The UCLA The Xerox Sigma series also used EBCDIC (probably not a surprise -- I believe the precursor company, Scientific Data Systems, was founded by ex-IBM folk). One nice thing about EBCDIC was that, in hex, the characters could be mapped quite easily with Hollerith cards -- the lower nybble mapped to the card 0-9 rows, and the high nybble correlated to the top card rows. Of course, the Sigma was a weird machine all by itself, what with over 200 discrete hardware interrupt vectors, four-bank interleaved memory, etc. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
