Hi Doug

I'm afraid that all I know about the IBM-Philco connection is what I have written in my site's History section (see links above).

I'm surprised it uses an RCA phono, given the enmity between RCA and Philco during the 1930s. But then again, Philco did use Victor (RCA) pickups in their radio-phonographs through the 1937 season...rebranded as "Philco", of course.

Edit: You folks should know that it was Doug, many years ago, who told me that Victor had originally developed the magnetic phono pickup used by Philco and other manufacturers for several years. Philco used the same pickup and tone arm, with few exceptions, through the 1937 season (37-650PX), complete with old-style Philco-with-lightning-bolt trademark!
