uhh... are you saying that because it is 8 bits? Or you are just joking around with a random numeral system?

I'm really old school digital, I use fingers and thumbs.Greg surly binary is 0 & 1s, and this is octal

Greg it was light hearted, but 2 digit is binary, 8 digit is Octal, 10 digit is decimal, and 16 digit is hexadecimal

That's really useful to know but I wonder if, when I stick two fingers up at some one, they realise I am signing to them in 2 digit binary, and will that actually stop them from thumping me.Greg it was light hearted, but 2 digit is binary, 8 digit is Octal, 10 digit is decimal, and 16 digit is hexadecimal

I see, actually the number of digits is irrevelant.... the number of "numerals" is what makes it.... to be precise but there is no octal in this hobby, not even hex is used.Greg it was light hearted, but 2 digit is binary, 8 digit is Octal, 10 digit is decimal, and 16 digit is hexadecimal
we do binary or convert to decimal... so I did not see where any octal was used, so I was confused... I was using octal in 1969.... when processors were small, very small, and memory was REALLY expensive and blew up at the slightest static charge.

Ah, memories (no pun intended) Messed around with (amongst others) a Ferranti Argus system 600 when at college. Wrote a working program in octal (Assist?) to control a small layout, single track with a passing loop, each loop road two trains long. Shame the lab assistants didn't make the interface on time. Managed it many years later on a BBC B. That Ferranti was state of the art at the time, the donated ex Rolls Royce valve powered analogue computer was something else!

yep, my current wrist watch has more memory than the computers had at college when I started...
