Oh, they're cassettes? I thought they were modules that contained the Memory necessary to run them? That way they'd be useful in general as memory expansion. That'd drive package price up, but the Stat package especially would be portable sans cassette player. Just one expansion slot in the...

Killer find! Interesting to see that the programming modules include the expanded memory required to run them? Gotta love the late Sir Clive, hadn't looked into his life or known of his multidisciplinary achievements before this, though I'd ordered his Z88 notepad computer from England almost...

Cool, hadn't seen those before. Looks like I should get one for pastry prep. Once in a while when I get home from work I'm in the mood for a sweet treat, so I whip up some vanilla shortbread cookie dough for an immediate snack. If I have milk in the fridge I sometimes remember mom times past...

Hiya, Welcome. BGA rework sounds like fun, if way beyond my abilities. Have you looked at doing interstitial PCB conversions from package to package on a board as yet?

Newfangled kitchen/general purpose development, circa 2.5 millennia B.C. Updated in metal ASAP. Son brought Ulu/Cutting Board back from his Nols Alaska adventure a decade ago. Love it, need to oil the board again. https://en.wikipedia.org/wiki/Ulu#History

Hence, the "have been" caveat, Kai! ;) I've been having trouble finding much of interest back there in terms of development/tinkering with hardware since the mass migration of talent. Hope you folks don't mind my tagging along, hopefully a side order of crazy added onto the menu for this place...

Just in case height limitations bites your butt, I just had myself a blast playing in GraphicConverter on the Lombard. :) As your custom SIMM would be rotated 180 degrees in this configuration, any fli -floppery would be done on the riser card which could be higher. If there's interference...

I think most here, definitely the founders, have or have been active members of the MLA. Cable introduces too many problems at RAM access clocks. Works for NuBusexpansion at 10MHz. @max1zzz named it GhostSIMM already, GhostSIMM III which is more appropriate. My nick for it was tongue in cheek...

Looking at MegaSIMM3, I'm wondering if the bottom row of ICs might be interfering with the backside of the SIMM connector?

Cool! Can't ask for more than that. Yep, that cropped up a month or two ago in the MLA PM thread I think. :eek: < waves white flag furiously > You're way ahead of me on that stuff . . . see above. :rolleyes: Cannot believe you've had any time at all for this what with the arrival of...

Way cool, max!. Looks like it might fit. Print it out at actual size, rubber cement the paper to cardboard, cut it out, stick it in the slot and measure clearance. Haven't got an LC case handy, but if it's equal to or shorter than the FDD you should be good to go. If it doesn't fit, the diagram...

Indeed, but some of this doesn't make sense to me at all. Per below, it would seem "Ranks" of memory would be more appropriate, no? With address lines contiguous between DRAM pads and SIMMs it looks more like just one Bank with 5 Ranks supported. Makes sense as Sonora is described as an amalgam...

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...
