SIM990/DX10 help?

Yeah, I kind of "figured it out"... poring through README.txt and just
noodling around a little bit. So, you extract the disk images and run
sim990 (still, from a SSH session via PuTTY):

sim990 -m 10 -s 512K -c dx10.cfg

Once it starts up, from within that window, I found I could hit Esc (not
F10) then "!" and then I got an SCI prompt and a message about the system
being uninitialized!

I ran a "IS" command as described in Vol. 2 of the DX-10 documentation...
this system is pretty easy to use... just filled in the date and ran with
defaults otherwise. It churned for no more than 30 seconds and eventually
it lands at a QUIT message. I let it sit for a while and once I convince
myself it's idle, I try poking at it again...

Hit Esc and "!" and I get prompted to sign on to SCI now! I logged in with
the username and password given in README.txt (SYS001/SYSTEM). I get the
SCI prompt at the console, I can run commands just fine. Cool!

So, now that I can use the system from the console, I'm trying to test it
with Telnet again, to see if it'll behave differently after the system has
been initialized.

I find that now when I open Telnet sessions to port 2000, I get a prompt to
signon to SCI, which I didn't get before, and if I create a new user
account for myself using "AUI" at the console, I can get logged in. After
login, I'm at the same menu I saw before, but I still don't get a SCI
prompt in the Telnet sessions like I do from the console.

I strongly am suspecting it might be an "emulation" issue with the Telnet
sessions, where the console is set up as a "TTY" while it is expecting the
Telnet sessions to look more like a TI VDT. I'm still poking at it but at
this point I'm confident I'll get to the bottom of it... or... I can just
use it from the console, failing all else.

The scheme used for user accounts in DX10 is bizarre and amusing. It took
me a minute to figure out that the user ID /is/ the three digits in the
account name and they need to be unique across accounts! LOL

Woo hoo!
