Started off looking at [BYTE, SERVER, HOST, RAM] as a set but wrote it off quickly because the terms seemed tangentially related at best, and [SERVER, HOST, COMEDIAN, DISHWASHER] looked like it could be “jobs” or some such. Also thought that DRILL and BRIDLE could almost be part of a “tools” set; or, with the addition of RADIO, maybe “things in a shed/shop” or similar. Then “bit” just sort of clicked in my head, and as soon as I had the thought, I knew it was weird enough to be the purple set. All the others fell into place immediately after.
