The card with the Seagate labels appears to be an 8 bit ISA controller card for up to 2 MFM hard disk drives (these would almost certainly be 5.25" drives). 

 

The card with the RAM chips down the left hand side looks like an 8 bit ISA Hercules compatible monochrome graphics card - if you google it you should find a picture of a pretty much identical card on Wikipedia - the 9 pin connector is for the monochrome monitor & the larger is almost certainly a parallel port.

 

The card that has the jumpers to enable or disable the printer is presumably a parallel port card - possibly with a serial port or maybe it's another Hercules compatible graphics card but as I cannot see the connector on the photographs it is not possible to tell - it should allow you to determine which it is though.

 

All these items will only have any value if you can find someone who actually wants some of them - most of this stuff went in the bin many years ago (I think the last time I saw an MFM controller or Hercules card would be well over 20 years ago).

eBay is the only place to go to value them.  Put them up for bid at $0.01 plus a shipping charge.  see where it goes.  PS have better well lit non-fuzzy photos showing all sides of a part.  See if others are already auctioning similar cards.

 

Only industrial labs with archaic PCs running archaic machines (robotic or data collecting) that cost too much to replace or are irreplaceable for some reason still have a need for 8-bit ISA components.  And even then you are offering untested (unwarranted by you?) old components so that hurts resale value.  Still beggars can't be choosers.  And these things have long ceased production and are now only repaired by an ever dwindling supply of people qualified to diagnose and repair them.  [There is still a obscure MB maker selling ISA slotted new expensive micro-ATX MBs for these PCs, which usually means replacing the case since its design predated the ATX form factor.  Often even the AT form factor.]
