    Flip Chip pull handle model

    There's a painting tool, so you don't need to edit the G-code directly. Basically, the tool allows you to color a face, which is why the lettering is either recessed or raised. Otherwise the import wants to combine the co-planar surface, and there's nothing left to color.

    Not sure who this was addressed to, but my print profile is colored. I do not know of a way to get colors from OpenSCAD directly into the Bambu tools or OrcaSlicer. AFAIK, you have to import the thing and then color it. Thereafter, you can save the print profile to just reopen and print as...

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

    I tried to run this, but don't have a dk8p or dk8s running. I tried to port to the dk8a, but it looks like the code stomps locations 1-5, where I wanted to put interrupt handling for the clock.

    Technically, that drill guide is Doug's design. I just posted a print profile.

    I went and looked at the code. I think the main innovation was some gamesmanship with the DMA mechanism, which means no actual buffer is required. Instead, a single word is repeatedly hammered with successive words from the DECtape, and interpreted to set location counters, field settings and...

    Flip Chip pull handle model

    Fair point. Looking at the "publish" script for the 3D stuff, I see that I've got "TODO" comments where the source code should get published. So that needs work. Some days I wish I had staff, so that things like this didn't fall through the cracks so often.

    Here's a direct link to mine (mentioned above), which is also quite similar: https://svn.so-much-stuff.com/svn/trunk/3D/CardHandle/CardHandleL.jpg https://svn.so-much-stuff.com/svn/trunk/3D/CardHandle/ The .scad file is there, as is the 3mf profile I use to print on the P1S. There's a reusab;e...

    ISTR that P?S8 spent a fair bit of energy working to preserve a prior behavior, in which the loader had an amazing ability to load over itself. So even diagnostics and such that used the memory where the loader lived could be loaded. Does DIAL-MS have this ability? If so, it may complicate the...

    PDP-8/S

    I've had fair success at this, and even managed to print them with the module identifers. (I'm not sure where to get filament that will match the original red well.)

    I'm back at my desktop, and (assuming I can get it working properly again), should be able to help facilitate in the dial tool work.

    PDP-8/S

    The testers derived from Warren Stearn's work do positive logic. I started to do an adaptation once for negative logic, but never actually got it working. I know that Anders' tester is designed to handle negative logic. My impression is that it is working well (though I don't have one).

    H960 Question

    Yes, I meant that I have mounted things on the sides of the rack as well as in the front and back.

    H960 Question

    I've mounted power supplies and whatnot there. It's the same as the distance between the holes at the front.
