  1. Thanks, for the reply. If you look in the picture, the drive is a TEAC FD-235HF according to TEAC's documentation this is an HD drive. It does have the density switch installed. I'm starting to believe it's an issue with Windows 10. I haven't really had a chance to try this setup in an older PC with Win XP or earlier, of course those older PCs tend to have floppy disk drive controllers so I wouldn't have to try this workaround. The LS-120 route might be worth pursuing if it can be made to work in Win 10. The only problem with that option is my company will not allow purchases from ebay.
  2. I found an Ohio Scientific disk drive with a Model of C1PMF in my garage that I forgot I even had. I can't seem to find anything about it on the internet. I don't believe the I have the C1P computer itself, (I think I would have remembered that.) so I have no way to test if it is still functional. I did clean it up and I opened it up to see what is inside. It has just the floppy disk drive and a power supply. I tested the power supply and found that the 5V and 12V are still good. I thought for sure the drive would have a bad drive belt but it seems to have a direct drive motor. It is a double sided 5 1/4 inch, half height drive. I was able to find some information on the drive itself, which is a Mitsubishi M4853. It's a little unusual as it is double sided, double density, but it has 80 tracks. There are only 16 sectors per track so total formatted capacity is 640K. Does anybody know if these were standard drives for the Challenger C1P?
  3. I'm excited that I'm finally getting close to getting my Phoenix. I was one of the backers on Kickstarter last year, and when you fell back to plan B, I was one of the first people to put in my order on the Collectorvision web site. I believe that the Phoenix is truly a labor of love. I'm happy to see that you guys have the intestinal fortitude to complete this project despite the risks. We're talking a very niche market here, but you had a dream and you were able to pull it off. My hat is off to you! I think it's great that you are basing the Phoenix on existing open source cores, and that it remains an open source platform. The ZX Spectrum, MSX, and other Z80 cores should be relatively easy to port because of this. With the expansion module port, the Phoenix has the potential to support I/O and cartridge slots for most of the 8-bit platforms, though there doesn't seem to be enough pins for direct connection to most carts. There are ways around this at higher data transfer rates, but it's going to increase the complexity of your cartridge adapter. Anyway I'm sure this has already previously been discussed in great detail. Still the possibilities are exciting, and I'm glad see it come to fruition. I hope to see you guys at PRGE next week.
  4. Another curious thing is that with a 720K disk installed, if I try to format the disk in Windows 10, the only option that Windows will give me for media size is 640K. If I attempt to format the disk at this point, the formatting fails. However if I install a 720K formatted disk I can read and write to it no problem. On further research on the FC-1 SCSI floppy interface that comes with this drive, it looks like it could actually control up to three floppy disk drives. It should be able to work with 720K, 1.44M, or 2.88M. Normal density, high density, or enhanced density. Perhaps the problem is the SCSI cards I have tried? I have tried the Adaptec 2940UW and the Adaptec 29160. Neither of these officially support Windows 10 although I've been able to make them work.
  5. I work with a lot of legacy computers. This is an Avionics shop environment, so we can't just upgrade to modern hardware as we have to use whatever was specified at the time of design. Consequently, this means that it is often necessary for me to transfer data to modern computers via 3.5" floppy disk. (Some of our equipment still had 5.25" inch floppies.) As modern PC's don't have floppy disk controllers, we have purchased external USB floppies. These work most of the time, but the floppy drive mechanisms are inferior to legacy drives and they are slow and error prone. Because of this I have been trying to find a more robust solution to work with my modern PC running Windows 10. We have access to new old stock of of TEAC FD-235HS -711 SCSI Floppy disk drives, these consist of a FD-235HF-3700 floppy drive mechanism with a TEAC FC-1 SCSI floppy disk controller bolted on. I was able to install this drive into my PC and I can access it with and Adaptec SCSI card. However, I have been unable to get the drive to recognize HD floppy disks. It won't read or write in HD format. If I format them on an older machine as 720K normal density, then the drive has no problem reading and writing to the disk. I do not have documentation for these drives. I have been able to find some documentation for the FC-1 which also discusses the floppy disk jumpers, however, it is for a different floppy drive mechanism with a different layout. Since I know there are a lot of smart people who frequent these forums, I thought I would post this here. I've attached a picture of the jumper settings as they are set now. They are all factory default except the SCSI ID has been set to 2. If anybody has any idea what may be going on here, please let me know. From what I've been able to find, this should work, but I've tried two brand new drives and I have the same issue with both. Thanks.
  6. I didn't know you were giving them out last year, but since I'll be there again this year. Barry Reeves Mutterminder Tacoma, WA USA See you there!
  7. Packaging last year was fantastic. But Zombie Road Kill by Jason Santuci of Gemintronic, packaging by D. C. Stuelpner. Went above and beyond.
  8. Mappy is definitely an amazing technical achievement. Mappy by John Champeau: Player and Enemy anti-flicker code
  9. If you are going to include Edtris in your rarity guide. You should also have SoundX. I got the game at the same time as I got Edtris, from Ed Federmeyer in 1995.
  10. I'm trying to find some of this information myself. I haven't had much luck finding any information on the internet. The most information I could find was right here on the Atari Age forums. However, if schematics or pin-outs exist for this system I haven't been able to find them. From what I have been able to find, there are at least two different hardware configurations for NTSC systems. One takes 3 voltages and may not have come with a power supply. (If so, this is very peculiar, as this isn't exactly an commonly available power supply.) Apparently, an original Colecovision supply will work with these, although the power supply is a common failure point of the Colecovision, so I'm not sure this does much to ameliorate the problem of a missing power supply. The second type of Dina, which is the type I have, takes a single 5V supply, which in my case, came with the unit. Since the Sega Genesis controller is said to work with the unit, it seems likely that there is +5vdc on pin 5. When I have a chance, I'll check mine, but it sure would be nice if there were a place where all of the available information on the console could be collect into one place. Maybe there already is, and there just isn't much information.
  11. My goodness! What a big surprise. I don't think you'll have any trouble selling all those copies. I wouldn't mind have a couple of those ProNES GamePad Adapters either. And the Atari Y/C ProVideo Board...
  12. I sent a PM to order a multicart plus 2 extension carts.
  13. I've already put in my pre-order. Essentially I just carried over my kick starter reward. I think this system is very promising. With the expansion port, it should be possible to add on fairly inexpensive cartridge adapters for each of the supported systems. Since I'd like to see the 7800 supported next. How about making the first cartridge adapter 7800 compatible. That way, people could use it for their 2600 carts, while you are working on 7800 support. Just an idea...
  14. I'm not sure they sold assembled units. You would have had to build it yourself. I did buy the LNW Expansion interface, but it was just a bare PCB with a parts list. The advantage over the Radio Shack expansion interface, was that you could build it one section at a time. In this way I was able to add memory, a printer interface, a serial port, and a floppy disk controller as I could afford it. I found a fiberglass case for it from a third party.
  15. Since my first computer was the TRS-80 Model I, ever since I saw them in 80-Micro Magazine, I always wanted an LNW-80. TRS-80 compatible computer with color graphics. I've never even seen one though...
