[aprssig] EPROM for UIDIGI

Folks, 

     I need to get my hands on a 27C256 so I can burn the UIDIGI firmware into it.  I went to the Jameco Web site to order some but there are a whole bunch of variants of the 27C256.  They can all be viewed at http://www.jameco.com/webapp/wcs/stores/servlet/CatalogSearchResultView?langId=-1&storeId=10001&catalogId=10001&searchType=k&searchValue=27c256&categoryId=105040.  

     I'd hate to order them and get one that doesn't meet the required specifications.  

     The differences seem to be in the speed and the voltages used.  

     I've got a feeling that one with 12.5 volts and a slow speed will work.  But I'd like to be sure before I pay Jameco more money to ship a couple of chips that the chips cost themselves.  

     Can anyone make a suggestion?  
 
     73, 



                                           Fred, WB4AEJ
