symptom appears to be an accumulator that cannot be cleared during IOT 2, which is quite obvious when performing a KRS or KRB instruction with an M8655 in the DW8E. It's obvious that AC LOAD is occurring before AC...

    PDP-8 (and PDP-12, and....) Dhrystone and Whetstone

    Isn't 1.8 μs the intended performance, with the 1.65 μs cycle time from flipping over the G718? Or am I missing something regarding a true 1.6 μs cycle time from the factory?

    PDP-8/s restoration in OZ

    I wonder if it's worth using the Chip Quik low-melt solder to replace the bulbs for these early boards...

    PDP-8/s restoration in OZ

    That does not look OEM to me. Seems like they were interested in bringing up the output voltage by reducing the saturation.

    Interesting embedded system from the 1980s- a high-end reproducing piano...

    Testing my RK8E and failure ocure

    Do I understand correctly that it works with normal over-the-top connectors but fails when you use the long, cabled over-the-top connectors?

    Cleaning of dirty wire-wrap backplane

    I agree with David. Also, the older single-sided backplanes are likely more durable than the newer, double-sided backplanes. At the end of the day, unless there's some concern about the dust being significantly conductive on the wire side, I would gently brush it off and worry about ensuring...

    Making new CDC Phoenix air filters

    Yes, the filter itself is rectangular, but one would either have to carefully separate the adapter pieces to reuse them or fabricate new ones.

    PDP-8/S

    I would probably befriend a computer collector near the computer to aid in packing rather than trust someone at a packing service who has no personal investment in whether or not your item makes it safely to your door. Give them a little beer money to help pack it, take some photos, etc. It...
