You can boot the system in single user mode, remount / as read/write, then
use the passwd command to change the password. Reboot in multiuser, and you
should be ok.

Dropped by a hamfest today. Got a DD11-DK, a RX11 board,
and a Macintosh LC.
Also got my newest and smallest toy yet!
It looks like a large calculator, and it's a little weatherbeaten, but
it's a computer. It's a silver obling piece badges as a "TRS-80 Pocket
Computer". It seems to undestand a subset of BASIC, it has a printer/cassette
interface (as a seperate unit, and the printer ribbon is shot), and acts
like any other TRS-80 I've met so far.
I have no clue as of the capabilities and limitations of this piece -
Anyone got any information? The LCD is cracked (t was dropped) and the case
is pretty beaten, but it seems to work fine. I'm probably going to open
it shortly, something inside it is rattling around.
Anyone else know any more about the unit? This looks neat enough I might try
to scan pictures of it and post them somewhere.
-------
A question for those who might have worked as exterminators putting
themselves through college...
Are there any potential risks to my old beauties by bug-bombing the
garage? I have had enough; I am still recovering from the effects of a
black widow bite I sustained while (stooopidly) reaching inside the main
cabinet of my HP-3000/37 the other day. Not too serious, apparently I'm
not particularly allergic and it was a rather mild bite, but I've felt
like I've had the flu for a few days. My doctor was amused that I got it
fooling around with computer artifacts, though, which led to me possibly
(crossed-fingers) inheriting some nifty old proprietary medical gear.
I'd like to just set off a few foggers in there, but my dilemma is that if
I cover up the gear with plastic well enough to keep the spray out, the
nasty little bastards may survive. Anyone done this? Thoughts?

If you either yank the graphics cards or hold the halt button in
during reset it'll use the MMJ as a serial console.
>It seems like a really nice box

That's M-Bus, not VAXBI.
>(it has Qbus too!),
If you have the FTAM (Firefox Tape Adapter Module), you can only use
QBus devices that can tolerate upwards of 20 microseconds bus latency
(I have a specially modified RQDX3 somewhere...). If
you have the FQAM (Firefox QBus Adapter Module, designed after it
became apparent that FTAM was in trouble) the latencies are acceptable
but the QBus throughput is only about 250KB/s.
Welcome to the magic of write-back cache.

Yes, it will fit. If it was in there, well, then, maybe it really
is the Q-bus version. (Or my memory of TCU vs TCQ has faded...)
For that matter, Omnibus boards fit into Unibus and Q-bus backplanes too...
>I had trouble setting the clock on this system, maybe this is

If the RT-11 "TIME" command isn't incrementing, that has nothing to
do with the TCU - it's an indication that the line time clock (60Hz
for us) interrupt is somehow disabled.
With the board in, does it respond at its standard addresses of
160770 - 160776? If so, then it's installed in the right sort
of system.
You ought to see the value at 160774 incrementing once per second
if the clock is indeed ticking.

It's not a Q-bus board - what you have there is a Unibus clock board.
(There is a Q-bus version, not surprisingly called the TCQ-150.)
I posted Y2K patches to the Digital Pathways supplied RT-11 clock-reading
routines on vmsnet.pdp-11 a few years back, if you want to put this
board to use. Accessing the clock board is very simple; it's four
words from 160770 through 160776. The first word contains the date
(not in RT-11 bit order) as year (7 bits), month (5 bits), and day (5 bits),
the second word has the hour and minute, the third word has the number
of seconds, and the fourth word has the number of clock ticks.
With 100% certainty, you'll need to replace the batteries on the board.

Hi,
Has anyone come across this machine before? It's a rubber-coated pen Windows
machine. Does anybody have any info on it? I just got one at the MIT Flea
today and am having some problems booting it.
Has anyone ever heard of a "Kaypro PC-10"? The Kaypro PC models I am familiar with are the 16 and 2000. Someone is selling a manual for a PC-10 on eBay:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=164605910
My guess is that it is an abortive non-portable PC effort.

VAXarchive has indeed been down for a while, but it will be back!
The IP number of the machine hosting www.vaxarchive.org has been changed,
and there was a problem updating the name servers. It should be fixed
soon. In the mean time you can use the mirror at
http://vaxarchive.sevensages.orgwww.vaxarchive.org is the new name of vaxarchive.ml.org, it had to get
a new name after the ml.org service went away.
I'm glad you mentioned the site, makes me feel I'm not maintaining it for
nothing :-)
Kees.
