Have dumped the EPROM and made several passes with the dissembler to separate the data and code.
Total code and data is 0x1823 bytes. 
Some text decoded thus far :
 
;
L0216: DB '.5 MHZ RECEPTION SELECTED                .'
;
L0240: DB '.10 MHZ RECEPTION SELECTED               ..15 MHZ RECEPTION SELE'
 DB 'CTED               ..ALL COUNTS HAVE BEEN CLEARED            ..P'
 DB 'RESS CLEAR AGAIN OR OTHER KEY TO ABORT ..WWV TIME MEASUREMENT IN'
 DB ' PROGRESS        ..WWV'
 DB ' TIME CORRECTION RECEIVED            ..NO '
 DB 'WWV TIME CORRECTION WAS RECEIVED     .'
;
 
<break>

;
L104B: DB 'TRIES=.'
;
L1052: DB '5M=.'
;
L1056: DB '10M=.'
;
L105B: DB '15M=.'
;

My next step will be to hook up a terminal to see these status messages and maybe the TIME is also produced in ascii readable form.
