Bored OS-tan Doodles again

Part ??? in my series of "this is what I do when I'm bored and have a pencil and pad of paper on hand" artworks.

In no particular order (since that would RUIN the fun of having to find them all for yourself) we have:

-Multics-sama
-DTSS-tan (initiating squirrel freakout mode)
-NOS-tan
-NOS/VE-tan
-MSDOS-chan
-Commodore PET-tan
-NLS (oN-Line System)-tan and WAITS-tan
-Whirlwind I and Harvard Mark I-tan (summer attire)
-SCOPE-tan
-SAGE-tan and IBM 728-kun. "Do my hair, dammit!" (Mostly a reason to draw what's under her formal coat-thing or whatever, since most of it gets lost under TONS OF RUFFLES)
-PDP 1/Thor-chama
-Berkeley Timesharing System (BTSS)-tan. A character I created back in '08 and just sort of abandoned until now. I think she's due for a second look, though, BTSS DID sort of influence Tenex and Unix and ran on the same hardware NLS did (see above)
-BUIC-tan and KRONOS-kun. Someone's obviously piggybacking...
-Honeywell Kitchen Computer-tan (serving up Cupcake a la Flames)
-Windows 1.0-tan
-And a random killer spacebunny.
