  1. Thanks Darrell! I received the cable assemblies and looks like I have the version with both headers being straight, not half as right-angle. I'll have to check clearances but maybe I can gently bend the pins to fix that. Otherwise I'm shelving the build for now as there seems to be part shortages and I have to wait.
  2. Excellent this was a solution I was looking for too for my build :)
  3. Cool! Thanks guys for the hints and various pointers. I';ll have a look around for the original SIDs, just need to be patient. In the meantime lot's of reading up if I am going to build this.
  4. Hi all So like some other folks around here, it's the MB6582 bug that has now got me. But before I commit, I wondered about the status of obtaining the right SID clones vs tracking down the old ones. I've seen various older postings about the clones and some comments to the sound quality. These days, which SID clone would be best used today in a MB6582? Or is simply sticking to the original SID still the way to go, despite their age (and maybe fake ones floating around)? Thanks for any guidance.
  5. OK that brings me to another question about the MB6582, separate post....
  6. +1 Good to know, wondering if this was ever tested as it looks fun to build.
  7. +1 Looking to get a couple of modules too, but hope those guys are OK and only on holiday . The brd files for the newer stuff aren't available but at least the older ones are if it comes to that.

    Building an MB808 clone the long, hard way. Link to old thread.

    The power supply, likely faulty.

    Here's the work bench with Christian Hartig's TR-8060 being built and fitted into the case.
  14. Should have updated this....an air-driven reflow station is your friend when it comes to making fixes to SMD parts! This was a lot of fun to do and get working. Looking forward to building another one day.
  15. Well, from bad to worse, looks like my board is shorted now. Not sure how that happened but I measure 2.5 ohms resistance between ground and 5V. That was a waste. :-/
  16. Hi Those rows are all off. I'll re-flow the solder at those locations to see if there's any life. So close!
  17. HI all, looks like I'm almost there. From what I have seen in the power-on test, I have 3 rows not working. I'm guessing this is down to a cold solder joint or a short. They are (going by transistor Q number): Q29, Q19 and Q22. Would a cold solder joint some place be the top of the list of culprits?
  18. Wow, what an awesome build this all was. Now that the 'hard' part is done, comes with 'soft' part: What's not clear to me, using a virgin PIC (F4620), is what firmware this BLM would use? Is it just a matter of loading the bootloader and that's it? Or should the blm_scalar_v1.0a.zip file from the MIOS download site?
  19. Very nice case, just got mine, plus the Mouser order and acrylic surface, this will be a good project to pass the winter months. :-)
  20. I'm in as well, looks like on a waiting list possibly, but definitely quantity of 1 each.
  21. This would be great for the second bare board I have. Any plans for a group build/buy?
  22. Just to let everyone know I am still progressing :) The hardest and most time consuming part (besides work and life in general) has been machining the panel. In other news, I have plenty of photos of the build, but not yet found a way to upload to the gallery; the power supply circuit seems not to work, it might be a bad lot of parts, so I need to create a different power supply for the main board; I see that Christian Hartig has taken the site down as he's no longer working on the project. I that makes it one of the last TR-808 clone builds left. Hopefully it's not because it turns u
  23. Hi guys SO here is the long and the short of it: I spent many hours reading through everything last summer, again picking up things this summer. I noted that there was Moogah's cool version since taken over by Doug Wellington (https://www.eight-oh-eitght.org/, now defunct). Thanks to a posting above, I found the Eagle PCB masks for each section of the project, but no knowledge on how to merge all the masks/layers together, so I didn't spend much time on it. I also had to think about what I read of the old 808 forum through the Internet Archive, which had some postings above board er
  24. Hi everyone I want to thank you all for your input last year. I finally got this project started, and am part way. It's taken a long time to get materials and do the research, but looks like it is progressing well. I'll post to a separate thread for those who are interested.
