  1. How hard did you wipe it? If the ProDOS filesystem and boot sector are still intact, just copying PRODOS to it is about all you need. If the filesystem is intact and size information is still there but everything else is gone, a dumb formatter like ADTPro can smooth it over (but for arbitrary disk sizes, it needs to be able to ask the OS what size it should be). If all else fails, a ProDOS utilities disk has the formatter of choice.
  2. The solution in these cases is to "bake" the cookie a little bit - one of those toaster ovens does wonders. I find most Control Data 5-1/4" disks I run across are in this camp... gooey binder that rubs right off of you're not careful.
  3. Have you looked at https://www.kansasfest.org/? Or looked at the session downloads, recordings, or...? I've never been myself, but I wouldn't reach the same conclusions as you just based on a cursory glance at that site.
  4. An accelerator doesn't make tons of sense in a gaming context. Unless you're playing Akalabeth and you want to speed up the maddeningly slow drawing. :-) Jorma makes an interesting point in his article that you can actually use it to slow a game down that is moving too fast for you (though that would also slow down the controls, which might be just as maddening). Otherwise, for any other compute-intensive operation under the sun - it makes tons of sense. I/O on the Apple II is famously tied to 1MHz CPU speed, but any other task benefits: word processing, database, whatever. Even disk transfers are zippier because data still has to move around internally... it'll be 1MHz coming off the floppy and out the serial port, but it'll be 16MHz for any other thing going on (compression/decompression, screen updates, ...). BITD, folks used AppleWorks to get real work done on an Apple II. It drove tons of sales of memory expansion cards and accelerators because it gave you more room to do your work and made that work go faster. Plus, the dial is so cool.
  5. As I mentioned earlier, it's a hard drive surrogate, and it assumes you're using ProDOS - which few games do. Hard drives and floppies each had a very different role on the Apple II, and that's reflected in the floppy-only operating system (DOS, typically version 3.3) vs. the more universal ProDOS that can operate both floppies and hard drives. Your problem is that a lot of software that is on floppy images (most software, if you're counting only games) is on DOS 3.3 images, which simply doesn't play well with hard drives. It wasn't designed for that as a target, and it is painful trying to move from one environment to the other (DOS<->ProDOS). One option for bridging DOS floppy images and ProDOS is the late Glen Bredon's DOS.MASTER program, which allows virtualization of a set of different floppy images to exist on a single ProDOS filesystem, accessing each as a separate volume. It works, but it requires you to keep a good mental map of what's stashed in this jukebox of virtual disks and how to access them. Recently, a lot of effort has been going into lifting games off of floppy images and making them single-loadable, even via ProDOS. If you go to Asimov and look for any title with the text "PRODOS (san inc crack)" in it, those are ProDOS floppy images that would allow you to copy the executable game to your CF card via CiderPress and skip the floppy altogether. So those would be great options for your ProDOS setup. Lastly, your CF card can store .dsk images that you can reconstitute to physical floppies if you like - you could use a program like DiskMaker 8 to go from .dsk on your CF to physical floppy without having to go through ADTPro to transfer.
  6. No, that's not really what the Microdrive is for. It is like a big hard drive for the Apple IIe, and not well suited for individual floppy disk reconstitution. The CFFA3000 is the thing that behaves both like a hard drive and also a virtual floppy drive. Alternatively, there are other virtual drive devies available now. But what you're asking really isn't the Microdrive's primary use case.
  7. The fact that the disk won't boot in the internal That's unfortunate. You need to try with a different disk, maybe even creating your own boot disk with ADTPro. It's either a problem with your internal drive or the media you bought... given the computer is a complete unknown, maybe I put a little more likelihood on the drive being the culprit.
  8. No idea. With Windows that old, you might try plain old ADT (not ADTPro). See ADT 2007_2: https://sourceforge.net/projects/adtpro/files/dos-adt/ADT%202007_2/
  9. Definitely pick a CFFA3000 up when you can, but don't sell the Floppy EMU - you can never have too many gadgets. The reason why the CFFA3000 is so flexible is that it's sitting directly on the bus - and it can insert its phantom Disk II-ness anywhere else in the bus you want it to. Then, any other disk images you want are on the SmartPort, including hard drive or any size floppy images, 5-1/4" included. It can hook itself into DOS 3.3 and speed up Disk II access even more. I try to have one of everything (I "need" to test them for ADTPro compatibility, I tell myself) but the CFFA3000 is really the Swiss Army knife of disk surrogates.
  10. Yes, no reason why the CFFA3000 would prevent that.
  11. Exactly. Bummer they saved $0.27 per machine by soldering it in, too.
  12. Yep - you've got some bad RAM. That's what picture #2 is telling you. Time to open it up, pull out the RAM chips, solder in sockets, and replace the RAM.
  13. Have you tried any other video device with this machine, preferably a retro CRT-based one? Some LCDs simply don't like the A2 video signal.
  14. You will want to re-download. The 5-1/4" images are both 140k.
  15. Maybe, for various approximations of "easy" and "reasonable." They don't usually come up for sale on eBay by themselves, but there are plenty of hacks around to wire up your own. There are replacements such as these available: http://www.ebay.com/itm/c-LAPTOP-STYLE-POWER-SUPPLY-BRICK-FOR-APPLE-IIC-75-90-watts-18-00-S-H-/221294478704 You're in luck - a year or two ago, the answer was "no." Now, it's better: http://www.bigmessowires.com/floppy-emu/ http://tulip-house.ddo.jp/DIGITAL/UNISDISK/english.html
  16. Sounds like it might be the head, head/pressure pad interaction, or stepper mechanism, or... something else mechanical. Keep swapping... it's definitely not the Apple II mobo.
  17. -d1 has a long and troubled past... looks like trouble has returned. Some problem reports over time: https://github.com/AppleWin/AppleWin/issues/286 https://github.com/AppleWin/AppleWin/issues/276 https://github.com/AppleWin/AppleWin/issues/108 I just tried 1.25.0.4, and fix 276 seems to have solved it: https://github.com/AppleWin/AppleWin/releases/tag/v1.25.0.4
  18. Nope, CiderPress is reporting the bytes it sees on the image. AppleCommander reports the same thing. Whomever wrote that file put those bytes in the file length portion of the filesystem structure. It's unlikely ProDOS would have done that on its own, so somebody/something changed the bytes after PD created the file. (It's reported as a Tree, by the way.)
  19. If it beeps when turning on, lots and lots of stuff is working correctly. CPU, RAM, ROM. What might be left is the video circuitry, or your monitor... though you are convinced your monitor is OK. So it might be the video portion of your mobo that is worth a closer look.
  20. Hmm, I'm not sure what I'd call into blame here - the image does seem to be corrupted, as that filesize is nonsensical. Should we throw up our arms in defeat? Should we cry and wail in the streets? Is there no hope for humanity?
  21. Yes, the blown chip would wipe track 0 and nothing would happen at boot. Do you have any other bootable disks that you didn't run through the suspect drive/chip? Ok, that's bad. If you have DOS 3.3 loaded and INIT HELLO produces an I/O error, you've still got a physical problem somewhere. You're not using HD media by chance, are you? How about connecting a drive on the second connector and doing INIT HELLO, D2 ? It could be anything, really... are you absolutely sure the ribbon cable was placed on the header correctly?
  22. http://apple2.org.za/gswv/a2zine/faqs/Csa2FDRIVE.html#012 Electronics houses such as mouser.com and so on will stock it.
  23. It is easy to be off-by-one with the ribbon cable if you have the old, keyless 20-pin header version of the Disk II interface card, which does in fact fry a chip on the analog controller board of the drive. Symptoms are exactly as you describe. Definitely stop inserting disks, as this fried chip makes the drive erase track 0 on any disk it encounters. Can you bootstrap an operating system via audio or serial with ADTPro and do some disk formatting tests? No, that is expected. The controller can be in any slot; it's just that the typical slot used/recommended is #6.
  24. As you can imagine, I have quite a collection of ultra-cheap USB-RS232 adapters. I've been sampling them for years, and they're basically just getting worse. And then from time to time the legitimate chipset houses clamp down on the cloners and make their drivers incompatible (and sometimes brick the adapter, like FTDI has done once or twice). I've not found it worthwhile to race to the bottom in this space.
  25. And importantly - the chain must terminate with the 5-1/4".
