UK versus US monitor question

by lproven＠gmail.com

So, my UK101 sold for a healthy ?224, which I am very happy about indeed. However, it's to a buyer in the USA and he wants me to split the bundle and send just the computer - he does not want the monitor. He claims that although the computer will run on a 240-to-120V transformer, the monitor will not, as US DC is 60Hz and European is 50Hz. Is this correct? It's news to me. I don't really want to split the package up, TBH - I am not sure that the monitor is worth much on its own. -- Liam Proven ?

Kryoflux (Was: Discferret broken?)

by cb＠kryoflux.com

Hey Sander, > Pah, X-Copy (http://www.youtube.com/watch?v=TCDtnQiZlSc) .... D-Copy > (http://www.youtube.com/watch?v=gUT-gnwpLJ0) FTW! :) Yes, there were many of clones. But I think it's fair to say that many of them just copied the feature set of White Lightning and Fast Lightning which later became X-Copy. The beast of the package was always Cyclone, which with the help of the hardware adapter shifted the read line to the write line. The problem was the missing precomping and refreshing of bit cells, but this was the best you could get back in the day. http://www.youtube.com/watch?v=o2T9qpE6Jhw The inventor of Cyclone, Rich Aplin, actually invented KryoFlux in 2008, about 20 years after the original was made for the Amiga. :-) http://www.youtube.com/watch?v=pOiWGj3A6Eg Enjoy.

Hi Jim, > Not relevant to the archival media question.

This is not about the tools, the formats matter. You need to have well defined formats that are fully documented and open to make sure you can extract the data in the future. I don't know if I'll be using Photoshop in a decade, it matters if I can still open my JPEGs (problematic if you look at the reduction involved) or TIFFs or WAVs or FLACs. It does not matter if you like MS or don't like them. The word format itself is documented, so as long as this documentation is preserved, all is fine. That's why the data we preserve is in containers that have proven to be suitable for over a decade now, they are documented and / or available with source, so people can see how the encoding works.

DEC H960 Rack Connecting Brackets

If you pull off the side panels where you want to do the join (lift up and out), 1/4" bolts and nuts will join the racks together at 4 places. This lacks any beige fillers (which is I think maybe what you're asking for) but it makes two new side panels that maybe can be used elsewhere. Tim.

Hi Fred! >> We don't have anything to hide. We do have eleven years of field >> experience in regard to preservation. > Even "post-millenium" newcomers are very welcome! > > Glad to have y'all involved. > > Thanks for the warm welcome. It's nice to see all the dinosaurs still around. I didn't count in e.g. my years at Cachet (X-Copy, Amiga) in the early 1990s as that was not preservation but banging bits from the source to the target. So if we/I still qualify as newcomers... fine with me. Enjoy!

Hi Dave, answers below. I must admit I was not expecting this in a thread with this title, but I spotted it because I had replied the other day. I hope I can address all your questions. Best, Chris Am 29.02.2012 15:00, schrieb cctalk-request at classiccmp.org: > > I do have a Kryoflux board too ? I got it mainly for testing purposes. > The Kryoflux team does not seem interested in working together with > interested people at the same level as Phil ? Are we? In fact many people working on KryoFlux are contributors. Several people work with the source, and we recently even visited a KEEP (http://www.keep-project.eu/ezpub2/index.php) workshop to discuss and exchange with others, to name just one occasion. I never got a request or proposal from you, but if you have ideas or comments, or whatever to share... please let us know! If you want to browse our website... there is a ton of information we shared (and still do) over the last decade. > their actually-useful > analysis software is very expensive and even dongle protected, > according to the FAQ at > http://forum.kryoflux.com/viewtopic.php?f=3&t=3#p1241 . Yes it is, so are many products. It must admit I don't get how this is related to KryoFlux, or us being interested? I have several products from the same company, some are cheap, others are more expensive. Some come with a dongle, others activate only (yikes!). People that want it can contact us. Some did/do. And some use the software as part of a special arrangement. I really don't see why this is wrong. > The basic DTC > software is closed-source and can be rather temperamental, as is the > firmware. Is it? I'd be happy to hear about quirks. I in fact have many posts and mails that report the opposite. People are in fact happy it works so well. If anything is broken, please send in a bug report. I haven't seen one and I really wonder about the firmware. How would one notice that it's currently "temperamental"? I wonder what this has to do with the status of the source. I'd say it does say nothing about quality. I in fact know many quality products that are not open but I think they are very well executed. Does that mean being open but flawed would be more desireable? > Though Christian says the Kryoflux "never had such a > problem," I have never seen an independent analysis or source code or > anything confirming that. We don't have anything to hide. We do have eleven years of field experience in regard to preservation. The problem outlined by Johannes was a design fault, it's not a glitch. You must not have ambiguity in encoding. Apparently it was fixed lately, a year after release. > I may end up doing this myself. Without > source it's definitely more work to verify it. Let me know how we can help you. It feels a bit odd to read the above when in fact you never asked for anything of the above. How should we know you would want to audit it? > An overview of the engineering of the Kryoflux board indicates it was > designed mainly with low cost in mind. The level buffers on it are > very ESD-sensitive and are not designed for cables (so a long floppy > cable may cause issues), and there's lack of protection overall, > especially in the power supply. I think this is very easy to explain... it was made to be as cheap as possible without sacrificing ingestion quality. We like to make it affordable, and we'd even make it cheaper if we could. We don't want it to be more expensive. The buffers work very well, and we haven't had a single dead one in more than 600 units sold. In regard to protection: One dead board in 600 units supplied, the PSU was broken and just fried the board. We exchanged it. Should I have made all 600 more expensive to cover that one case? That's 599 vs 1. And again: We don't have to hide anything - so I am telling you here in public. > There's no way the current Kryoflux design ever will be able > to image high-RPM media. That's correct. The software could, but the hardware defnitely can't. We never targeted harddrives. We focussed on one specific field of use. And it's working very well. If we'd want to do harddrives or other high-RPM media, we would do another model or product. If these things were cars... we wanted to make something that drives, not something that floats or flies. Just one thing... but very well executed. > As for Linux support: I've seen several complaints lately on the > Kryoflux forums about libusb and glibc issues. Right, you did not want to mention that this is more or less a "theoretical problem"? We offer 32bit and 64bit builds. The 32bit worked for all users (as far as I know, and also on 64bit systems), the 64bit version needed to be refined to make it work on as many distributions as possible. That's just the way it is with binaries on Linux. I am not really happy with that. But on the other hand it satisfies many customers. Just install the software, attach the board - have fun. Buying a bread instead of always baking your own isn't that bad. I wonder how many users will be able to compile a source on Windows or Mac, just to shed some light on the other side of the coin. It's not all black and white. > Take a look: > http://forum.kryoflux.com/viewforum.php?f=3 . Even though they're > somewhat responsive, it's still relying on them for support. I don't get the meaning of this but... if you mean we need a bug report to remove a bug... yes, we do. The wording "somewhat responsive" makes me wonder... people usually get replies the next working day, and even fixes come along pretty quickly. What is wrong with that? To make it better, we have to listen. We do. > There's also the issue of the Kryoflux software lagging behind. > Currently the Mac version (which is what I use) is a few months old, > and lacks many of the features I would like. That is true, you would have to use Windows or Linux. Today. > When I asked about this, > I got brushed away, saying that the person who usually builds that > version is busy. Excuse me, would you mind publishing the answer I gave you as well? I wonder where I did brush you away. I think I was very polite and explained that the Mac port was being worked on. And yes, it's true, our Mac devs are very busy, which is why the team was expanded and a new release is near completion. We welcome everyone that needs an earlier port to step forward and help. Sometimes it's just diffing some files and applying a few platform specific changes. Still, it needs to be done with care and by someone who knows what he's doing. We take quality very serious.
