If you want to try Lotus 123, get an HP LX 200 palmtop computer. It comes with Lotus built into the ROM. In fact, the ability to run Lotus 123 was the genesis of the HP plamtops.
One of my gripes about Lotus 123 is that it excelled (pun intended) at losing your work, as it did not ask you to save the file when you quit -- "/Q" would quit the program whether or not you had unsaved work.
Bob??
PS. Re the "what calcularor to get" thread, you can get an HP LX200 and run any of a number of MS-DOS HP calculator emulators on it.
Does anyone in here admire/collect old clocks? I want to get a Standard
Electric AR-2 slave clock (60s style). I fondly remember that model as
the one used at my elementary and junior high schools.

It's still not too hard to find a HP-25. Retrofit the rechargeables and you're set.
But IMHO the true sweet spot is a HP-15C or HP-11C. A set of batteries will last for years.

I have a number of PDP-11 software manuals, processor manuals, a few books & even a few software mag tapes from when I had worked at Digital Equipment. I also have a number of processor manuals & some schematics for DEC System 10 & 20. Would you be interested in them or know someone who would like them?
The system 10 & 20 schematics piqued my interest. If anyone wants to follow up on this, email me off list for contact details.

A PCB manufacturer in San Diego, CA is currently using PDP 11/04 boxes for Advanced Controls Trudrill machines. They are looking for sources for repair, support, and/or replacement parts. They believe that they could also switch to 11/05, 11/24, or 11/34 boxes with the same application. If anyone is interested and able to provide this, email me off-list for contact details.

Not all that "classic" but figured I'd make the offer in case someone
needed pieces or parts. Located near the Chicago area, willing to ship
parts and I highly doubt anyone would want the whole thing. You however
might want HP SCA drive trays (also works in the other HP storage stuff
the same age), scsi/sca backplanes (6 drive slots per side, actually
quite nice drive cages if you wanted to do something with that), power
supplies, proc or mem boards or anything else. It's a mini-fridge sized
multi-proc Pentium Pro server with 12 half height drive bays, 3 power
supplies, etc. One last offer for parts from this beast before I part
it out and scrap it. I'm keeping the basics memory, procs and drives,
but I can be convinced to part with those as well if you have a need.
Nice machine for its time, but the 1kW/hr power use and physical size is
convincing me to get rid of it.
Once again, located in the Chicago area. Crossposted, so first come
first serve and closer the better.

In fact Googlebot is regularly scanning all my ftp sites quite regularly. But I would not classify as usefully return search information.
There are several other bots out there (some of them russian, one of them may be mmnt) scanning ftp sites.
Remember when archie did all this? (Or at least, tried to do all this.)
Oh well, another post that reminds me of all that tinkering I'd like to do but can't due to lack of time right now.
There is a broken Siemens "Hauptuhr" (master clock) HU 10 in one of ?y banana boxes from hell, which formerly did its duty in a school in my district. This is more modern (I'd say 70s if not 80s vintage) unit with a lead-acid battery for backup and a discrete electrical second (or maybe half-second) oscillator driving the "seconds" part of the mechanical work, which in turn actuates a contact to generate "minute" pulses for both the minutes/hours hands of the local dial and the slave clocks. It seems that just the primary oscillator or maybe the seconds actuator is broken, as manually generating pulses via the Set button does advance the hands as expected.
What's more, the device also comprises a loop of, IIRC, 5-level punched tape in a box with, I think, one "character" position for every five minutes in either 24 hours or even seven days, which would usually probably be used to ring a bell for signalling the breaks at the desired times (on schooldays), but could of course also accomodate other functions.
I also do have a kind of slave clock, but not the usual hands-and-dial variety - mine is a digital one which looks like it was from some kind of larger office and works by means of plastic sheets printed with numbers and arranged in a horizontal drum, which flip downward, one per minute, at the actuation of a magnet. Besides hours and minutes, this thing also has a whole calendar with day-of-week, day-of-month and month display derived from this movement, but I've not yet investigated how it deals with the different lengths of the months, i.e. whether it will need manual intervention every two months or just once a year (apart from going into/leaving DST, of course).
Unfortunately some greedy, egoistic creature has pilfered some of the flip sheets, so these will have to be recreated using some kind of plastic stock and painted to match the figure patterns of the rest.
Uh huh, how long will I have to live...
So long, yours sincerely

Well, Xerox was ready in case it ever does!
Supposedly from their Fortran manual:
"The primary purpose of the Data statement is to give names to constants;
instead of referring to pi as 3.141592653589793 at every appearance, the
variable Pi can be given that value with a Data statement and used instead
of the longer form of the constant. This also simplifies modifying the
program, should the value of pi change."

Aarrghh!! Is that what they teach in American schools?? That is *evil*.
My mother once had a teacher who when his pupils were bad, told them to
behave, otherwise he would teach them wrong. In his opinion that was the
worst punishment he could think of.
I am absoutely sure that over here everybody is taught, and always has
been, the difference between natural, real, rational and irrational
numbers, and that pi is an irrational number which can be approximated
by 22/7.
The Swedish school system may have very serious problems, but hearing
this kind of thing makes me very, very grateful that my kids haven't
grown up in the USA.

We have had a successful mission with the Sperry minicomputer pickup.
We dodged the rain showers and successfully loaded a ~5' rack and two
Fujitsu tape drives into two vehicles, then broke for dinner.
Here are pics from today, with more to come of internal bits:
https://picasaweb.google.com/102190732096693814506/Sperry1200Pickup#
The machine appears to be an Arete' 1200, although badged as a Sperry
on the front. Research suggests it is equivalent to a Sperry 5000/80
machine. It is a Motorola 68000-based UNIX minicomputer. This one
appears to have two CPU boards (each with a 68020 processor,) a few
RAM boards for a total of 30MB of RAM, and is missing all of its
storage. The drives it used seem to be SMD interfaced but we're not
sure what it had originally as there are external and internal
connectors.
Two Fujitsu 9-track tape drives, model M2444AC, came with the Sperry
and we assume they were used with it, too. They are heavy!
Here is some information on the Sperry 5000 line. Truly a unique machine!

I don't have any problem with X11 as long as you run a standards-compliant web browser in an X11 window :-). Or an xterm. There's very little today I do in X11 that isn't in a web browser or an xterm, don't you know :-)
X11 just does not satisfy me as a way to define a high-information-content user interface. It's certainly capable of delivering a high-information-content user interface but it doesn't define it.
The web by itself isn't too fancy but couple with Javascript, AJAX, SVG and other high-information-value media of interchange, and boy is it fun to work in! With just a little care, apps scale up enormously and deploy with so little effort on my part.
You might note I left out many common web standards as being high information value.

One of the many potentially great things that died when DEC did was
Modula-3, a language with huge promise (and one that didn't jump the
shark with Wirth (see: Oberon)). There's a small community keeping it
alive, and it's design is still influential (the creator of Python cites
it as a primary influence). Perhaps it's time to give it another look.
Whenever these sorts of "what should the language look like..." debates
come up, as often as not I think "sounds like Modula-3".
The ongoing thread about the origins of C and UNIX have made me
wonder about something I was told years ago:
"UNIX was written as a host platform for C *development* and was not
originally envisioned as the production platform for applications
developed on it."
In other words, the intent was that developers would write code on
UNIX, then port it to an "application-oriented" OS for production.
Is there any truth to that?

Not just bit-aligned data: some processors from that same broad era (e.g. iAPX432) didn't even require that instructions be byte or word aligned.
I think the point folks are missing is that it isn't the processor that defines the standard data types, but the language.
I used to be more condescending towards the attitude that the-whole-world-is-a-stream-of-bytes (having worked with many I/O devices and languages and computers that had far more evolved record concepts) but here i am in 2011 and if I can coerce anything into a stream of bytes - I've got a lot of tools for working with that.

I would hardly call Tony self-righteous. He does have strong opinions
and lives by his convictions, but I have always got the clear impression
that he accepts other people's right to do as they please with their own
stuff. He will try to convince you that you should reconsider, if you
propose doing something which he thinks is wrong, however I don't think
that the connotation
"especiallywhensmuglymoralisticandintolerantoftheopinionsandbehaviorofothers"
of the word "self-righteous" (from dictionary.com) applies. Being
intolerant is not the same as disagreeing and trying to convince people
they are wrong. Intolerance implies refusing other people the right to
their opinions.
Irony does not always go down well either, unfortunately.

This may be a bit off-topic, although the instrumetn in question is
certainly well over 10 years old, it includes a classic microprocessor
(68B09, along with a a 6829 MMU, I've never seen one before), and is
certainly suitable for repairing classic computers...
Anyway, I've been given a really nice toy -- an HP1530D Logic Analyser.
The -D model ahs 16 timing channels (which can be confgured in blocks of
8 as state channels) and a further 27 state channels. HP got a lot right
in the design of this instrument -- the fact that the pods can only be
disconnected after rmeoving a cover plate means that the pods are unlikely
to get spearated from the unit and lost, for example.
Anyway, given it's a -D (and not a -G), is there anyting I should know
about it? Any fun tricks that are not immediately obvious from the

Hi Al,

the other great IBM doc you have been hosting. THANK YOU for your site and
all the great work you are doing!
>> How, exactly, is running something in a web browser "more versatile"
>> than running a purpose-built app with a GUI? WTF?
To me a "purpose built app with a GUI" is the very definition of "vendor lock-in" and "A PC for every function".
To me "vendor lock-in" means "look you have the versatility of running it on this one PC with a mouse and a keyboard and if you want to do it any other way you can pay us for as many copies as you want!".
Whereas a web interface means that the display terminal and application server are now decoupled with a strong implication of scalability up the wazoo. (I know, it's all too easy to make it unscalable, or to embed Windows Controls in a web application and tie the browser to a specific Windows build.) It also implies that multiple applications are accessible simultaneously just by opening more browser windows - and means you don't have to swap 10,000 PC's every time you upgrade the central server.
To me a web interface is way preferable to say a 3270 for filling forms. I know, the hot-shot mainframe app people had some pretty slick user interfaces on the 3270's for some popular mainframe applications. I've seen good ones and I appreciate them. But the vast majority of 3270 user interfaces sucked rocks. I'm not saying there aren't some really sucky webpages out there but custom roll-your-own-GUI-inside-the-web-page design seems to be very much on the decline, thank god.

I used them in exhibits at the Field Museum in Chicago and used one at work for 10+ years without any problems. The track balls are not cheap ($183), but are rock-solid.

Hey all!
I recently followed up on a 4 year old comp.os.vms posting about the DEC
InfoServer Local Area Disks protocol and in the process I managed to get
a copy of the spec as well as a couple of other related ones.
How would I submit these pdfs to bitsavers so they don't get lost to
time?
Thanks!
Brian

Because they think they can make more money by selling the pods
separately? It happens with old cameras as well, the camera is sold
without its special take-up spool, which is sold separately for as much
as the camera itself. And with cars, sell an old car in parts and you
will get much more for it than if you sell it intact.

Kinda like asking "where is 20 mA current loop now?"
They were proprietary in their origins but with open documentation and set a very good standard for how to implement desktop interfaces "right".
ADB's concepts are strong and alive in USB.
Appletalk's concepts are strong and alive in Ethernet. (I know, Ethernet predates Appletalk.)
