  1. I dug out my PS3000 for the purposes of providing enough info so that someone else could get a double-sided floppy drive working in a PS3000. I no longer have my Atari computer setup as I do not use this equipment anymore. Maybe when I have time to setup my Atari computer, I will try to provide a video.
  2. Almost forgot about the Head Select and the Device Select pins. -I cannot recall whether the "Head Select" pin was used for the original single-sided floppy in the PS3000. It definitely has to be wired for a double-sided drive. -I was using this PS3000 with a Mega ST, so I had to wire the 34 pin connector so that the floppy drive in the monitor was "Drive Select 1" instead of "Drive Select 0". If I did not do this then both the PS3000 drive and the internal drive in the Mega ST would both respond as drive A. The PS3000 comes up as drive B when it is wired to "Drive Select 1". If you have an original 520ST with no built-in drive then wire the PS3000 drive to be on "Drive Select 0". That is unless you plan to run with two drives on the 520ST. If you plan to run two drives then wire the PS3000 drive to be "Drive Select 1".
  3. The PS3000 monitor was made by JVC. JVC also produced an SC1224 monitor. I found that the PS3000 monitor and the JVC SC1224 have better picture quality than the Goldstar or Samsung SC1224 monitors. I have both a PS3000 and a JVC SC1224.
  4. It is not a big deal to open a PS3000 monitor. There are only 7 screws holding the back housing on. -Two of them are on the top of the monitor and are hidden by plastic covers. The plastic covers have pry holes and pop off pretty easily. -The next two screws are on either side of the part that houses the floppy drive. If you spin the monitor around so the back housing is facing you, look at the power switch. You will see the first screw. The second one is on the other side in the exact same location. -There is one screw in the hatch that houses the brightness, contrast and volume dials. Don't forget to remove all three dials as well, or the back housing will catch on them. The dials can be removed with your fingernails. -The last set of screws are easily located underneath the monitor. (The screws that hold the stand to the monitor do not need to be removed.) Once you have all 7 screws and the dials removed, the back housing should slide off without binding on anything.
  5. Here's some pictures of the PS3000 that I modded so that I could install a double-sided floppy drive. I did not have to modify the power connector. It fit the double-sided drive without any modification. The data connector was the only part that needed to be modified. For the data connector, I had to remove the original mylar connector on the board and solder in a 34 pin ribbon cable with the appropriate connector attached. I figured out the wiring for the 34 pin connector by comparing the external drive connector with the pads on the board. I also had to remove the bottom shielding of the double-sided drive so that it would fit in the monitor. The two mounting screw holes for the single-sided drive are in the same location as the double-sided drive. I used the original screws for the single-sided drive to bolt in the double-sided drive. I hope this helps. Let me know if you have any further questions.

  7. I haven't forgotten about this discussion. It's been a very busy year for me. I'll try and get some pics for you in the next few days.
  8. There's no secret. The XC-1411 monitor came from Atari's main office in Markham, Ontario, Canada. As far as I'm aware they used it in their service department to diagnose and repair the 8-bit series of computers. When Atari closed their doors in Markham, Ontario it was left behind. It was given to me by a friend. (I think I may have actually traded a surround sound module, that I built in a high school electronics class, for the XC-1411.) I am not exactly sure how he wound up with this monitor. I used it as a TV for several years. After that, it sat in my parent's basement for well over 20 years. I finally dug it out two years ago and had another friend look at it because it had developed a peculiar issue with colour fade out. Essentially after about 20 minutes the picture would fade to black and white. He determined that a capacitor had gone bad and replaced it. As a precaution, he also went further and replaced all of the electrolytic capacitors. From what I know he then put it on Ebay for sale. If the XC-1411 is the one that I let go, I hope the new owner can get it repaired. It would be a shame to see it go to waste. The XC-1411 was manufactured by Goldstar (LG Electronics). Goldstar was also one of 3 companies that manufactured the SC1224 monitor for the Atari ST series of computers. The XC-1411 closely resembles the Goldstar SC1224 monitor. One of the differences is that the XC-1411 monitor has a red power indicator whereas the SC1224 has a green power indicator. Electronically speaking the XC-1411 may be a similar design to the Goldstar SC1224 with only one major difference. The XC-1411 would have an additional composite video to RGB circuit.
  9. Someone sold one of those monitors for me recently. Considering this is a rare monitor I'm willing to be this is probably the one that I let go. Did you purchase this monitor from someone in Canada? If so, I can provide a little information about its history.
  10. As I recall it wasn't that difficult. The floppy drive that is required is the original big button drive from a SF314. I don't recall having to change the power connector. I did have to remove the data connector and solder in a 34 pin ribbon cable for a standard floppy drive. I still have one of the PS3000 monitors that I modded. I will try to take some pics and post them.
  11. There were 3 SC1224 monitor manufacturers. If I recall correctly, JVC manufactured the PS3000 and the first SC1224. Samsung and Goldstar manufactured the other two versions of the SC1224. The XC1411 was definitely made by Goldstar.
  12. I know this is an old topic, however just thought I would add my 2 cents. I actually installed 720k disk drives in two PS3000 monitors. It wasn't difficult at all. It was also easy to set them up so that the drive would be detected as B: instead of A: so it could be used with ST computers that had a built-in disk drive.
