  1. I've got the Hong Kong 410 without the handle. I bought a belt replacement kit with 4 belts from console5. I saw a few mentions of people having issues replacing the rewind belt. I couldn't find much on it, but I was able to successfully replace the rewind belt, and it wasn't that difficult, so I figured I'd post instructions and a few pictures to help other out. Disassemble the 410 down to the player internals. Remove the circuit board, but I'd recommend against removing the tape heads. I now need to reset the azimuth, but I guessed and it loads tapes. If you need to remove the play head, just remove the screw on the right, and slide the play head out from the spring/washer/screw on the left. Once you get down to the mechanical portion, the main belt, and the two that drive the counter are fairly easy to switch. The rewind belt is a little more interesting. First, rotate the left spindle, pushing on the top to give a bit of slack. Use a small flatblade screwdriver to pull the belt up. Once the belt is freed from the left spindle, it'll still seem trapped around another pulley under the center of the deck. Now, flip over the mechanical deck. On the left, there is a white plastic nut. Use a flat blade screwdriver to rotate the nut. It should then slide up and off the spindle. With the nut off, you should be able to slide the white arm up and off the peg. At this point, you should be able to free the white arm, which has the smaller hidden spindle. There is a red cap that makes getting the old belt out and the new belt in a little interesting, But, once the new belt is wrapped around this spindle, you should be able to reverse the instructions to re-insert the arm, feeding the belt through to the other side. After the arm is reinstalled, flip the unit over and slide the belt around the left spindle. After I did this, my deck seems to play and rewind perfectly. I didn't realize I shouldn't mess with the azimuth screw, so even though the deck seems to load most tapes fine, I really need to get an azimuth adjustment tape to dial it in. The best advice is to go slow and don't force anything, take pictures as you go if you don't trust your memory.
  2. I've got an Atari 400 with B-Key and 48KB of RAM (by Intec). It seems this was a common mod. But, I noticed this Intec board on the bottom of the main board, an Intec MM0730. Does anyone know what this add-in board does? A Google search for this model number turns up nothing. I've attached a picture of it.
  3. How did you open the case? I have two c017945 that both blew. I was a bit of an idiot plugging the second one in. I have a 400 and I had moved some things around, and when I powered it up, after about 2 or 3 seconds, it blew. I thought that was odd, and thought it must just have been the power supply going bad, so I plugged in the other one, and it blew after 2-3seconds. It was clearly the 400 that had an issue. I took it apart, and I think I know what caused the issue. The RF cable comes out from near the front, all the way to the back, and is wrapped around a ferrite donut. Very close to that, is a little plastic clip, that *was* stuck to the inside of the case. When I opened the case, the clip was not sticky any more. My guess is that when I moved the 400, the ferrite donut must have shorted out a couple pins, which caused the fuse to blow. I've ordered a couple more supplies, but I'm curious that I may want to try replacing the fuse in one of the old ones to see if that works before I plug in the new ones I bought.
  4. Can someone with the b-key pop the space bar off and take a picture of the stabilizer? I've got a 400 with b-key, and I'm missing the plastic bits that connect the stabilizer bar to the ends of the space bar. I tried using the little piece at the ends from a cherry mx board with costar stabilizers, but they were a bit to tall. In a pinch, I think I could get a new set of those and shave down the cross top to make them a lower profile. The pieces are these bits http://www.wasdkeyboards.com/index.php/products/keyboard-parts/cherry-mx-keycap-stabilizer-insert-2pcs.html Sent from my iPhone using Tapatalk
