The situation is actually a little different from this.

   wd8003e	Configured with jumpers, has 8K ram for buffering
   wd8003ebt	Also configured with jumpers, has 8K or 32K buffer
		option, has ROM socket to allow support of diskless
		"workstations" (boot ofver network)
   wd8003eb	Software configured, has 8K buffer

My understanding is that the e and ebt versions have been discontinued,
being replaced by the eb version.

I am not familiar with the 16 bit cards so cannot comment on them.
