Another CHM volunteer (from the PDP-1 Restoration Project) and I pushed for an IBM 360/30 Restoration Project, and the ability to build replacements for failed SLT modules was part of our plan. I donated a 2540 Reader Punch to CHM with the hope that it would be used on the 360/30, but unfortunately I missed out on getting the 2821 Control Unit that went with it. Unfortunately, for various reasons it is unlikely that the CHM 360/30 will be restored.
