Hello, DEC enthusiasts -
I've got some 5-1/4" disks here that purport to be from a DECmate
(probably II) and may have data offloaded from a bigger system. But the
disks don't have any recognizable trace of a filesystem on them; just
vast swathes of data that looks like this:
https://drive.google.com/file/d/12EO4Lg1Uh7NvCUJksHQ2AUiK550OX7UJ/view?usp=…
It seems to be a pattern of a near-zero byte followed by some other
byte. It's like they're storing 12-bit words in 16 bits or something.
Does anyone recognize this sort of thing, just eyeballing it?
