Possibly, I mentioned this in the other thread. JDR Microdevices started 
selling stuff in 1979 and this board looks like it was made in 1980. I 
think this board might eventually turn up in an old magazine article or ad 
(Radio Electronics, Popular Electronics, Kilobaud Microcomputing, etc) 
since it looks like it may have been a kit.
