Picked up the data general one on Trade Me, but no SW

Yetiseti bought one a while ago, have you got any software?
After lots of guesswork on power supplies etc, I finally have it going.
It has 336kb of ram, and the worlds largest 5.25" drive.
Unfortunately no cable for the drive which looks like 37 pin d-sub to 60+ pin IDC? (doubt I'll ever find one of those)
Reasonable condition, and the screen is as awful as the internet says.
