     They are memory chips. Here is a snip from the newsgroup FAQs:

017- Where can I get the chips to expand my AE GS-RAM III memory 
     Expansion card to 4MB? 

     The Applied Engineering GS-RAM III uses 20-pin "Zip" package 1M x 4
DRAMs (NEC D424400V-80 or OKI H5144024-70). 

     As of September 1999, you could find the NEC chip at Spi Semiconductor
(orders: 818-349-4495; http://www.spisemi.com/index.html).  For other
suppliers, a fairly good try is a current issue of Computer Shopper magazine. 

     Whenever you order these memory IC's, be sure to confirm that the chips
are, in fact, in the Zip package.

     When you order the memory IC's it probably would not hurt to get eight.
It sounds like the board may have been plugged in backwards-- not sure how
this may have affected the mem chips.

     You can get TTL and other IC's from a number of places-- like Mouser,
Digi-Key, Halted, Newark, ... .  See the Vendors list at
