I have yet to watch this, but I am pretty sure that the first two bytes of the loader, are 063, 307. I loaded Altair Basic dozens of times as a teenager in the late 1970's.

Am I right?

"First two bytes are 41 and 256," he says.

How would a byte be 307? Or 256, for that matter. I must be missing something basic. Hah.

[edit] Oh, octal. Five groups of three plus the one on the end. That makes sense and also explains how he's so easily plugging in the numbers.

Also DEC PDP's used OCD octal coded decimal - I had once or twice to manually load the boot strap when our pdp 11/40 boot strap loader subsystem had a fault.
