Byte addresses increased byte by byte as did words increase word by word Everything else I ever saw except of course the VAX did it wrongly (That excludes byte only addressing schemes like the Motorola 6809 IIRC) OK 11's and VAXes made core dumps of text look ugly. Elegant as the VAX was, it was but a bloated 11 with a usable address space. The 6809 looked like an 11 that ran out of money. I guess everybody's idea of elegance is skewed by the first machine you really really loved. -- To de-mung my e-mail address:- fsnospam$elliott$$ PGP Fingerprint: 1A96 3CF7 637F 896B C810 E199 7E5C A9E4 8E59 E248
