+MrFish Posted August 30, 2016 Share Posted August 30, 2016 (edited) Possible the other libraries were optional add-ons that cost more... Yes, as it turns out, they were all, in fact, modules to be purchased separately. The author of this Creative Computing review talks about it in the sixth paragraph: Going Forth.

Farb Posted September 2, 2016 Author Share Posted September 2, 2016 I suspect these to be (technically) bad dumps with gone-bad sectors in unused areas of the disk: Blue Max (1983)(Synapse Software)(US)[OS-B] Factory, The (1982)(HesWare)(US)[bASIC] M-ss-ng L-nks (1984)(HesWare)(US)[bASIC][OS-B] Picnic Paranoia (1982)(Synapse Software)(US) Protector II (1982)(Synapse Software)(US)[OS-B] Spy vs. Spy II - The Island Caper (1985)(First Star Software)(US) Survivor (1982)(Synapse Software)(US) The bad sector of these dumps contains data but is not read during initial loading of the game: Blue Max 2001 (1984)(Synapse Software)(US) 33/$21 Drelbs (1983)(Synapse Software)(US) 693/$2b5 Thanks to Ijor, we now have good images for Blue Max 2001, Picnic Paranoia, Protector II, Spy vs. Spy II and Drelbs. They will be in the next torrent. We will need to obtain more dumps of the other titles before we can release good, verified images. Quote Link to comment Share on other sites More sharing options...

Kr0tki Posted September 23, 2016 Share Posted September 23, 2016 I just love when an emulation-related issue description does not even name the emulator. Makes it so much easier to help. :-] Quote Link to comment Share on other sites More sharing options...
Shannon Posted September 23, 2016 Share Posted September 23, 2016 (edited) Altirra latest version. Atari800win (ATX version) Atarixlbox (based on atari800 core ver 2.03 and recently released VAPI code added by me). I guess most people would figure I'd only use emulators that can handle VAPI (atx) images. Which limits it to those three and the Atari800 for the MAC. Which I don't have.

+remowilliams Posted September 23, 2016 Share Posted September 23, 2016 So I actually found my kryoflux AND a working drive. Seems I can make ATX dumps once again Or at least for disk sides that have an index hole. That's kind of annoying... 1 Quote Link to comment Share on other sites More sharing options...

ijor Posted September 24, 2016 Share Posted September 24, 2016 Preservation. Gone wrong. Yep, it happens. I have a collection of disks in that condition. Only from Blue Max (probably the worst title in this regards), I think I have a handful completely destroyed. First thing first. Take your time for a very good cleanup of the drive. It is probably very dirty and full with debris. Do not attempt to read anything valuable with that drive before you are sure it is clean again. Try with expendable disks before. I believe I said it already a few times. Many disks cannot be dumped with the default (so called preservation quality) parameters. The usual suspects are disks from certain period by Synapse, Avalon Hill, ICD, and a couple of other cases. Most of those disks simply cannot sustain the pressure of the disk head for too long. I even had a special version of my dumping software for reading those disks. The goal, contrary to the normal, redundant, mode of dumping disks, was to make the disk to rotate with the head engaged as less as possible. 1 Quote Link to comment Share on other sites More sharing options...
+remowilliams Posted September 25, 2016 Share Posted September 25, 2016 Yes the drive is spotless, that was the first order of business on all the disks before this one. It needed cleaning afterward though... This disk was in known bad shape so I went for a limited pass, first revolution it just disintegrated completely. I was not surprised in the least. I would agree that Blue Max was probably the worst ever, I must have had 3 or 4 fall apart on me by just looking at them. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted September 25, 2016 Share Posted September 25, 2016 I need to state something here, because this is very much like a similar situation that I've had to deal with, regarding reel to reel studio audio tape manufactured from the late 1970s through the late 1990s. Let me explain (big long grody technical explanation following): THE PROBLEM: As preservationists would attempt to archive studio tapes from artists from roughly 30-40 years ago, they kept running into a very consistent problem: the magnetic oxide would flake off the tape, and would deposit itself, en-masse on the tape heads, ultimately destroying the head assemblies and requiring replacement. This is literally because of a simultaneous change in the formulation of the magnetic oxide blends used on the surface of the tape, as well as drastic changes in the chemical properties of the adhesives used to bond the tape to the mylar substrate. The simultaneous change of both properties resulted in magnetic tapes with better frequency response (we're talking roughly a 10-15% increase)...but the drastic change in adhesive properties is what bit studio engineers in the arse. Specifically, it was discovered that using a urethane adhesive with short chains was effective at improving frequency response. However, these particular urethane isomers had the effect of being HIGHLY hydroscopic, absorbing water even from the ambient moisture around the tape. Over decades, the stored water keeps the urethane in an amorphous gelatinous state, and thus it's like ripping away jello form the bottom of a glass casserole dish, at high speed. THE SOLUTION: The solution turned out to be very simple: Baking the tape at approximately 130 degrees for 4-6 hours was sufficient to temporarily evaporate the moisture from the urethane, and provide enough time, after cooling, typically a day, to be able to transfer the tape, to another tape, or onto a digital system. However, the process has a cost: it vastly re-accelerates the process of pulling in moisture, and the whole process will have to be repeated again, if one wishes to pull from the same source. THE CONCLUSION: I believe a similar approach can be taken for floppy disks, after their removal from the protective jacket, to avoid the very problems you are describing, but I have yet to be able to test the idea. Perhaps somebody can verify it? -Thom 5 Quote Link to comment Share on other sites More sharing options...
ijor Posted September 26, 2016 Share Posted September 26, 2016 I need to state something here, because this is very much like a similar situation that I've had to deal with, regarding reel to reel studio audio tape manufactured from the late 1970s through the late 1990s. Very interesting. I didn't perform a chemical, scientific analysis. Certainly don't have the tools neither the knowledge. But not sure it is quite the same thing on floppies. On our floppies, it sounds as the problem is the other way around. Not that it becomes too damp, with too much moist. But actually that it becomes too dry and too rough. And according to my experience, it helps a lot to wet the disk surface with alcohol isopropyl just before reading. Also, just for the historical background. In our case, it is mostly about floppies manufactured during a rather small period (a couple of years or so), and usually only recorded by a a few publishers. It is just quite unlucky that covers the golden, and most prolific, period of Synapse. The solution turned out to be very simple: Baking the tape at approximately 130 degrees for 4-6 hours was sufficient to temporarily evaporate the moisture from the urethane, ... I believe a similar approach can be taken for floppy disks Well, besides theory, it is certainly worth trying ... anybody? 1 Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted September 27, 2016 Share Posted September 27, 2016 . . . Baking the tape at approximately 130 degrees for 4-6 hours. . . Remember, that's 130 degrees F or 54 degrees C. 2 Quote Link to comment Share on other sites More sharing options...

Kr0tki Posted October 3, 2016 Share Posted October 3, 2016 My First Alphabet (1982)(APX)(US)[bASIC] rename: copyright 1981 Nope. As the manual's front page says, the APX release is from March 1982. Actually it should be renamed to (1982-03). Quote Link to comment Share on other sites More sharing options...
+DjayBee Posted October 3, 2016 Share Posted October 3, 2016 1:0 Kr0tki But then consequently the Atari version, which currently is named 1981, should be renamed to 1982. It came later and also has the 1982 copyright on box and manual. => 1:1 Quote Link to comment Share on other sites More sharing options...
