This is just for a bit of fun, now you can 3D print your own APL\360 typeball ('golfball') for a Selectric, I/O Selectric, 1052 printer-keyboard or IBM 1130:
You can find it at https://www.thingiverse.com/thing:4126040
I had a go at doing the ASR 33 chad bucket in CAD so you ought to be able to just print one off now.

I have an MDB Systems workalike LSI-11 backplane which I am starting to get working. I thought it would be nice to build the DBCOK logic and console switches to have the same look and feel as the original PDP-11/03 console so I scripted up the specific DEC switch paddle and LED receptacle as part of the project (which is ongoing) so they can be 3D printed and use a tiny Arduino to do the powerup sequence.
If you have a PDP-11/03 or a PDP-11/05 with missing or broken switch paddles then
In case you need some stopgap inserts in a /360 or /370 console, until you find the originals (which I have found is very difficult).
They pass the 'Six foot Rule' test ie. they look good from 6 feet away.

If you have a paper tape reader and no punch, you can now make real working paper tapes using a normal home stencil-cutting machine.
I've written a small command line utility that can take a .PTAP (or any other binary or textfile) and generate output that these
machines will cut. that your reader will read.

It can easily make repair pieces for existing old broken tapes from any byte offset. In addition it can
