Hello Phipli,Your reply is about a different product.
My reply was mostly in reference to your comment:
"More frustratingly, at the time, and still to some degree, this forum ends up providing a large amount of support to BlueSCSIs that they themselves have sold. Search for "blueSCSI not working" or "BlueSCSI help" or whatever and count the results. Even now there are about three or more threads every week providing support for their devices, which is tedious and frustrating, especially as it isn't easy to troubleshoot and wastes our time."
I don't think that helping any member, no matter if its a BlueSCSI a ZuluSCSI a GreenSCSI or a YellowSCSI (LMAO Dr Seuss style) should be thought of as a waste of time. My main point is that we are all in this together and most of us, myself included, are learning new things daily from great minds like yourself. My wife says collecting these computers are a waste of time too, but well, here we are.
You once graciously helped my with a SuperMac Nubus Video card, that after much reading into, I found out was not of the best quality (made in China) vs its competitors. Does that mean I should not have gotten your amazing support vs a person with say a radius card? I don't think so but that is just my opinion. I think we all deserve help when coming to public forums, its part of the experience.
Again Phipli, I "Phlippling" (flipping; see what I did there!) love you buddy just didn't like the waste of time comment. I don't think anyone should be considered a waste of time, well to some degree lol...
Cheesestraws,
I will second what Bnys said a few posts back:
"I'm sorry this was a sensitive subject but I had no idea there were any difficulties with this project or its creators. I hope you're able to heal from any abuse you had to put up with. Genuinely, thank you for your input."
Members like you keep this place alive! I hate hearing when you guys get put down especially since it is you guys that we come to for support and suggestions.
Thanks guys for the continued support as always!
As do I. Which is why I spend an absolutely huge amount of time assisting people on this forum.
On the other hand, I think that if you are profiting by selling a product, you have a responsibility to provide support.
I also think that before asking for help, you should read the instructions, regardless of...
it being easier.
... but many people don't.
These are retro products, not stuff made by someone who is still selling them and has manuals and a support email address / discord / ticket system.
Repeatedly being asked the same question every week grinds you down. This is a fact, I'm not saying this because I'm being bitter about people starting out. Its nice to imagine a forum as a wonderful place to come for technical support, but it is important to search for old threads first, because... well, eventually people stop replying. People just get worn out. Especially on topics that are well documented.
You're talking like I don't actually still try to help people, I do, but it is impossible not to be frustrated answering the same question again and again. The way you talk about the forum makes it sound like a paid for service with its intention being to provide support. Its more like a club for people with a similar interest, and if I was spending every meetup of a club doing hard graft for other people... sooner or later I'd stop going. Truth be told - I've come close here and would have previously walked away if it wasn't for my good friends and the fun, jolly interactions with strangers.

I meant absolutely zero disrespect and I am sorry if I came off as such. You are a great person and I have never thought differently of you. I definitely never said you don't actively help people and I am sorry if I came off as thinking so, that was never my intention nor is than even remotely true about you. Your service on this forum speaks for itself and I mean that in the most spectacular way.
Sincerely, I will leave this hear as to not cause any more trouble than I may have caused.
My sincere apologies Phipli!
Update for anyone who cares: I gave the logic board a thorough cleaning, and replaced the PSU with the suggested Mean Well model. I wasn't sure if it would do anything at this stage, but I got fan spin and a chime!
Next up is getting some help with a recap, ordering upgrades (probably from SiliconInsider; 512 meg VRAM and 8 meg RAM, SCSI replacement) and figuring out how to cheaply get a small LCD for the machine. Any suggestions for the best OS version to install? Does low-latency matter when it comes to VRAM?

All apple VRAM is fast enough for the LC II, so you should be fine with anything. The speed is dictated by the computer, so there is no benefit putting faster stuff in. I think 100ns or faster is fine for these?
I'd probably set it up to dual boot 7.1 and 7.5.3
if I was going for only one, I'd likely go with 7.1 for the smaller memory footprint. There are benefits to both.Excellent news
congratulations!Hey another update: I was able to locally get a small VGA LCD and a couple of adapters (one is the unimac 82d-style), so why not fire it up again and see what happens? Unfortunately, I have lines on the screen no matter what dip switch settings I use, and in monochrome or color modes. I’ve heard this can be bad VRAM but maybe the recap will solve this as well? I have a 512k VRAM SIMM coming at some point. Cleaning and reseating the VRAM did not help things at all. 
Every 16th pixel is affected. Seems like one of the data lines is broken? There's 40 affected bits across the width of the screen which means you're running at 640 pixels width. It appears to be the third bit (counting from the right most bit). Bits 0-1,3-15 are ok but bit 2 is bad.
But you said you see the same thing in color mode? If it's the same spacing it's probably not the VRAM data lines.
But you said you see the same thing in color mode? If it's the same spacing it's probably not the VRAM data lines.
Would this indicate a VRAM issue after all? In Color mode the bars can vary a bit more (and somewhat disappear depending on what’s on screen), but I chalked that up to the way the system is dithering to make the different colors.
LC needs a VRAM upgrade to do 256 on a 640x480. Sadly, the upgrade makes its slow video even slower
Definitely looks like a VRAM problem since the spacing between bars depends on the color depth.
In 1 bit color mode (Black & White), the bars occur every 16 pixels (16 bits).
In 4 bit color mode (16 colors), the bars occur every 4 pixels (16 bits).
In 2 bit color mode (4 colors), I would expect the bars to occur every 8 pixels (16 bits).
In 8 bit color mode (256 colors), I would expect the bars to occur every 2 pixels (16 bits).
Does the LC have a 16 bit data bus? You need to fix the 3rd data bit.
To the RAM and I guess VRAM yes. It's 32bit to the ROM and PDS if I remember, but that isn't applicable here
shouldn't be, just make sure it's a good quality wirewrap wire, like kynar or something
