    Hi Dave, The varying orientation of the LEDs will make any build tricky. I suggest you make them all the same. Cheers Tom

APL\360 typeball for the IBM 1052 and I/O Selectric

by 1944GPW on January 24th, 2020 at 11:01 PM
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:

DEC PDP-11/03 switch paddle, LED receptacle and console board

by 1944GPW on March 16th, 2018 at 11:21 PM
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

IBM System/360 and System/370 console button replica inserts

by 1944GPW on December 9th, 2017 at 11:19 PM
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.

PTAP2DXF - make paper tapes without a punch

by 1944GPW on December 1st, 2017 at 06:04 AM
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
