Does anybody have a Visual 1050 with hard drive setup? I am looking for any doc/pointers on how to get a hard drive configured under CP/M for this system.
Thanks.

Indeed. They are probably perfectly good for photometric applications
too, where it doesn't matter if it takes some time for the cell to
adjust to the illumination.
And as far as environmental issues are concerned, it would certainly be
much better to get rid of CFLs. There has actually been some coverage in
the news here about CFLs being thrown in glass recycling containers
instead of being handed in as toxic waste (there are reasonably easily
accessible places that accept toxic waste everyhere here as well, but
nowhere near as many or as accessible as glass recycling containers) and
causing problems at the recycling plants. LED lighting is being promoted
instead. So far, there has been no discussion about environmental issues
with semiconductor manufacturing...

I'm not a UNIX expert so I must have misunderstood; you mean UNIX cares
about file extensions after all and I can't name a UNIX executable
"your_win.jpg" ?
At least the modern DOS equivalent (which is what we're talking about,
remember?) *does* show the all-important .EXE in the file name, as will
Windows if you've enabled it. How does UNIX warn me at a quick glance?

If they had successfully built in obsolescence, then all the parts would fail at the same time.
The US big 3 automakers to their credit did a pretty good job with this for a long time. Yeah, cars in crashes still had good parts to pick over in a junkyard, but by the end of a cars natural life there really wasn't an awful lot left to pick over.
Not that I'd wish a 1974 Dodge Monaco on just anyone :-)

I just saw your message about CMC which was the company I founded in 1968.
I had no idea people other than I ever thought about it anymore. I can help
with information with anyone who is interested.

CdS cells have quite a few problems that have made them obsolete for
photographic purposes: temperature dependence, slow response and memory
effect. They need a significant time to adjust to a different level of
illumination to give a normal response. The response becoming non-linear
with age has also been reported. For a long time cameras have been using
silicon photodiodes instead.
As an example of the memory effect, the manual for a Durst darkroom
exposure meter, which I have just been given and which uses a CdS cell,
says to illuminate the CdS cell immediately beneath the lens of the
enlarger for 15-20 seconds before making a measurement.
They do work well all the same, most of my cameras that actually have an
exposure meter use CdS cells. And they seem to be easily available.

I was looking on ebay at pictures of Balltimore. Lo and behold I saw
something the Classic Computer folks would appreciate.
See ebay item 260916992297
It is a picture of an actor, but who cares, it's the background that
caught my eye.
I figure there are three classes of "cheap" for raised flooring systems:
- it's new and on sale
- it's used and removed/reclaimed from a decomissioned data center/machine room
- it's used and sitting in the existing machine room and you come pull
it out so they don't have to deal with it
Ideally I'd like to pick up something for free, because this is not a
high priority item for the museum. It's more in the "nice to have"
category. It would make it much easier to supply power to exhibits in
the middle of a large open area because I could run power and data
cabling under the floor.

I'm thinking of thinning down my PDP 11 collection a bit and have a nice PDP 11/35
unit which may be of interest. This is a collection only item in Yorkshire. This is in
good condition and fully functional. It is fitted with the max memory 128KW I think,
and the MMU. I also have the incredibly rare FPU for this unit, but its not fitted or
tested. Also available with the unit, three RK05 drives with disks, cables and the
driver cards (which are fitted to the 11/35). Other spares, parts available too including
a spare CPU set (minus the MMU and FPU).
This is a very tidy unit and as I say its fully functional, powers up cleanly, and even
has its original key. Fitted with a UK plug (European voltage) and can be powered from
regular mains.
Email if interested. Sorry no postage on these units, I cant even lift them never mind
post them :)
Hello.
I have a nice DG One portable computer; it's the 2T version, and appears
to be fully working.
I doesn't have however manuals nor original OS disks for it, so I'm
asking if someone has something to share.
It would be very interesting to find also copies of the CPM OS disks.
Thanks

Why?
What is so terribly wrong with using the file's _name_ to describe the type
of data a file represents, so that those "humans" that you seem to disdain
elsewhere can also know and work with its type, not just the computer?
Always sad to see that in a community one would expect to be eager and open
to explore different and perhaps even better ways of doing things, this
sort of discussion so often is mostly just defending the status quo and
_arguing_ over DOS *versus* UNIX, Win vs. Linux, Apple vs. PC etc., even
sometimes to the point of insulting and name-calling, not to mention the
all-pervasive disdain and contempt for those unwashed [L]users 'out there'
whom all this is ultimately actually for and who indirectly pay most of our
salaries.
We are all in the same business/hobby after all and surely there are better
ways to spend our precious time...
But alas, it has ever been thus...
BTW, I think this quote from Ritchie himself sums it up perfectly:
"Unix is simple. It just takes a genius to understand its simplicity."

I'm looking for a binary editor (platform doesn't really matter) that
can take blocks of bytes (or bits), shift them right (extended shift,
carrying bits throughout the entire block, not just shifting things
on a byte or word basis), XOR, AND, OR with a repeated value (i.e. 12
means 12 12 12 ...), modulo add or subtract, etc.
Anyone know of such a thing? Most binary editors I've seen are very
weak in the area of binary data manipulation.

Hi,
I ordered some additional SCSI to IDE/SD prototype boards.?
The project has a working design (so far) and some preliminary software.
If you are interested in a helping to develop a completely free and open
design please contact me.
http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=MINI%20SCSI%20t
o%20IDE%20prototypes
This project uses the older style technology consistent with the rest of the
N8VEM style boards for easy construction and customization.
While I concede there are many paths to designing a SCSI-1 drive replacement
this approach has merit and has shown some real progress.
What we need is some additional help to get the project finished so it can
be offered to the vintage/hobbyist community as a means to preserve
computers or other devices which rely on SCSI-1 drives.
Thanks and have a nice day!

Hallo Herr Eichberger,
vielen Dank f?r Ihre Nachricht und Ihre Angebote.
Ich merke das vor und melde mich gegebenenfalls.
Selbstverst?ndlich stehe im Gegenzug auch ich zur Verf?gung, wenn sich in meinem Einzugsbereich etwas anfindet, was f?r Sie von Interesse ist.
Im ?brigen trifft sich das sehr gut, denn wir besuchen etwa einmal im Jahr Freunde und Verwandte in ?sterreich und Tschechien und fahren dabei die Strecke Passau - Linz - Wien - Drasenhofen oder umgekehrt - da l?sst sich ein Treffen bestimmt einmal einplanen.
Die Computersammlung am Universit?ts-Rechenzentrum in Erlangen, wo ich einige Zeit gearbeitet habe, besitzt ?brigens einige pdp-11 Rechner und hat evtl. vor, einen davon wieder in Betrieb zu setzen. D?rfen wir in diesem Fall auf Sie zur?ckkommen, wenn wir dann auf der Softwareseite einige Fragen haben?
In meiner eigenen Sammlung habe ich bisher von DEC ?brigens "nur" zwei microVAXen und einen alpha-Rechner, die auch noch auf ihre betriebsf?hige Wiederherstellung warten.
Mit freundlichen Gr??en

I remember we used something of that ilk in the late '80s or early '90s to support one of our products. However, specifics have fallen off the rear of the table of my mind.
Currently, I've been using SoftIntegration's "Ch" <http://www.softintegration.com/products/chstandard/>, an interpreted, C-enhanced, scripting language which works quite well across the OSs I use.

We just rescued a system just like this from another news paper, this
one in central New Jersey.
A gentleman somehow affiliated with the paper had been holding onto
it all these years. It's presently at our museum in Wall, NJ
(Mid-Atlantic Retro). I don't know if anyone from our group took any
photos, but many of the same components.
