Vexed that you didn't win mine a week ago? Or did it just go too high? A friend of mine is selling another: http://www.ebay.co.uk/itm/230755691414 Also, he's selling an MGT Sam Coup? that he bought off me a decade and a half back: http://www.ebay.co.uk/itm/230755730713 Lovely machine, the latter - one of the most sophisticated of the 8-bit home micros and I was sorry to see it go, but I really needed the money at the time. -- Liam Proven ?

Update Re: Anyone Having Problems With CHD's RX01 Emulator and Ubuntu 11.10?

Well, no luck on removing the lp driver et cetera under Ubuntu, so I am going to try reverting my Linux distribution, or going to NetBSD for the emulator instead.

DECsystem-20 9 Track Tapes

by rickthornquist＠gmail.com

All - Wow, you guys are great - I already have someone who kindly volunteered to dump the tapes for me. We're going to give it a try tomorrow. Pontus, I'm in Seattle right now and the volunteer is quite close to where I am. I'm not sure of the tape density - the label don't say and I'm not really a 9 track tape guy (my realm is pretty much microcomputers). Zane, if I can get the data off, and it's worth something, I'll likely bundle it on a DVD with the book. - Rick

DECsystem-20 9 Track Tapes

by rickthornquist＠gmail.com

Hi All - I have some old DECsystem-20 9 track tapes that I'd very much like to get dumped. As I mentioned previously, I'm writing a book about Infocom. One of the Infocommies kept some tapes from the early days of the company, circa 1981, and I'd love to get a dump of what's on them. I realized there are services that do this, but I hoping to avoid the cost (which, I suspect, would be out of my reach). Does anyone have a system that could read these tapes and dump the data (or know someone that does)? I'd appreciate any help that you could give me on this. - Rick

old == worthless.

by cclist＠sydex.com

Yeah, eBay seems to be full of this kind of thing. I won an auction for some minor stuff a couple of months ago. Silence, then a note >from the seller saying that he didn't notice that the auction had closed--followed by a note saying that he dropped the item and the plastic case had cracked. When I asked him to send the item anyway (I wanted the guts, not the case), he said he'd thrown it away already. Funny thing is that the item had a metal case... I tend to trust the Chinese sellers more than the domestic ones, all things considered. --Chuck

You obviously never worked with me or anyone else in our organisation. But obviously the fact that we are commercial qualifies you to make any assumption regarding my (our) work ethics. Would it be fair to say all open source is crap because the tool I relied on has been discontinued? Why would any assumption qualify you to criticize what we do? What you say is: A green man cheated me. All green men will cheat. Note that green was chosen on purpose. If anyone reading this is green please accept my apologies. Many customers work directly with our head of development for very specific problems and usually we deliver solutions pretty quickly in a couple of hours or days. Apart from that we even publish the board schematics. You could build your own board and use our software for free which means I don't get a single cent from you yet I would still try to support you if possible.

I only outlined why being commercial is good for the path we've chosen. We can even afford sending someone over, like we did several times in the past, to help with setup and give a comprehensive hands-on lesson. We also can afford donating free boards and software to certain institutions because others subsidise them. What I said was that someone that gets paid will help you solve your problem and try to add whatever awkward format is needed to make you happy. I see nothing evil in that, because there aren't many volunteers around that will do this. > Quite simply if that's your attidude I do not wish to do business with you. Again, you never worked with us. How insulted would you feel if someone judged about you in public, without ever having worked with you?

gluing '60s plastics

by jules.richardson99＠gmail.com

I'm not sure how much variety there was in the plastics available in the late '50s / early '60s, but I've got a plastic part here from that era[1] which needs sticking back together - is there any particular type of glue that I should be wary of? I just have memories of those plastic model airplane kits way back, where certain types of glue would dissolve the plastic, and I don't want to have that happen on an unobtanium part... It's probably one of those things where there's no way of knowing - but I figure it doesn't hurt to ask, and it's the sort of thing where if there is a right answer, I expect that someone on this list will know it :-) [1] OT; actually the platen knob from an old Smith-Corona typewriter. cheers Jules

VCF East 8.0 update

by evan＠snarc.net

Cctalk'rs, Here's a big update about all the things happening with the Vintage Computer Festival East 8.0, May 5-6, at the InfoAge Science Center in Wall, New Jersey. So far we're up to three "celebrity" lectures: Dr. Thomas Kurtz, who co-invented BASIC; Dan Kottke, of early Apple fame; and Bil Herd, of Commodore 8-bit fame. There's also a lecture by Dr. Kent Lundford, who'll teach us the history of analog computing, and there are two more still to be announced. This year we have ** SEVEN ** technical workshops: chiptunes music, software restoration, intro to minicomputer care/feeding, intro to Commodore 8-bit maintenance, into to Apple II maintenance, intro to S-100 zen/innerworkings, and Build a Vector Graphics Kit (the latter is a separate ticket.) So far there are 14 exhibits. We expect around 25 total. There will be a book sale, consignment, food, museum tours, prizes, vendors, etc. In addition, for the first time, we're having a few company sponsors (beyond the usual ones: MARCH, VintageTech, InfoAge Science Center.) The new sponsors are: - Eli's Software Encyclopedia - sponsoring our t-shirts - Western Design Center - that is MOS 6502 co-creator Bill Mensch's company - they're donating 20 autographed chips, which we'll sell for a modest price - Trenton Computer Festival - distributing VCF East fliers to all of their attendees - Vintage Computer Forum (can I say that on cctalk?) - running banner ad for us Bottom line, this is going to be one of the best VCF East shows ever. You'd all be fools to miss it. :) Tickets, as always, are sold at the door for just $10/day, $15/weekend, and free for kids.

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?)

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.

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!

Discferret broken?

by cb＠kryoflux.com

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.

KA694 FEPROM

by vcomp99＠gmail.com

Hi All For some time now, I'm a happy owner of a VAX 4000-705 system. Unfortunately, it came with corrupted firmware, and I don't have replacement KA694... In 'KA694 CPU System Maintenance' I found information that there were FEPROM updates distributed (AFAIK it was called Firmware Update Utility). Can someone on this list point me to a source for that? Or at least the firmware image alone? TIA, Piotr

FREE: Old BYTE magazines - some de-spined

by tosteve＠yahoo.com

I have been scanning and OCRing BYTE magazines, and so far have a stack two feet tall of magazines which have been de-spined with a large paper cutter. Dates are from 1978 to 1987 - not all issues are present. They are free to anyone who wants to pick-up or pay shipping. They are in southern California, Orange County, 92656 I have half as many which have NOT been de-spined, and are intact - someone else has already scanned those issues, so I won't cut up mine, but will still give them away - nothing earlier than 1980 though.

Discferret broken?

by cb＠kryoflux.com

Hi Johannes, I can assure you there has never been a problem like this with KryoFlux. Our devs work in software engineering for large companies (e.g. console hardware and games, chances are you already own a device that has code made by one of us) and are trained to the latest standards. Even dumps made with the very first public beta are valid in regard to data integrity and there is no need to redump anything. There are hundreds of units out in the field, some at large institutes and libraries, where they are being used daily. It's a device made by preservationists for preservationists. For the record: KryoFlux' counters are 32 bits wide. This is no hardware limitation, it was just chosen as sufficient, but we could as well move to 64 if needed. I would recommend our forums at http://forum.kryoflux.com/ which should give you an impression about user satisfaction. We recently added ADF writing, with more formats to follow.

Slowest-seeking floppy or hard drive ever made?

by alhartman＠yahoo.com

I remember taking a copy of NewDos 2.1+ , and an issue of 80-Micro to my local Radio Shack and using their Model I to apply zaps to the OS to speed up the boot and step speed. The store manager thought I was crazy, but it worked great! There were also zaps for TRS-DOS 1.3 which I applied to a copy of that, and made copies for the store. They gave out the faster TRS-DOS to all their disk drive sales as a way to enhance the sale. By that time, the drives were all Tandon TM-100's and could easily handle 12ms stepping. I think I also applied the 40 track patch as well.

IIRC, NEWDOS/80 allowed the step rate to be changed on a per-drive basis? using the PDRIVE command.

ZAPs (patches) to change the step rate globally.|

Slowest-seeking floppy or hard drive ever made?

by tom94022＠comcast.net

I don't know what was the slowest, but I suspect u can get by with what was the slowest defacto industry standard as default and not worry about anyone who was faster. As I recall Shugart dominated the 8 and 5? inch FDs and they were not buffered. So your step rates from their specs are SA800 ? 8 msec SA400 ? 40 msec SA400L ? 20 msec I believe most of the 3? did use buffered seek and I would get the Sony spec, not the first Sony but the one that complied with the MIC standard cartridge spec. Sony may have adopted the Shugart spec, which was: SA300 Unbuffered ? 6 msec SA300 Buffered ? 50 usec minimum period; 1 usec minimum pulse width The SA1000 8-inch HDD from a secondary source apparently can accept buffered pulses at a 1.0 u sec min spacing. The ST506 OEM manual is at Bitsavers; it was unbuffered only at 3 msec minimum period, 10 usec minimum pulse width. (there was a hidden internal second pulse generated at 2.8 msec) The ST412 specification [Apr 82] was one Seagate buffered mode implementation that most everyone had to follow ST412 Unbuffered ? 3 msec ST412 Buffered ? 25 usec minimum period; 200 usec maximum period, 2.0 usec minimum pulse width Microprocessor utilization on the ST412 adds the capability of capturing and storing up to 305 step pulses. The controller may burst pulses to the 412 and they will be accepted until 1) time after last pulse exceeds 200 usec or 2) 305 step pulses are received. At the occurrence of either of these conditions, the ST 412 microprocessor will stop accepting step pulses from the controller and will begin issuing them to the stepper motor. Depending on the length of seek, the microprocessor will select the optimum algorithm. Any pulses issued at a rate between 200 usec and 3 msec may be lost. Note the subsequent ST212 (Apr 84) has a buffered spec of 5 usec min, 500 usec max with a 2 usec min pulse width. So I would set my defaults Unbuffered FDD seek ? 40 msec Buffered FDD seek ? not supported Unbuffered HDD seek ? 6 msec Buffered HDD Seek ? 25 usec period with a 2 usec pulse Good luck Tom > From: classiccmp at philpem.me.uk > > Hi guys, > > Does anyone know what the typical range of floppy and ST506/ST412 drive > track-to-track seek rates is? > > I'm finding myself having to modify the seek logic in the DiscFerret to > accommodate the Seagate ST-277R RLL drive, which requires that > buffered-seek pulses be spaced between 8 and 200 microseconds apart.

Slowest-seeking floppy or hard drive ever made?

by classiccmp＠philpem.me.uk

Hi guys, Does anyone know what the typical range of floppy and ST506/ST412 drive track-to-track seek rates is? I'm finding myself having to modify the seek logic in the DiscFerret to accommodate the Seagate ST-277R RLL drive, which requires that buffered-seek pulses be spaced between 8 and 200 microseconds apart. Any more than that and it assumes you're doing a 'slow' seek at 10ms per step. At the moment the DiscFerret's step rates are set up in 250us intervals, with an 8-bit divider register. Seek rates can be between 250 microseconds and 64 milliseconds in this configuration. Feeding the ST277R the 250us step pulses... really screws it up. The drive deasserts READY and SEEK-COMPLETE and seems to freeze up completely. Hardly unexpected... If I change the seek clock to 125us, I get a minimum of 125us and a maximum of 32ms using the same divider. Is 32ms likely to be enough for even the slowest drives? Out of curiosity, does anyone know what the slowest-seeking floppy drive or MFM/RLL hard drive ever made was, and what its track-to-track seek rate was? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Perhaps studio sync sources were derived from mains power at one time purely as a method of picking a reference to use so that there would be minimal picture roll when transmission output is switched between different sources? Maybe this was found to be counterproductive when large changes in load caused momentarty variations in frequency even though the electricity producers worked to average these out in the longer term? (I don't have any guesses as to what might have been used for a line sync source.) If a three phase grid system is in use with individual receivers normally connected to single phase supplies derived from it and having no choice as to which phase they ended up getting powered by, it would seem to be rather more difficult to attempt to use the power supply waveform as a sync source for reception than to use the sync pulses present in the transmission.

Discferret broken?

by schontman＠ymail.com

Hello all! I have been reading this list some time now. I have a Atari 8 + 16bit collection with hundreds floppies 5.25 and 3.5. I followed the post here about disk imaging and have seen Discferret and Kyroflux. Both look good to me but I use Linux so like the idea of getting a Discferret because its open source. However I found: http://www.fpgarelated.com/usenet/fpga/show/105048-1.php To me this looks Discferret has a problem with either race condition (pulse lost) or ambiguity (two encodings meaning same) and to me this looks this problem is valid for all dumps already made. I talked to other guys from engineering classes and one suggest using 12bits (instead of 8) for counter but this would mean having to few RAMs on the board. Does that mean to better not get a Discferret? Has anyone heard of problems with Kyroflux? Want to start making images soon. Greetings -- Jo

12k-Zapple-BASIC commented

by holger.veit＠iais.fraunhofer.de

Hi all, several weeks ago someone asked for a Z80 BASIC, and my recommendation was the 12K Extended BASIC from TDL. I got several offline queries where to obtain this. I myself knew of a hex dump in a German Book (published there for academical and amateur purposes "because the company does not exist anymore"; the book was >from 1982). Under this premise I disassembled the hex dump and commented (almost) all code. I'll make this commenting work available to anyone who is interested. I don't publish it on a web page (I don't think I need one), but since the disassembly and my comments are CC-BY-SA, anyone else may feel free to do so. Send me a request offline to receive a ZIP file (86k) with the listing and the hex dump. -- Holger
