     I have an MFJ-1270B Turbo TNC.  I have access to an EPROM burner.  However, I need to round up somw 27C256 EPROMs to burn the UIDIGI code into.  

     I notice that 27C256s are being sold in small lots on Ebay.  

     Is there anything I should be sure of before purchasing them?  I don't know a lot about EPROMs, but I do remember what I learned about TTL in school.  There are variants of TTL out there and you need to get the right one in some cases.  I'm just covering base here.  

     Regards, 



                                       Fred
