so wait, how much vacuum would destroy something? I have a few things
sealed in Foodsaver bags, is this enough vaccum to do damage?

Good tip. Another is that SYSGEN under VMS can also do this. Check the
HELP if you are curious.
Yet another is FLOAT.CMD, which comes with the DECnet distribution of RSX.
And I also have a program written in C from I don't remember where,
which allows you to figure out the same information.

And for the curious of mind, the same from FLOAT.CMD:
. at du:[200,200]float
Determine the floating CSR addresses for your UNIBUS or Q-BUS machine.
Type in the number (0 to 16) of devices for each device on the system
(<RET> = 0). After you have typed in the number for the device you
are interested in, type <ESC> to avoid having to go through the rest
of the list.
Q-BUS machine? y
Number of DUV11s on system:
Number of DZV11s on system:
Number of VMV21s on system:
Number of VMV31s on system:
Number of RLV11s on system:
Number of RXV11s on system:
Number of DPV11s on system:
Number of DMV11s on system:
Number of RQDX1s on system: 2
Number of KMV11s on system:
Number of DHV11s on system: 1
RQDX1 172150 (Fixed CSR)
RQDX1 160334
DHV11 160500
(It's obviously missing the DELQA and TQK50)
And from SYSGEN.C:
.run sysgen
Type device names one per line, optionally followed
by a comma and a repeat count. Finish with EOF.
rqdx3,2
delqa
tqk50
dhq11
sysgen: DHQ11: unrecognized device name; ignored

RQDX3 760334* 0300*
DELQA 774440 0120
TQK50 774500 0260
DHV11 760500* 0310*
CSRs and vectors marked '*' are in floating space.

I don't remember all the details. I do remember that there is a cable
with a yellow stripe on pin 1 and another version of the cable with a red
stripe. If you install the wrong cable (can't remember whether it's red
for yellow or yellow for red) the eject motor does indeed run
continuously.
It doesn't seem to damage the drive; I never let it run more than a few
seconds. So it's easy enough to identify and correct.

Hi guys,
I'm building some hardware that spits out debug info on a regular basis,
and I figured it'd be useful to have this data graphed on-screen. Making
it keep track of the last "N" samples and draw them wouldn't be hard,
except adding an LCD display is out of the question (takes up too many
I/O pins).
On the other hand, I have a perfectly good serial port which runs at a
decent rate of speed (115200 baud), and Xterm can emulate a Tektronix
4014 vector terminal. Perfect... except I can't see an easy way to tie
Xterm to a serial port instead of having it run an application.
There's nothing in the manpage (admittedly I haven't read it all, just
grepped it for a few obvious terms) and 'apropos' isn't finding anything
useful. I've been told that tip(1) on BSD will do what I want, I just
can't find anything similar on Linux...
Thanks,

If anyone is interested in an empty TI 960B chassis for the cost of
shipping, please contact me offlist. Includes only the frame, motherboard
and power supply - no front panel or boards. Even so, it's still big and
heavy so local pickup (near Dallas Texas) will save some money.

I finally got around to taking some photos of the warehouse where my
collection is stored (along with my friend's arcade game collection
and a computer recycling outfit). Most of my stuff isn't really in
good "show" condition right now as I'm trying to organize my friend's
arcade machines and my space is temporarily filled with some of his
overflow stuff to make holes so I can move machines around. At any
rate, you can get a good view of my Tektronix storage tube terminals
and my wall of sgi. Also, there are some photos of the Eve cabinets
for Jos Dreesen. Sorry, just one side of the exterior of the cabinets
for now, board photos to come later when things aren't so cramped.

All,
I have a DECStation 5000/240 and a couple of Storage Expansion boxes I
would like to pass on to someone with more time and space than I have.
The equipment is currently in Cheltenham, UK. I do a fair bit of
driving around the country so I *may* be able to deliver.
Thanks.
Simon

Free if picked up in Northwest Arkansas. These came out of VAX-11/780
systems, so have the 11-03 in its little box and the floppy drive in
its awkward mounting and the terminator and boot ROM is on a big VAX
