  1. Prototypes arrived early! Unfortunately mouser order is still in transit so will just have to look at them till the parts arrive. Note I added a pin out to the upper right for hooking up a programmer (so I dont have to solder legs on and risk shorts anymore while debugging Will design/print an internal mount now that I have some holes to mount to this weekend.
  2. Nice! I know a few others who have recently built one too. Any notes or photos you have I'd love to hear. Where did you get your PCB from? How are you handling termination (I suppose you are just terminating the next device since you made a chain). Anything you think that could be improved on the hardware or software side? I'm on the lookout too for a SCSI PowerBook to build a model for that. Also may order a few of the break out boards like RaSCSI has if people would like to mount externally.
  3. That is for his V1 - which I accidentally translated first I have a lot of cleanup to do in the repo, but the V2 is the software I'm running on my prototypes. Will cleanup and push what I have later this week before the new prototypes arrive (assembly finished btw, shipping soon!)
  4. ztto - the commit history/fork/etc is all there in github. There is only 78 ifs in the entire code, most are macros - are you looking at ArdSCSinoV2.ino ? I do plan to review more of those functions to see if there's opportunity to optimize - haven't done c++ in quite a while, but open to any suggestions!
  5. When I opened my keyboard & mouse a month or so ago I honestly wondered if JDW would make a JDW in depth video of recapping a keyboard and mouse
  6. Placed the order of 5 for the latest rev prototypes (with passive term) this morning. Should be a week and a half till they get here and I can put them through their paces.
  7. Good point! I don't have any active terminators so hadn't consider that. By limiting to just this one device - you're just saying in documentation? There is no way in software or hardware to prevent this I wouldn't think? Passive termination is needed even if it's the only device on the chain I've found for the ztto version (have been using a unpowered drive at the end of the chain or the RaSCSI to do this while testing.) Thanks for the feedback, that's why I put it out here now!
  8. Thats honestly why I go visit him a few times a year Though not lately... At 72mm x 44mm I'd think it would - though I don't have any PowerBook to test it on (though I should get one...) Just a matter of wiring up the pin out to that connector.
  9. Appreciate that - though I'd like to take a stab at learning more myself after I get the initial designs done for termination and do some software updates. If you'd be willing, once I get there, to bounce the designs off you and get feedback, that'd be great!
  10. Thanks for that feedback - and you're right - it's mostly for me to learn more about PCB design and to say I could
  11. gotta make due with whats around - needed something to hold it up while testing Also hello from South of St. Cloud! Could hand deliver you one next time I drive to my buddies house in Norwood/Young America
  12. That was my top contender too - I'm getting the next round in blue to see how close it matches the blue pill. Termination should be enabled or disabled via two jumpers (and maybe the same switch as RaSCSI if it all works out.) Edit: I looked at these inline scsi terminators too - but they're a bit expensive and discontinued - though you can find a few similar on ebay. https://www.monoprice.com/product?c_id=&cp_id=&cs_id=&p_id=806&sep=1&format=2
  13. Hi all, I’ve been working on building the ArdSCSino-stm32 https://github.com/ztto/ArdSCSino-stm32 (original) https://github.com/erichelgeson/ArdSCSino-stm32 (my fork) to see if it’s a suitable replacement for SCSI Hard Drives in our vintage Macs. I’ve mentioned it in passing a few times on the forums but now I’ve made some progress I wanted to share! There is still a lot left to do, but I'm to a point where I'm looking for feedback! This is my first hardware project - I find it amazing that you can create a PCB in KiCad and have it printed and shipped in a
  14. Yes you feel it seat. Don't have to push hard just firm till you feel it.
  15. Sometimes seeing it in action answers a lot of questions. Hopefully this helps: PXL_20201006_014540864.mp4
  16. Mac I believe? Apple color hi resolution RGB display - not sure - I didnt have a IIgs or Mac in that time period. It does work on connected to an LCIII though - thought it was the 12" toppers but it's a bit wider. It's an RJ-11 port though - just plugged it into my MacBook Pro and it identifies as an Apple USB Modem - just seems an odd thing. Must have came with a laptop he got and just through it in the drawer.
  17. Yes, there is a chance. I saw someone replace a tantalum cap backwards a few times and blow it each time - did work after they realized it was backwards.
  18. Well I already tore it apart so heres a few photos
  19. I do! Will take some photos tonight if no one else has.
