The 2 empty sockets near the edge connector are for the optional FPU co-processor & optional IBM FDC (
Floppy
Disk
Controller) chips. The original price on these GG Bridgeboards were around US$800 for the 386slc & US$1100 for the 486slc2. These chips, if included at the time, would've hiked the price up even higher, so the designers did not include them, although they gave you the option of having the capabilities there if you would buy them & install them yourself.
All the Vortex Golden Gate Bridge Board let you use your built-in Amiga drives for IBM emulation, but you're better off using a real external IBM floppy drive, as this was faster and could even support the PS/2-style 2.? meg floppies, reading & writing, which, even if you had an Amiga high density floppy drive, could not do because of its controller.
The Monitor Master allows you to use just one monitor for both the Amiga that the board is in as well as displaying its output when it is in use. There's a combination of using one of the Amiga keys in combination with another keyboard key to allow you to software toggle between the 2 displays.
The Monitor Master connected to the outside of the GG's Bridgeboard, (a.k.a. an edge connector). The other edge connection on the GG bridgeboard is for an external IBM-style floppy drive only if you've got the optional FDC chip installed.
The connector at the top right of the card is for an internal IDE (usually a hard drive disk) drive of some sort.
I don't know if you could run Windows95 on it. Don't even try installing it if you don't have the optional FPU chip installed. Windows 3.11 works, but a better & faster GUI would be the
Breadbox Ensemble. It's got all the web clients, too. It used to be known as GEOS in its earlier incarnations.
Breadbox Ensemble will crash PC-Task (I've got ver. 4.4) because it bangs the metal.
