I have a old Pertec computer that still workes (after one hour of
waiting
time to get warm). It 's a PCC2000. I live in the Netherlands, but i do
not know were to go to with this stuff. Could you help me. I got your
addres from jimw(a)agora.rdrop.com.
Thanks.

The usernames/passwords/privs are stored in a file called ACCESS.TSX.
The information is stored in a lightly encrypted form (no MD5 here) and
is most conveniently accessed by running TSAUTH. Many system managers
take the TSX+ manual's recommendation and remove TSAUTH.SAV from the system
disk, keeping it on a floppy for when it is necessary.

Who said we were getting up? Perhaps Hamfests start _just before bedtime_ :-)

Keep in mind that even a TSX machine has to boot through RT-11 SJ...
If the software is started as a result of a command in the STARTS.COM
file, then it should be possible to ^C out of the command file and
be left in RT-11 without accounts and passwords...
Beyond that, I don't know how one might crack the account/password
info on TSX...

For TSX, just boot the system in RT11 without TSX. Then run the tsauth
program and set any passwords you like. I'm not positive, but ISTR tsauth
doesn't require a password to run it if you're not running TSX at the time.

As I understand it, a baud is 'number of signal changes per
second'. If you use an encoding method which requires a signal
change for each bit, then 9600baud = 9600bps. Another encoding
scheme might only require 4800baud (4800 signal changes) to get
9600 bps across the wire.
In this case, it sounds like your modem uses a scheme which
somehow gets 4 bits across the wire per signal change, so
7Kbaud (7000 signal changes per second) gets across 56Kbps
(56000 bits per second).

RSX Runtime system? Under RT-11? Or on a separate disk?
Passwords on an RT system? Not normally... you may be running
some special software...

Sounds like a couple of DLV11-Js... 4 line serial async cards.

M8043 if it is a DLV11-J...
As for configurating the ports, the console always has to be at
the address 177560, with a vector of 60. The DLV11-J allows one
of the ports to be the console. The other ports are configured
for successive addresses in the range 176500 and up, with the
vectors in the floating range (300-476).
You're going to need to let us know what boards you really have,
and then we can tell you what documentation you'll need to
configure them.
I would suspect, however, that it has already been configured for
the software you have on it.
RT-11 as distributed only knows about one terminal - the console,
at the standard address. To support more than one terminal, you
would have to do a sysgen (system generation, in which a new
monitor is built using conditionals specified to the sysgen
procedure). But remember, RT-11 is single-user, so even if you
have multiple terminals, only one can be the console, and only
the console can initiate programs. Such programs *can* then
allocate the other terminals and control them (such as in the
multi-user BASIC which is available for RT-11)

Okay, I own a computer so of course to everyone who doesn't I'm some
kind of expert (not).
So the other day this guy brings me this 256k Wang, wants me to set
it up for him. Set up to do what? Alright maybe I may have some old DOS
stuff a wordprocessor, spreadsheet, hell maybe I even got a pong game still
laying around. My problem is how do I write to this thing?
Its got one of those old floppy drives with the lever and all (never
used them I was running a Mac before IBM saw the light). The hard drive is
>from the stone age (is this SCSI compatible?) And the mother of all boards
with connections for a network possibly? Probably a mainframe Yuk. Anybody
ever own one of these things? Can anything be salvaged? Is this just an
overgrown typewriter? How am I going to write to this thing without
destroying my computer? Help Help Help...
Here's some numbers: cpu 256kb, two PMO30-b 128k Memory expansion, PMO08 c.g.I (monitor controller?), pm02/022-b Winchester controller,Seagate HD, and of course the standard Wang kb and monitor (RGB I think they called them you know green just green). Everything works even has some old data base software still on it.
