IBM224 Battery Solution

Short clip on a 3D printed battery replacement for the vintage IBM 224 Dictation machine. Two A544 Energizer 6-volt batteries work nicely as a replacement for the original 11-12 volt cell that is no longer available. The replacement solution will not last too long in this recorder, but works perfectly to be able to show off your 1972 Dictation machine. UPDATE:  I am thinking that I could find a 11.2 V LIPO that would fit nicely inside this unit and work for several hours.  Stay tuned.
