Yes, the 6157 was used with the RT/PC, but was also used on the
System/36, PCs (with the 8-bit ISA adapter used on the RT/PC), PS/2s
(with the MCA adapter), and others.

It uses the DC-600 series. The DC-600A can be used in both the
6157-001 and the 6157-002. The 6157-001 typically uses DC-300 series

I suspect that the female connector was used so that folks would not
accidentally attach the tape drive to the external port on a floppy
adapter (PC/XT style or the "Bond" PS/2 5.25-inch Diskette Adapter/A).
The biggest problem for most people who wanted to use the 6157 on PCs
was the general lack of device support. Sytos supported the 6157, but
most PC tape packages did not.
