No way! I actually find a use for those two now and then. And back when the 41 was new, octal-based machines like the PDP 11 were still fairly common.

Agreed, Octal was low level predominant and remained so for at last a few more years until hex (and 16-bit) architectures were commonplace.

[In 1979 I have no doubt the PDP-11 was the predominant mini however already in decline with the VAXen.]
