SE/30 conundra

First of all, I need the missing manual. This new toy is acting for all the world like it has a blown fuse. Is there one inside the SE/30 PSU as there is that of the IIsi?

Second, this thing feels weird and looks odd. How smooth is the SE/30 case supposed to be? It has a little bit of texture, so it's not quite glossy. But I don't remember my SE being so smooth that  I could see the lines of the gussets of the internal framing members or what feels like flashing ridges along the mold breaks raised high enough to be this obvious to sight and touch.

Inside the case it says 815-0960  REV (A) which is in a tooling plug located dead center in the Y shaped handle reinforcement ridge. There's also a tooling plug directly to the right in the corner that says (TP) along with  several other blank plug (_) circular flashing ridges scattered about as usual.

It just doesn't look or feel right and its beyond dead, so let me know about the odd textures, ridges and that |)@^^>[[) fuse!


TIA,

RATS! I pulled it apart and found the fuse in the PSU right about where I expected it to be  .  .  .  but it tested good.  hmm

Re: SE/30 conundra

An SE30 that you have not shown the motherboard..... Is it recapped?  It will be dead if traces and caps are issues, and of course cap goo once it starts can make it irratic.

Good luck.

Re: SE/30 conundra

I traded a dead 605 board in a Performa 475 case for a recently borked SE/30. Gotta ask what the symptoms were, but I didn't want to ask about the smooth case over there, just in case, so to speak.

He tried to recap the /30 with a bad soldering tip. I fixed one broken trace, it's ugly as hell, but the tester says the connection's good.

Re: SE/30 conundra

<facepalm>

I plugged the wrong cord into it, no wonder it seemed like the fuse had blown. Fan starts up, no other activity. I'll take some pics. There is one thing I've never seen before on the solder side:

C61(small brown) Runs next to/parallel to L21 (larger black), but they're bridged by a component like the one at C69(medium ivory) VERY ODD. I've never seen three tiny SMT components bridged directly together in a U shape. I can't tell if it looks like rework or not. Could it have been a factory boo-boo or a standard fuglypatch?

Dose the minimal amount of texture on the pics of the bucket look odd, or were they all markedly smoother than the front and sides of the front bezel?

Re: SE/30 conundra

Hmm interesting/unusual. I've never seen anything like that. I have/have seen some smooth case stuff but its extremely smooth... looks like some kind of hybrid you've got there but it's hard to say. I'm stumped but it's really cool or sure. I wonder if maybe when they shot the unit in the mold, perhaps it was under filled by the slightest amount, so it couldn't get the full texture. Just a guess as it's what happens when we do a short shot here at work with our molds.

Re: SE/30 conundra

Looks like a pretty normal se/30 case to me.

Re: SE/30 conundra

Interesting, I guess the production machines all had that high ridge along the mold break edges? Do all three of yours have three different texture gradations, knobby tired bezel face, street radials on the sides of the bezel and all but slicks on the bucket?

I remember my SE having a lot more texture than this. Anyone got (TP) molded inside? I thought there might an outside chance it stood for "Texture Prototype" with the way this looks and feels, but I guess not.


edit: just checked it against the Classic, it's got a quarter or less texture than that of the Classic's texturing. How do your three SE/30s compare to the texture of a Classic Bucket, Cameron?

Re: SE/30 conundra

I have some pretty large photos of two different SE/30s. Use the "Download" link for the large sizes.

Re: SE/30 conundra

Great pics, the socketed version almost looks like mine, your light tent/lighting effects may be a factor. I'll take some natural light shots and upload them full resolution/size. Given his experience with the production process, maybe hap will see something else that's curious in them. He's got me thinking that the tooling might have been worn out causing the lack of texture and inordinately raised flashing. This doesn't look or feel like a part that would pass muster in a production unit, but quality control (low yield in the case of the Twiggy Drive) has been problematic more than once for Apple.

From what I can see in your pics, there's more texture on your cases than mine. How do your SE/30 buckets feel as compared to a Classic's bucket? There can't be a huge difference in texture between mine and a regular production unit, snake88 would have noticed because this is one of the pair that he had. But after years and years of working in just about any medium imaginable, my sense of touch has been very well refined after having been well above average from the start. The Mk.1 eyeballs passed muster unassisted at 60 for license renewal, still correcting to 20/16 as well, after having started out at 20/10 during production, burn in period and first drivers license screening. ***

Re: SE/30 conundra

Yes, the SE/30s are a lot smoother than the Espresso Classics.

Re: SE/30 conundra

That answers that. Do your cases have three different levels of texture, front, return & bucket? I think I can almost see the evidence of subterranean framework around the power switch assembly in your pics. Mine has some dirt and grime collecting low spots, which lend support to hap's bad shot observation.

Having an example of one of the fugliest cases ever to make it through QC is cool in my book too. I'll take some pics outdoors in the shade over the next couple of days before & after oxycleanng the bucket.
