Sounds like you've discovered the classiccmp version of the "guess the
number of pennies in the jar and win $100" game. A grand prize of 300
5.25" floppies goes to the person who can correctly name all the connectors
on the back of the most obscure machine that Fred can come up with. <grin>

! > Slot 1 : Female DA15, Female DB25
15 - joystick port, 25 is printer port, and I bet these go to the same
card
as slot 5, the DB 9 and DB25 serial ports...
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.

! No idea, but from you, probably something homemade :-)
Hard drive controller?
EPROM programmer, expansion chassis?
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.
! > Slot 3 : Pushbutton switch, Mini-DIN 6
! The switch might be a reset, but no idea on the mini-din 6,
! M$ bus mouse
! perhaps?
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, ...)?
! > Slot 4 : RCA phono socket, female DE9
! That's your video card I think.
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?
! > Slot 5 : Female DE9, female DB25
! serial ports
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?
! > Slot 6 : Female DC37
! again, I 'm not sure what a DC connector is.... is it a floppy
! controller? I can't recall the pin count.
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.
! > Slot 7 : Male DB25
! parallel port?
MALE!!!
The most common use of a MALE DB25 for a PC is serial.
! > Slot 8 : Female DC37
! ! a second floppy
controller?
Also on the back : another male DB25, female 5 pin
DIN, ! male and
female IEC mains connectors. ! ! The DB25 could be another
parallel port,
MALE!!!
serial
the din 5 your ! keyboard, and I ! don't know what
IEC
is, but since you say mains I assume that's your ! power cord and
monitor power points.
