Hi, maybe some Europeans may still remember the SC/MP project in Elektor/Elektuur around 1978. The hex monitor program "elbug" was published as a hex dump in issue Jan 1978 (German, maybe with a delta in other countries). This code did not yet appear in Internet; it is of historical interest, IMHO, though. You can find a commented listing at the following link: http://www.scribd.com/doc/18114130/ELBUG-monitor-listing (no, I won't accept any discussion about "better uploading to bitsavers" any more, Al may have a reason to ignore/neglect/reject my submissions). Regards Holger
