  1. I'm glad you figured it out (without any help from me). I saw your earlier post, and started thinking about it, and was going to verify that you had high speed version of the 4066 (74HCT4066), instead of the much slower CD4066. But then the weekend with the wife kinda put a damper on that. And if it hadn't been that, the resistor networks were my next suspect.
  2. Just need a WiFi micro-SD card, and you'll never have to open the case. Do they make such a thing?
  3. You can probably pick up some pointers from the recent 3D printed case design for the eclaireXL.
  4. There were some mistakes on the ARROW2JOY Bill of Materials shown on my website. I discovered this when making a test order utilizing the embedded part number links. Below is the corrected BOM for items 4 and 5. This is only a photo capture from the ARROW2JOY page, so these links will not be functional. For the time being I chose alternative vendors for these corrected items, since I have direct experience ordering these particular items from them and I know that they will work. Later if I find suitable Digi-Key alternatives I'll update the BOM based on that. If someone has already ordered from the previous BOM, please send me a PM and your address, and I'll be sure you get the right parts to complete your assembly.
  5. You are witnessing the evolution of things, with the later XLD docs having more details then the XEL in some regards. However I usually try to show plugs that will need to be soldered from that viewpoint. So if you did it with a reversed viewpoint, that would explain why there were issues. Presently there is no way to change the acceleration speed of the mouse. In fact the mouse firmware is still what I consider to be beta. It is my intention to someday revisit that and add the means to alter parameters such as resolution and speed.
  6. I always use this as my guide. Made by Bryan, the creator of the UAV.
  7. Very interesting . Can't say I understand why there was an issue, but I'm glad you got it working. For others to reference, here's some diagrams. Both views of the DIN-13 jack are assuming you are looking at it from the solder-side on the plug. Its also important that the VBXE's connections match up when connecting to the 10 pin header. 1088XEL (RGB Connections ONLY) 1088XLD (RGB & Standard Video Connections) RGB Header (XEL)
  8. If that were true, then none of my ST monitors would work... but they do . There is one thing that is different then it should have been, and that is the left and right audio output order, which was inadvertently reversed from what I wanted it to be. Not really a big deal, except when feeding an ST monitor it really requires that the 1088XEL (and XLD which is the same setup) be set to mono, otherwise you'll be missing all but the GTIA produced audio signal.
  9. Yes I see your point. But sometimes adding in all the possibilities that maybe only a few would use, just creates a bigger board, more cost, and can endanger the project as a result. That is why I asked how many of those ABBUC MIDI board owners were actually using the MIDI-THRU. Any idea?
  10. I was merely talking about the possibilities of how one could approach this from a bare bones perspective, not promoting that this should actually be done in reality. Although for the record, I don't care what people end up doing with their 1088XEL. Sometimes it's just fun to ponder and discuss other approaches. Life would get boring otherwise . The XEL-CF concept did originate from the original MyIDE circuit. Anyone can look back at the beginnings of that topic and see that this was true. Over time the circuit that was eventually to become the XEL-CF3 had evolved beyond that, and through incorporation of my ideas combined with design ideas by other people, Bob Woolley being a big influence, it became much more then it's roots.
  11. I stand corrected on how many ABBUC based MIDI interfaces are in the wild . And out of all those people, how many actively use the MIDI-THRU jack? Because that's really what matters the most to this discussion, not whether something has a certain feature, but whether enough people use it to justify its inclusion into a future product.
  12. Yes this is quite possible to do, and in it's simplest form it could simply be an alternative plug-in board for the U1MB. I'm guessing if at least 5 boards were built, which seems to be the minimum for many of the PCB manufacturers, that the parts cost per board would likely come in around $15-20 for all of the required components and even less so if you already have a donor MMU, Basic and OS ROM. I did kick around this idea over a year ago, but never pursued it. If you don't want to use SDX, but still wanted to utilize the XEL-CF3 add-on board, I suppose you could use a patched version of the MyIDE OS and point it to the correct IDE register locations.
  13. Announcement Thanks to Dropcheck, there is now a complete BOM for the standard 1088XLD board set posted at my website in the 1088XLD page. She initially put this together back when the project was still in its beta phase, and refined it to arrive at the version now being posted. I also uploaded the FPD (Front Panel Designer) file for the standard front panel as well, which allows a panel to be made at Front Panel Express after downloading their designer application (runs on: Windows, MAC OS, and Linux). Using the FPD application, you can modify the text and graphics you wish to be displayed, as well as the material and color. Please keep in mind that there are strict limits as to how far any graphics can spill over into the surrounding space due to the 1050 drive bezel's inside cut-out. So it's best to print it out at 1:1 scale to verify with the bezel in place. A bare board set is available from: The Brewing Academy at a very reasonable price, as well as a completely built systems.

  14. Hardware MIDI-Thru: maybe ask for a show of hands as to who is presently using this (hint: take a poll). However I doubt its very much in use based on what's been available software-wise in the A8 scene. Keep in mind that none of the commercial interfaces BITD ever supported it and/or included it. And although there was one ABBUC offering many years ago that had it, you won't find a lot of those in the wild. Of course some of my recent projects, as well as ivop's had it, although personally I rarely used it other than running a few quick tests to see if it worked. And finally its not an end all if you don't include it, since there are ways to do it via other methods. Sometimes you've got to go with your gut and ignore a good portion of the feature requests. If I didn't do this, there never would have been a 1088XEL or 1088XLD. And I've seen numerous projects bite the dust when the developer tried to please everyone.
