Kryoflux - a reaction from a potential new customer

by dave12＠dunfield.com

>On another mailing list that I am on, someone was expressing the >desire to retrieve data off some old BBC Micro floppies to see if it >would be possible to get some of the software running on a Raspberry >Pi. They do not own any machine with a floppy interface. My BBC's don't have drives, and I don't have any software disks - so I don't have a way to test this ... but ... According to the all-knowing google, the BBC disk system used an Intel 8271 and later an WD 177x controller - the 8271 does IBM 3740, and the WD is certainly capable of it (so hopefully they kept the format the same). So it seems to me that there is a reasonable chance that these disks could be read with ImageDisk - granted he'll need a DOS/floppy capable PC (or a friend with one), but it might be worth a try. Dave PS: If anyone does read BBC disks, I'd love copies for the archive. -- dave12 (at) Dave Dunfield dunfield Firmware development services & tools: www.dunfield.com (dot) com Classic computers: http://www.classiccmp.org/dunfield/

Seemingly complete DG S/230 16 bit Eclipse system

by chris＠mainecoon.com

On ebay, item 230754098992. The seller is somewhat clueless about what he has (it's an 80s machine, not 60s) and is probably missing a zero from his estimate of what the thing weighs, but otherwise it looks complete and in good condition save for a couple of rack filler panels that look like someone drove into them. From the photos it looks like two 1600BPI drives, a couple of 8" Fuji SMD drives with some sort of emulating controller and three IAC-16s or equivalent. No affiliation with the seller, save for the fact that I'd be bidding on the thing if I could figure out how to get it from VA to CA. -- Dr. Christian Kennedy chris at mainecoon.com AF6AP http://www.mainecoon.com PGP KeyID 108DAB97 PGP fingerprint: 4E99 10B6 7253 B048 6685 6CBC 55E1 20A3 108D AB97 "Mr. McKittrick, after careful consideration..."

Hello. I acquired a Dilog DQ619 Qbus card for PDP11. It is a Floppy SA450 interface with RX02 emulation. I'm searching for a manual, or for some info about jumper configuration and general usage. Anybody has this board? Thanks Andrea

SPS licence

> The licence I read (on the Kryoflux website llast week, probably in the > PC distribution) seemed to define 'Technology' as includign the > documentation. And I feel that this could well include the file format. > That's why I sent the link along to the file format description that's on Jean's site in France. It's for sure not covered by the licence and it's even endorsed by us (we gave Jean the info needed). Apart from that, I will make sure the licence will exclude the format in the future. > I accept it's not your intetnion to limit the file format in this way, > but I think the licence needs work... > Indeed. I jumped aboard in 2009, and many things have happened since then. You can't change things in a day.

Nowehre is it clear to me that the file format > does not come under this As said earlier, no one here wants ownership in data ingested with the device. You can take my word for that and it will be addressed. I am not making this claim to sell anything to you, but because it matters to me.

Things available in Minneapolis?

by jules.richardson99＠gmail.com

Hi all, Just wondering if anyone knows of any vintage equipment available in the Minneapolis area? I'll be heading down to Bloomington this coming Saturday for a few days, and - for once - will have a van with me which will have a bit of free space inside (normally on such trips it ends up full to the gills with other stuff :-), so I could potentially pick something up on the Sunday or Monday to bring back with me. I am actually picking up a QX-10 on the way down there, but I think I'll have a bit more room for something else so long as it wasn't too big/heavy. cheers Jules

Hey Tony, no it can't. Jean did not use "the technology". He got the information from us and never signed an agreement, NDA or whatever. If you look at the current rel. 2 of KF 2.0 b9 for the Mac you will find that I already made a quick fix to the definition of derivative works (threw out the formats). This will be refined even further.

Apple 1 programs

by sellam＠vintagetech.com

I just re-discovered a directory on my server that has Apple 1 or at least 6502 programs in hex dumps and also object code that was apparently "assembled" using a PHP script I guess I wrote at some point in the past that I also found in the directory. I've long forgotten from where they came, and what they are doing there, but while they are there I figure other people should download them, especially Apple-1 tinkerers. Have at it and have fun. http://siconic.com/a1/ NOTE: the files that have a .xxx extension are binary files. -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

Discferret broken?

by cb＠kryoflux.com

> I will answer in brief. Hi Dave, so do I. now I think I understand the issue. It's about the (old) open source discussion and daring to ask for money. I really don't feel like arguing against that. What I know is that people deliver good work when they are motivated. I see no evil in the fact that people get paid because this can be a very good motivation. It also enables you to spend money for things that make the product better.You also can spend the money to train programmers so they use latest techniques and don't do beginners faults. I don't speak for everyone involved, but: I scan artefacts with a commercial scanner software, I process images with Photoshop, and I use TotalCommander to organise files and put them up on the FTP. This does not mean the images scanned and archived are less preserved. I would not want to exchange a single tool. I enjoy using them every single day.
