The most common uses in a PC for a female DA15 is joystick.
The most common uses in a PC for a FEMALE DB25 is printer.
But the FEMALE DB25 could be SCSI, and the female DB15 could be sound.
But keep in mind that Tony's machine might not be very ordinary.

Although male DB25s are most often serial, and FEMALE DB25s are most often
parallel, they also get used for a LOT of random other general purposes.

Based on Tony's feelings about mini-din, I'd have to assume that it is a
commersial product that he has yet to get around to customizing.
Non-maskable interrupt/hardware debug assist (Atron, ...)?

The most common card for a PC with RCA socket and female DE9 is CGA.
No homemade notch for access to the 4 and 6 pin bergs?

FEMALE!!!!
The most common card for a PC with FEMALE DE9 and FEMALE DB25 is the IBM
"Monochrome Display and Printer"
No notch for access to the 6 pin berg?

The most common card for a PC with female DC37 is the IBM Floppy disk
controller.
But it could be SCSI, expansion chassis, or miscellaneous homebrew.

MALE!!!
The most common use of a MALE DB25 for a PC is serial.
