This should probably be in an FAQ for RSX.
1. The passwords along with all account information is stored in
LB:[0,0]RSX11.SYS
2. The file is not an ASCII file.
3. Passwords in RSX11M are not encrypted, while passwords in RSX11M+ are.
4. (and this is the important one) to break into an RSX system:
When the system boots, abort the startup script.
(If it asks for the time, press ^Z, if it just runs ahead, press
^C and type ABO AT. (the period is *not* optional)).
Run $ACNT, which is the account managing program.
Change password for a system account (anything with a group number
<= 10)
Reboot, and then log in.
A small explanation:
When the system boots, the console terminal is privileged.
The startup script normally finished by logging out the console.
If you stop it before that, you'll remain logged in at a
privileged terminal.
This can be regarded as a security problem. Normally it wasn't,
since people are not supposed to have access to the console
terminal of a computer. It's locked away inside the computer hall.
If you want to, you can protect yourself against this exploit,
but noone does.

IBM PC-DOS 3.30 could support 4 partitions, one Primary and 3 Extended. The
primary partition is limited to 32MB. Extended partitions can be divided
into a number of logical drives, each limited to 32MB. What limits the
number of ligical drives (beyond the disk capacity) is the availability of
drive letters: the primary partition is assigned to Drive C: (unless you
have more than two floppy drives), and the logical drives get letters from
D: through Z:. By my calculations, with all 24 hard drive letters assigned,
the limit is 768MB.

It does. I have a PS/2 Model 30 (ISA) with a 50MB RLL drive replacing
the original IBM IDE-ish drive. Two partitions under MS-DOS 3.11, one
30MB, one 20MB.
The problem is that there is a small number of partitions possible
(I don't recall if FDISK works the same way under 3.x as it did later),
certainly no more than 4 primary partitions. DOS 4.x came out (as bad
as it was) before 200MB drives were common. By the time "everybody"
was buying "larger" drives, DOS 5.0 was out, solving several problems
with historical baggage.

Hmm... I would expect you'd need a Venix driver for it.
If you _really_ wanted a challenge, you could port Minix to the Rainbow.
Sources are available. Writing a Minix driver for the FDC might be
interesting (not sure how much suitable documentation exists).

The passwords are stored in a file [0,0]RSX11M.sys if I recall it correctley.
Should be a rather small file, just pip it to the printer to see it, it should
be an ASCII-file.
I think that after version 3.2 of rsx11m passwords were encripted, before that,
in plain text. Copy this file to some other media and delete it from your
system disk, After a new cold start you should have an open system. with RUN
$ACNT you can create new user-accounts if you desire.

Anyody know anything about a Lambda Compudialer 729? It looks kind of like a desktop calculator but it's actually a phone dialer. It's not the automatic dialer advertised by those telephone SCAMMERS Compudial. This dates from 1979.
Joe
I Don't know that it is, or at least don't know if the system will
acknowledge its full capacity. CPUs and RAM were pretty small then, and the
BIOS didn't like being pushed for more than 320k. Before asking if the
system can handle it, you might wanna look into the BIOS, and see if *it*
can handle it.

That's a valid question, how big of an drive will the OS's on a Rainbow
support? I'm guessing you might be limited to 30MB, even if you've a bigger
drive in the system. IIRC, CP/M and old versions of DOS only support up to
30MB.

Hey,
I was wondering if someone could help me ID this card. I found this board
in an old Macintosh IIx at a swap meet... When I opened up the case I saw
this big (about 12 inches long and 4 inches wide) BLUE board plugged into
one of the NuBus slots. It has two large chips on it with the markings
Xilinx XC2018-70 PC84C. There is only one port on the card that looks like
a 9 pin VGA or serial port. It has a hand written serial number (1570156),
and a part number of 10008 Rev#2. There is only one sticker on the card
that says "1990 LTI; All Rights Reserved; Ver DPDII 52290H"
Does anyone have a clue? Since the board is blue, I figured that its
probably a prototype of something, maybe a video card?? Thanks in
advance...

To Marvin and Mail List...
You both make correct deductions...
I like this list, and have a lot more fun conversing
about Model I TRS-80's and Tandon Floppy Drives than
wasting time trying to answer drivel, point by point.
And I want to remain welcome on this interesting list.
So, the troll can say or do whatever he likes. Being a
troll, I can now ascribe any posts from under the
bridge to it's proper value.
There's been some news on the Amiga Emulation front.
It seems that on http://www.umilator.com , Bernd Meyer
may relent on his decision never to release Umilator
(A 68k Amiga Emulator that runs on a Linux Kernal
using some technology Bernd created for UAE-JIT, and
some new stuff... Supposedly the fastest and most
compatible emulator ever written.).
He requires a certain number of people to commit to
buying it, as there will be some legal battles with
the people who claim to own Amithlon, which is a
similar project that Bernd wrote code for.
It seems that one person has decided he is the founder
and creator of the software (but only contributed some
minor code that by all reports is buggy and feature
incomplete), and the distributor also claims to own
the software as well.
So far, nobody has been able to substantiate either
paries claims, and Bernie will have to defend his
right to market a product that shares little common
code (some of the code is GPL, so Bernie is free and
clear to use it. And unlike the other parties, Bernie
has a legal licence from Amiga to include their IP in
his product.), doesn't use the same name, and has
significant rewritten code and new features.
But intimidation and threats by these parties have
kept Bernie from releasing it, as he doesn't have the
financial depth to defend a suit in Germany from
Australia. Nor, the desire to be put through all the
stress of a suit.
I guess, he's changed his mind about the stress. And
decided that if the project could generate enough
money, he'd defend his rights to market it on
principle.
So, if you want to see Bernie be rewarded for his
excellent work, and people who want to keep his
product from ever seeing the light of day get their
due for their selfishness, go take a look and register
in the poll for people willing to buy the product once
available.
Supposedly it's done and can be released. Bernie is
just waiting for enough committed buyers so he can be
sure he won't lose his shirt with the court costs when
all the frivolous suits get filed.
I posted that not only would I buy it, I'd also
contribute to a legal defense fund.
Sorry for the long message, hope this of more interest
to the list than troll droppings..

Thanks for the help Tony. These chips might have had some value when I got

Hello,
I picked up an HX-20 years ago, and have finally some time to play with it.
I have a couple questions that perhaps one of you others out there with an
HX-20 could answer.
HX-20 Background:
Cream Color, Cassette Module, NO 16K expansion, HP HEDS-3000 barcode
reader, barcode ROM installed, labeled in Pen BARCODE Z.
Everything seems to work fine. I am trying to get the BARCODE ROM loaded. I
have read all the EPSON docs on their support site. Have not been able to
locate a BASIC tutorial online though.
Questions:
1) Should the installed ROM (NOT a module but inside the HX-20) show up
automagically in the menu?
2) If not, how to I go about loading it into memory?
3) Thoughts on the easiest way to interface the HX-20 to a Win box or
anyone tried a terminal program and a Palm?
TIA

Ahh, That explains why it was allways fussy about signal levels. The data

The lack of boot devices is certainly one reason, but I dont see any memory in
that machine either. The seller advertises a Plessey PM1116, a 16 kw module,
but it's not in the machine.
If you compare the photos, you will see different board-configurations, so they
are actively playing with what to take out and what to leave in.... :-((
This is a very bad sign in my eyes, as they say that they cannot test. If thats
true, why do they swap the modules around ?
Also the far-end unibus-terminator is missing, pointing to a canibalised
backplane and/or expansionbox. Will you be able to find that terminator?
Without that the machine will never run.
Anyway aske a detailed list of all the included modules from the seller.
Further this machine will weight some 50 - 60 kg. At the same weight and thus
shipping cost you can get an 11/34. Thatone will be a lot more fun, as it will
allow you a bigger selection of os's.
The 11/04 is limited to 28 (31 with a trick) kwords of memory, has no memory
management and will therefore never run the bigger PDP11 SW-packages.
If I were to decide, I would leave thisone where it is now, too uncertain at
the probably huge cost of shipping. You better stick to a system that hasn't
been altered after its decommisioning. Its always better if you can talk to the
people that were previousley using the maschine you get, although this happens
seldom.
Finalley, look at the selles feedback, (which is realley good) he's selling
just about anything from anywhere. Don't expect any expertise on the item sold.
