I'm looking at building a personal lighting project possibly using white
LEDs instead of regular miniature bulbs, and as I browsed the Mouser
catalog, I got a whole lot more confused than less...
I'm trying to get the maximum amount of light for current expended, and the
numbers seem to be nonstandard, or at least not enough info is provided... :-/
Example:
P. 217, "Super Flux LED Lamps"
The white one shows at 20mA it will put out 400-600 "Iv (mcd)"
P. 216, "Blue & White LED Lamps"
The brightest white they have is listed as: "2200->3200
"Luminous Intensity" but with no mention of current or value
(mcd? ucd? )
P. 199, "Thru-Hole White LED Lamps"
"Luminous Intensity" ? current would output 1.7->2.3->2.6
(min/typical/max) mcd...
and on P. 206, there's a few colored LEDs output listed as "Foot Lamberts"...
And Digi-Key has these Surface Mount Incandescent Lamps... :-O The look
cool, but how hot do they get? (It's a very small installation area... It's
still an idea I'm forming, but if it works out, it's a *kewl* idea...)
Any good websites w/info on how to figure out how many LEDs I'd need to
make about a 40W (or more) lightbulb worth of light?

What do you do when Life gives you lemons,
and you don't *like* lemonade?????????????
All,
Thanks all for the info. Basically, there's a whole myriad of
cards and monitors for DEC systems, and there's no single tube
that works with them all.
Solution (for me, ymmv) was to get a (cheap! :) multisync monitor
with BNC connectors and sync-on-green capability - I was able to
get a used Iiyama MF8117T (known to US people as IDEK MF8117T)
17" tube. Works like a charm, rock-solid picture on all systems
I could set up for testing. Neat!
I am typing this in a window on that thing, connected to the
VXT2000+ X Terminal, which in turn is connected to my OpenBSD
VAX (4100). Yay!

Speaking of interfacing Selectrics. I was talking to my father about Teletypes the other day and he told me that he had thrown out an old "word processor" (my term not his). He said that it was a desk sized mechanical unit that had a keyboard and mechanical printer along with a paper tape punch/reader. He said that you could type in a letter and insert a pause any place where you wanted to insert unique data such as a name. The unit would save everything on punched paper tape. You could then feed the PT back into and it would type the letter. When it got to the pause it would stop and let you manually type in the name or other data and then it would continue and finish the letter. Does anyone know what these thing was? I think he must have gotten this after I left home because I don't remember ever seeing it. Unfortunately he threw it away several years ago.

My vote is to leave it as it is, ie no tag, please.
I dislike the wasted space in the subject line (and yes I can make it
wider but I choose not to do so because it suits everything else the
way it is, thanks), and there are plenty of other things in the headers
I can filter on. Besides, once a thread has started I can recognise
the subject lines; I don't need tags.
FWIW, I'm on several other lists, either at home or at work, only a few
of which use tags -- and all of those have at some time exhibited the
recursion problem, apparently because some MUAs munge the subject lines
when replying.

Hi
I'm not sure what "Luminous Intensity" means but mcd means
milli-candles and ucd means micro-candles.

This is not so easy to figure. You need to know how efficient
the LED's are, relative to standard bulbs. It seems like I saw
something that said that LEDs were not quite as efficient as
fluorescent lamps but still better than incandescents. If we figured
them at twice as efficient, you'd need 20W's of LEDs. Watts is
just the current times the voltage. You figure this for each LED
and add them all together. LEDs do require a circuit to limit
the current. When you figure your total light output, you don't
count the loss in the control circuit. Of course, for the final
tally, you'll need to include this as well.
When driving a number of LED's, it is better to drive a large
number in series because you only need one current limiting
circuit. The count of LED's would depend on the voltage source
you have available. You'd have the total LED voltage plus
the drop needed across your current limiting cicuit.

If your mail software doesn't do what you need it to do, maybe you
need to complain to whoever sells and supports it, or find other mail
software that does do what you need done. Asking the rest of the net
to change so that you can keep using losing software is not nice.

Here's how that works out here: I set up my mail software to strip the
tag so I don't have to see it. (Clearly, my mail software wins: it
doesn't just do what I need, but also what I want.) Then, when I
reply to the list, my reply's subject does not have the tag. So
messages in the thread can have at least three different subjects:
[cc] foo
Re: [cc] foo
[cc] Re: foo
I'd bet that there's a fourth possibility based on phase of the moon:
[cc] Re: [cc] foo
Do you begin to understand why I think subject tags are not a good
idea?

Yep, that's the problem. The way your message came across out here
in Sillycon Valley was: "I know we've been over this before, so there's
no need to discuss it, just vote to do this and then us folks who cling
to our losing software will stop bringing it up." This is not the way
to win friends and influence people, not that there's much hope of
influencing me on this point.

That's why I vote for no prepending.
I am on some lists that do this, and long discussions (like this list is
notorious for) end up quickly becoming nothing more than a subject line
of "Re: [cc]" repeated over and over.
And no, a smart list server that can handle tags (and thus not insert
them on messages that already have them, or insert them after the Re:)
doesn't always help. Some mail clients/services munge them. And all it
takes is one person in the discussion with an effected client, and the
whole thing gets thrown out of whack.

I'd like to agree with Eric, and also to remind people that this has been
tried on the CLASSICCMP mailing lists, and it annoyed the H*** out of so
many of us that it was stopped.
One major problem I have with it is that it prevents the email software I

Hi everyone,
A number of people have complained to me about not being able to unpack the
tarball with Ultrix V4.20 sources that has been on my FTP site since May 2001.
I have finally found the time to look into the problem and indeed the file was
corrupt. Fortunately, I was able to read my old backup tapes (from Cleveland,
OH, 1999-07-15) without any problems, and discovered to my great joy that this
file was good on my Cleveland machine. (It apparently got corrupted in one of
the turbulent moves from Cleveland to Dallas, TX and then to Orange County, CA.
I don't have any idea how.)
ivan.Harhan.ORG:/pub/UNIX/thirdparty/Ultrix-32/sources now contains *good*
Ultrix V2.00 and V4.20 sources. (Be warned, though, that this machine resides
in my cave which is connected to the outside world through a modem which
usually connects at 31200 BPS, sometimes 28800. Feel free to set up a mirror.)
For what it's worth, I have also put up my Ultrix V4.20 distribution tape
images in /pub/UNIX/thirdparty/Ultrix-32/ult420vaxdist-tk50. They are quite
incomplete, however, as when I had the tape in my hand (at CWRU in spring 1998)
I was unable to read it entirely without errors. Therefore, the V4.00 tape
images in /pub/UNIX/thirdparty/Ultrix-32/ult400vaxdist-tk50 will probably be
more useful for most people. If you have the guts, install V4.00 and then
recompile V4.20 from the sources!

Hello, all:
I bought a STDBUS instrumentation computer off of eBay last week for
$9, and it has some interesting boards in it. Unfortunately, the boards are
mostly older Pro-Log models and information is sparse. I've made contact
with the "legacy" manufacturer who wants $50 per manual for two of the
boards. I found information for two of them on VersaLogic's Web site.
So, here's the list of boards. If any one has original Pro-Log
manuals for these that they can copy and send me, please contact me
off-list.
Pro-Log# Description
7303 DSKY (Display/keyboard module)
7502 Relay output module (8 relays)
7605 Programmable I/O
7806-1 Z80 CPU card (I have copy of VersaLogic's manual)
Other P-L boards from another system I have:
Pro-Log# Description
7805-1 8085 CPU card
7604A 64-bit digital I/O (I have copy of VersaLogic's
manual)
Thanks again for any help.

That doesn't mean anything... up until I was layed off from HP, my

is scheduled to go away at some point. They've been working site

OK, what happened to the things that made Burroughs Burroughs? I worked
there from 1986 to 1989. The B1000 machines were EOL'ed when I got
there and I pretty much had the B1965 at Lake Forest (Orange Co., CA) to
myself doing support for HOSTLINK and GEMCOS. I think Art Sorkin (Mr.
B1000 MCP) had one in Mission Viejo doing MCP support. I never cared
much for the Pasadena machines (the V-Series or Medium systems) and I
don't know when they were EOL'ed. There was a lot of B5000/Large
System/A-Series hardware development after I left, but I don't know what
happened to those machines. Is anyone still commercially running any of
this hardware?
I am not sure which CT machines you are talking about or if you have the
full story on CT. When I joined Burroughs, they were selling a line of
desktop computer called B20 (even though there were B3x machines).
These machines were made by CT and ran an OS called BTOS (a variant on
CT's own CTOS). They were kinda cool because the form factor for each
component was something like a 10" tall by 10" deep by 4" wide box
(called a 'slice') and you added slices together (say, a CPU slice, a
display slice and a disk slice) to make a working computer.
