Compass clock?

Hi, When I was using the GRiD Compass yesterday, I noticed that the system clock was frozen at 17-Nov-1985, 9:01 p.m. I tried setting it for 14-May-1999, 9:46 a.m. I thought it would b frozen again at that time, but when I powered the beast up again to make this call I was surprised to see that the clock had advanced to 9:56 a.m.! :) And instead of the 15th, it says it is the 25th! Is this an early Y2K problem? :) Is there an evil battery inside, about to leak all over my precious bubble memory modules? Oh, and BTW, how much bubble memory am I supposed to have? Currently it has "334 in use, 52 free". That's 386 units. It says "Usage (in 1000s of characters)" beneath the system memory report (I can look at these things from inside GRiDVT100, luckily) but I'm not sure if it applies to bubble memory as well as normal system memory. After all, the bubble memory is where the filesystem lives, which is a bit different. My system mem is currently "System: 153 Application: 51 Data: 18 Free: 40". That's 262,000, which is about 256 when divided by 1024. Is GRiD-OS eating most of my memory? What a hog! ;) I found the little blurb in Popular Science, August 1982, p.42, and it says that the machine comes with 256K each of bubble and normal memory. And for $8000. Was there an expensive option to get more bubble memory? Or is that what differentiates the 1100 from the 1101? Oh yeah, where is the OS stored? And applications like GRiDWrite and GRiDVT100? The VT100 emulator seems to load slowly enough, which implies that it's in bubble. So, like, if I reformat my bubble memory, I'm toast, right? I would very much like to have some sort of backup of everything in bubble memory. I don't seem to have XMODEM or any other transfer protocols on this thing.
