sTAYED HOME WITH A BUG TODAY AND HAD THIS BUG . . . (%&(&(*#& cAPSlOCK!!!!! Playtime in AI: Address lines are indeed contiguous between the Soldered DRAM and SIMM. Saw that right off, but felt like seeing the whole picture so I kept at it.. Strange that A0-A10 are implemented in Bank A...

It's EVERYTHING in the Bucket. Some components throw off more heat, some less and all have varying amounts of heat tolerance. Yep, PSU and A/B components would be the worst offenders for BTU production I'd think? Dunno what the weakest component would be in terms of heat tolerance? In modern...

Nice! Adapter bolted up to the A/B without a hitch? What fan did you use? Not surprised at all that a modern fan would be much quieter. Was your OEM fan's noise all that objectionable? Any fan noise at all from an SE would have been objectionable to some users moving from the Plus or Minus...

Liquid cooling is for CPU only in that i7 hack and in any conventional rig, no? He says that the fan that removes heat from the liquid cooling rig in the usual SE position? Looks like that's the only case cooling installed? He says "The exhaust air doesn’t even feel that hot!" THAT hot in...

OK, been looking at this as a plumbing diagram, continuity testing would be the way to go. Haven't gotten any further in my refresher read, but hoping this is still the case. You're still using this adapter in testing? If I'm understanding it correctly, you designed this adapter for the case...

Found this diagram of MDU memory controller from the IIsi and IIci in my backup of MLA attachments: Note how Addressing for Bank A (DRAM ICs) and Bank B (SIMMs) are discrete connections to each Memory Bank. That's been my concern, if anything like that is going on in the Sonora Memory...

@max1zzz is working on upgrading LCIII memory, but he's stuck at 4MB in Bank A for the moment. https://tinkerdifferent.com/threads/breaking-the-36mb-ram-limit-on-the-lciii.1344/

What machine's flyback is that, no cage apparent? The fact that temp readings are lower on flyback in comparison to CPU temp doesn't matter. Now you're sampling a point more closely aligned with machine cooling state that's unaffected by processor activity. Readings are much nearer to point of...

@alxlab Just did another stream of semi-consciousness brain dump in the SE Borked tangent post. Testing the efficiency of your ductwork designs against Apple's kluge may be in the cards? Would a modification of your baseline bracket design converting it to the SE's A/B mounting points be...

@max1zzz You haven't answered my question: is your utility reporting RAM installed in each bank specifically or are you going from system totals? Which utility are you using? Need to see the schematic the adapter you're using I think?

Read again? Thought what I said was that BBS and Forums were far superior to newsgroups for cooperative ventures, blogging is a step backward into the wilds from BBS and Forums. Usenet rocked. Great point about linking to a blogged summary, well organized and concise from an invariably messy...

Am I the only one left from olden times when documenting projects with Q&A developments in forum threads was a big deal and the way to go for stuff like this? Blogging was great back then for self absorbed drones to disappear out on the fringes of the web where we could ignore them. Not all...

Yeah, but it's OT here and probably deserves a dedicated discussion in hardware. That's most especially true of the A/B reloaded/upgraded notion I think. That'll likely branch off into its own topic as well if I can I get it going. ;)

https://tinkerdifferent.com/threads/macintosh-se-or-se-30-fan-bracket.976/post-11398 THX! That'll clean up this topic nicely. Proposed title bolded/italicized

@Kai Robinson @max1zzz I see you're online, could one of you please move my entire Cross Flow Fan: SE cooling inplemented right and then borked? tangent to a dedicated hardware thread?

Much more useful information would sampled by attaching that probe to the closed, front side of the flyback heat shield/radiator cage. @alxlab could use that config to test the OEM fan cage part to his two improved versions. That should prove quite interesting. edit: easy title search at MLA...

Pics and add'l info along with particularly crazy tinker notions appended. 🤪

Check the pics that'll be added to keep them all aligned in that one post. Mine has a horizontal neck board.

Fabuous work! Can't wait to see results. Still wondering why they'd block Bank A when over expansion in SIMM Bank B would be the more obvious problem to be addresse, just as in case of LC. /Occams Razor

None of the brilliant, outside the boxers at Apple could get that through one particularly thick skull with blinders attached. Hyperfocus on design to the detriment of function is a major failing in a project director. Reality distortion is a multidimensional field, deleterious thought well...
