Please help me ID these EPROMs

I was going through some boxes today and found the EPROMS described below.
Does anyone know where they are used?
I mostly deal with Apple II stuff, so I suspect they are for Apple II cards
 
27C128 EPROM

The label is hard to read.
I looked at the contents of the EPROM on my programmer, it looks like it
may be from a Data Link 2400 modem.

I suspect it is the EPROM from the CMS SCSI Card for the Apple IIe/IIgs

If anyone can id these, please let me know.  E-Mail reply is best.
Thanks

PS I'd like to find out what they are before I erase them.
If they are of any value, I'll save them to disk files before I erase they.
