Thrift Store Old Computer Parts Pickup ID Help :)

I was at a thrift store and I saw these neat looking older, vintage PC parts. I paid less than $4 USD for these parts. One is a motherboard with an unknown Pentium chip in it. There also is 256K of Ram. The other two I am not sure what they are. Please help me ID! Happy

That Okidata set of proms is for

An old dot-matrix printer. Way back when to get a screen print you needed this so IBM PC screen dumps would work. Today? Best to never go near this since it's now E-waste and can cost you to dispose of it.

All the other items can be researched on google. Just put in identifiers off the board or chips.

Yeah I know just how you feel.

I can't resist a bargain? either. Have fun!

Socket 7 motherboards

Those would take both Intel and AMD chips in the same socket. It was after Socket 7 that each maker began using different sockets on motherboards to place their Central Processing Units in. Any 321 pin processor of that time will work in that socket.

It's a graphics card for extra video processing. Used in 90's CAD (computer aided design). For instance you might see video fine then in 640x480 at low dpi, or standard def, but photos and large image files you were processing took a lot of time using the standard video chip on the motherboard, so these cards without a video plug on them were used for very large image processing capability.
same era, the 90's
It's a Socket 7 motherboard with the cheaper S3 southbridge controller chip on it (see SIS) and looks like 72 pin SDRAM slots for memory. Looks like it can use a PCI or a VESA video card.
