    BlueSCSI v1.0-c external LED?

    Awesome, thanks! (didn't realise "P" just stood for "pin") :oops:

    BlueSCSI v1.0-c external LED?

    OK, so if I attach the LED to the 5v & GND circled in the photo that's just for power, right? It says "you can use the same pin, PA0 as 1.1 does, you will have to solder it yourself" but I don't see a PA0. and it says I'll need a resistor rated for my LED (between 300-500 ohms. I know very...

    BlueSCSI v1.0-c external LED?

    That's what I was looking for, thanks. Don't know a lot about the hardware part of it but I'll see if I can make sense of it.

    BlueSCSI v1.0-c external LED?

    Can I attach an external LED to my BlueSCSI v1.0-c? If so, which 2 posts do I attach it to?

    That looks like the part, thanks!

    Yet another BlueSCSI SE/30 bracket post…

    I have an SE/30 that had been converted from an SE. I'm assuming the chassis was upgraded as well to accomodate a PDS card. Unfortunately, the part of the chassis that allows for a bracket to be attached aligning with the windowed opening on the back of the Mac is not there. I can't take the one...

    Battery accessory for external wafer battery holder

    I bought a few of the excellent external battery holders from @Ron's Computer Videos at VCF East a few weeks ago. After recapping my SE/30's analog board I decided to try one out. Because I prefer to keep vintage gear original and intact, I made a proxy battery that fits the stock battery holder...

    non-aluminum axial caps polarity

    Thanks @JDW! I have seen your video but I didn't remember that part. It appears the Reddit poster was correct, although I do trust your guidance more :)

    non-aluminum axial caps polarity

    Recapping my SE with a cap list from @JDW. They sent me 2 axial caps for C11 aand C18 that I've never seen before. I think it's a "Vishay" cap. I'm not sure which side is neg- or pos+. I googled it and got only one hit from reddit . I don't really trust Reddit advice much though so asking...

    Macintosh SE or SE/30 Fan Bracket

    I know this is an old thread but for those of you who are sans 3D printer, where do you get your 3D prints made? I tried PCBway for the fan bracket on Post#1 of this thread but the shipping is stupid expensive for an $8 part to New Jersey. there's no chance I'm clicking the "Place Order" button...

    No Wonder my SE screen just has a vertical line

    yea, looks like your boards are pretty different than mine as your fans get power direct from the PSU plug.

    No Wonder my SE screen just has a vertical line

    Thanks. Are your fans wired? That's probably why those things are missing since you don't need power to the fan terminal ports.

    No Wonder my SE screen just has a vertical line

    OK, here's what I think I need to do. Find out what that transistor is at R31 and replace it, then run a bodge wire at W6. That should provide power to the 2 terminal holes for the fan. One thing I find odd is that the wire at W6 isn't protected and it easily comes in contact with the PSU...

    No Wonder my SE screen just has a vertical line

    Thanks but this SE has a squirrel cage fan. The SE/30 I'm transferring to is an SE conversion to an SE/30 and also has a squirrel cage fan. If there's a new replacement for a squirrel cage that would be great. I think it was mentioned that a regular blade fan may hit the CRT yoke, plus I think...
