This is a good point. I write code, lots of it. I'm a hardware person so
I'm
one of those that really do not see myself as programmer save for I'm forced
to! Also while I do see hardware as art (right brain) programming for me is
mostly mechanical/procedural and IDEs drive me nuts for that reason.
On the other hand, in the last 10 years there have been more lines of code
generated the likely the preceeding 20 years and so on. The need to solve
problems does force this forward.

To me fyi, SLEW is my word of choice for things that have a delta, IE:
any moving target. MS interfaces are clearly slewed over time.
While it must bother some as misuse, I read it as both usages as
one rather funny pun. It is a quagmire and also there are a rather large
collection of goo all adhering to the mess called Windows. Got any Windex?
The idea of a windowing system, thank xerox parc for that, apple and MS
put it in front of people when hardware to run it got reasonable, it was a
hit.
historically "windowing" was the killer idea just like visicalc and easy to
use databases (dbase) that needed to happen to get a lot of computers
on more than desks of computer savy people.

Hi,
I have a pair of 851s in a nice case with power supply.
They are attached to a Cromemco 16FDC in an IMSAI box
with a Cromemco ZPU and an Expandoram 64K board. I'm
using the ROM enable on the 16FDC to drive the phantom
line. There is a reason for these details...
Here is the problem:
#1 Power up the drives by themselves:
At the drives:
5 volt line reads 4.9
-5 volt line reads -4.9
24 volt line reads 23.9
#2 Power up the IMSAI box:
At the drives:
5 volt line reads 1.2
-5 volt line reads -0.9
24 volt line reads 2.6
and (needless to say) the drives don't work. The Cromemco
ROM monitor gives all sorts of errors trying to access them.
#3 Power off the IMSAI box:
(Same as #1)
#4 Power on the IMSAI box again:
At the drives:
5 volt line reads 5.0
-5 volt line reads -5.0
24 volt line reads 24.0
and the drives work fine.
What gives? Does this make sense to anybody out there?
Anybody know where I can find an AC adapter for a Thinkpad 720,
or alternately, anyone who has older 486 Thinkpad(s) for sale *cheap* ?
Thanks.
Bill

I've got two VAX VS4000/VLC workstations, both with 24MB, one with a disk
and one without.
One takes two or three minutes to perform the memory test at power on and
the other takes maybe 20 - 30 seconds. Any idea what could cause this
descrepancy?

When we had to move from my original warehouse in Portland we brought in a 30
Yard dumpster. Now there was stuff on the seventh and the third floors. It
was just too much of a temptation. On a quiet Sunday a television jumped out
a window on the 7th floor, dead center into the dumpster. A huge crash echoed
between the tall buildings of the street. We discovered that plastic likes to
shatter into lots of pieces when dropped from great heights. Aiming from the
seventh floor proved difficult, however. The next item, an old stereo split
the far edge of the steel wall of the dumpster. While the motor and heavy
parts ended in the dumpster much of the plastic littered the street. We went
down and removed the plastic before we could get into trouble.
We relocated to the third floor which had a lot of Wang 22XX terminals. Now
this was much easier. The dumpster was not the small target that it seemed
>from the seventh floor. The heavy weight of the Wangs made for a more
predictable trajectory, not to mention a very satisfactory racket when they
landed in the dumpster. They possessed considerably less kinetic energy and
generally stayed in one piece with pops when the tube blew. Crash, pop,
crash, pop, crash, pop... After all, these terminals were scheduled to be in
the dumpster anyway, what better way to do it, and let gravity help.
In the next warehouse we got in two pallets of copper wire on steel spools.
It proved to be very difficult to destroy the spool yet keep the wire in a
coil. Finally we took all the wire to the roof of our 6 story warehouse.
Since we didn't want the wire to lose form we just pushed the spools off with
little horizontal acceleration. We were right. When the spool hit the
pavement of the parking lot. the ends jumped off the spool. The wire might
expand in an elongated coil but was easy to gather together. The best
solution was to hold the spool out and just drop it. The goal was to get the
spool to land flat on one side. The opposite side would pop off and the coil
would bounce up and down, staying tight. This was lots of fun on another
Sunday in Portland. I have some video.
I believe in using gravity as a tool. However most of these fun ways are
illegal now in Portland. We did most of this 10 years ago. For those that are
worried no collectable computers were sacrificed this way except the Wangs.
Thanks for the URL on the Drop Squad. I enjoyed it.

Hi,
OK I have an 8/i, but now I have a lot of questions; first, where the heck
is the serial number on the dumb thing? The top of the main frame seems to
be the listing for the options and serial numbers, i.e. "KW8I 532," "MC8IA
1877," and "KP8I 774." I know this means it has/had another 4K of memory,
the power fail/auto restart, and the RTC. On the back of the main frame, it
has one more serial plate, though it looks like there used to be another
one. It reads "M26 8I L3213." Is there any way to determine the stupid
thing's serial number or is it there or ??? I have reason to believe that
it's a fairly early machine, since it's a Negibus 8/i, and some of the chip
dates are from late '68/early '69. I'd appreciate not being outbid on the 4K
PDP-8 core stack on Ebay, as I need it to have the full 8K that it once had.
Does anyone have any real docs for the beast they could part with? I mean
originals, yes I greatly appreciate highgate, but since I plan to have a
museum at some point, I really do need the real things. Not to mention that
I don't have the equipment to print a D-size drawing (the module utilization
chart). I also need the trim piece for the top of the rack it lives in (the
old black 6'4" style). While I'm at it, I have no manuals for my 11/34A or
my VAX-11/750..

Ok, so I've got two VLC's and I want to see if I can cluster them over
ethernet. This is a precursor to installing the 3400's to be a local
cluster over DSSI. What document do I start in?
I'm guessing that I somehow need to get MOP running on the VMS system and
to tell it the ethernet address of the other VLC so that when it MOPs for
an image the cluster will respond.

DEC part numbers are 2-5-2 numbers -- two digits, five digits, two digits.
So with this being 3-5-2, it doesn't appear on the face of it to be a
DEC part number. But the board numbers will tell...

Trying to clear some space in the 'Garage' yet again, and so this time are
offering some assorted classic (and some not so classic) Component
Databooks and assorted manuals.
The basic deal: $5.00 each (includes postage in the U.S. - elsewhere, ask)
with the exception of a couple of application notes which are $1.00 (they
are noted as such in the descriptions).
Any not spoken for by next weekend will either make a pass at eBay or the
recycling bin. So hesitation is not recommended... B^}
There are no 'quantities' either in pricing or availability. There is only
one of each item listed. First come, first served...
Payment options: check, (must clear before shipment) or postal money order,
PayPal (if you are in a hurry)
So off we go:

>I believe in using gravity as a tool.
There's an interesting article in the Annals of Irreproducible Research
where (using a suspect extrapolation!) they calculated how many times you'd
have to drop a frozen turkey from an 10-story building to get it fully cooked.
IIRC the title was "Cooking with Potential Energy". The text (though not
the graphs) seems to be online at
