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.

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... /Jonas

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.

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.

I beleive that all CdS LDRs > are not RoHS compliant ;-(. This doesn;'t affect home constructios (at > least not in the UK), it does matter if you're going to use them commerially. 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. /Jonas

wanted: raised flooring for cheap

by legalize＠xmission.com

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. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

FS. PDP 11/35 + RK05 units in Yorkshire

by silvercreekvalley＠yahoo.com

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 :)

Data General One: searching manuals and disk images

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 Andrea

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...

ISO: Binary editor with bit shift/complement, etc.

by cclist＠sydex.com

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. --Chuck

SCSI to IDE/SD bridge project

by LYNCHAJ＠YAHOO.COM

[resending message as ASCII only due to severe HTML mangling of URL] 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&param=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! Andrew Lynch
