I have OS 2.43 on there - when I got it from my friend, it had 2.21 on it ;) - I know it won't run under 2.30 because it uses specific BCALLs from 2.30+.

Maybe I should mention this, but it is probably not important: it is a teacher edition (aka has the extra port above the LCD).
That's not important. I had this error once, and can't remember for the life of me how I fixed it. (cursor in the top left corner).  Put calcsys on there. Load a flash drive with 2 files. (A.txt with no data in it and B.txt with the "THE GAME" as it's contents).  Make sure the flash drive is formated as fat16. I would suggest using the smallest one you have, like 512 MB or something.  Plug the flash drive in with the correct cable (mini-A to standard male A).  Then, run MSD8x.  If this doesn't still give you access, go into calcsys.  Go to the hex editor. Type Alpha and then G. Type in "4000".  Then, press Alpha and then R. Type 87.  See if anything about A.txt or B.txt is on there.

...Put calcsys on there...
Already got it  ;D
...Make sure the flash drive is formated as fat16. I would suggest using the smallest one you have, like 512 MB or something...
Got a 1 gigabyte drive formated as FAT16 (full of crap, but still).  Like I said, I can use my other calc ;).
...go into calcsys.  Go to the hex editor. Type Alpha and then G. Type in "4000".  Then, press Alpha and then R. Type 87.  See if anything about A.txt or B.txt is on there...
I assume this changes which page I am viewing in the memory?

EDIT: Okay, I'll go and try this quickly.  I'll report what I find in a bit.

Update:  What the...? First it started complaining my batteries were low  (error 1208, I think), so I changed them, and now it works fine again.  I don't understand - I've tried this before and it doesn't work.

EDIT:

Yeah, the usb driver can be fickle.

EDIT: Fickle meaning that apparently you can sometimes even reset your calc and it still won't work.  I got the exact error you did yesterday, with the cursor in the top left corner.  Plug in your flash drive into the cable, and then the cable into the calc, then run MSD8x.

Reproduced error - I tried something a little different than two blank docs.

Ran it correctly (the error only occurs sporadically now), opened a specific folder
Verified in Calcsys that it wrote to page 87h
reproduced error somehow (don't ask me how)
viewed page 87h again

Results:
No writing at all to page 87h - the content was the same both times I checked it.
Other than the blinking orange light on my flash drive, nothing happens at all (except said error).
Cheers!

It may have done it on a different page then. I'm not entirely sure. Try pages 80-87 as those are the ram pages. When I did it, it showed up on 87.

Okay - experimenting with extra ram pages - fun ;D

Calcsys shows that page 80 is essentially a copy (I think?) of page 87  (w/o running MSD8x, that is)
Page 81 and 86 are used by omnicalc to backup ram - I don't think it has written to either page, as ram restores have been normal
Page 82 and 83 are mostly junk (organized junk, however - no idea what it is used for)
Page 85 is confusing - I find recently run programs (names) and other assorted junk.

What kind of issue is this? Hardware? Software?  At this point I don't know what to think - it sporadically works and fails.
Cheers!

Most likely both hardware and software. The usb driver is strange, but we don't fully understand it either. And MSD8x could seek improvement as well.

Okay: I ran a test (this time actually triggering the bug) and it appears that no pages get written to.  Any ideas now? :banghead:

Not a clue.
