Hosiden is a very large company. They also have exited the LCD business over two decades ago.

I've now uploaded the reshaped version.

There we go - I'll upload this alongside the old version on github juuust in case. @croissantking may I use your image of the filed-down install to explain the reason for this? I'm not sure it'll fit as my 8100 board exists without a case, and I don't have an 840av at all, but... It should be an...

Almost certainly custom-wound for the job, and if not, most definitely long-obsoleted. Since inverters are typically resonant circuits, replacing with some other random transformer from another inverter might not go well. I'd look into replacing the whole inverter, not necessarily from another...

I've been ridiculously busy lately, but the quickest and easiest way I can help is designing an add-on for existing adapters, as above. Show me what kinda adapter you can buy locally and I'll try to eyeball a termination PCB when I'm free.

So done with wire bodges.

Hmm, I might edit the PCB outline later so no filing is needed.

I could probably draft one out quick when I have some free time - most of the stuff needed already exists in my designs/parts library. What does your 68-50 adapter look like?

That board looks clean in the same sense that I look like Jennifer Aniston, I'm afraid. You have a fair few crusty vias and things that look like broken traces next to ICs. At a quick glance here's some areas that very clearly show corrosion.

I don't plan on integrating the SCA connector to a separate variant - not unless the carrier board doesn't work :) Running ZuluSCSI firmware, it should bench the same - about 9ish MB/s read, if the host can go the distance. Half the devices I plan on using it for only do SCSI-1 and, as such...

So, a while ago I designed these, and they've finally been cleaned up and tested enough for release (well, some variants): https://github.com/GeorgeRudolf/GBSCSI2 Why: I wanted a board done my way. Figured I might as well. I can get drives for my countless janky UNIX workstations, the...

It's not uncommon for the CPU card slots to be cracked on some machines that use CPUs mounted like that. Maybe check the ends of the slot.

Nice, glad to hear.

Sooo... The original idea was running AppleTalk over shielded cable, I changed to phone jacks to be like everyone else and that's a remnant that didn't get removed. It's very much an unfinished thing that never got built. Might as well - extra drills are free!

That's too small to be SOT-23, so I'd be inclined to say SC-70/SOT-353 or whatever. You'll still need to do a bit of bodging as the pads are gone.

I guess I could publish this. Eh. I never came to any conclusion about whether the inductance neeeeeds to adhere that strictly to the standard because I ended up never having space to set up two Macs in an AppleTalk network.

In the list of things I once designed and forgot to release is a PhoneTalk box. I have P/N PH9184 listed on that.

Both sets of pads received solder paste, but only U817 got fitted, squishing the paste on R306. When the board got reflowed, the paste on the R306 pads conformed to the body of U817.

Your obliterated U817 is probably a 74**1G08 AND gate. Need to see exactly where would the caps you're missing go to hazard a guess.

Hosiden goes on the same sh*t list as Reflektor Saratov for me, now. Soviet Reflektor LCDs are apparently sealed together with shellac, which doesn't bode well for their durability.
