I'll try to wrap my head around that when I can examine the traces. Do you have a utility that reports how much memory is installed in each of the two banks or is statement based upon reporting of total memory detected from both banks? Might be important? It sounds like you're combining RAS...

Modified salt box design facing south with (horizontally hinged at top) clerestory casement windows to vent hot air in summer? Consider setting your joists (or just treated furring strips) on 2" rigid foam insulation? Usually installed vertically between concrete foundation and ground, but it...

Have you got a schematic of your breakout board. Extra eyes looking at it might find any problem should there be one? Doubt you'd see activity. Got pinout of Sonora? Comparison to MDU might be helpful. Since the LCI was developed from the LC bloodline, it may be entirely different. If Sonora...

Very, very cool! ;) That should help a lot in moving more air more easily. It might not feel like that to the touch if compared to the first version with machines side by side do to pressure reduction in the boot's more efficient transition? But that will likely also help by reducing...

Back on topic: @alxlab have you looked at the round to rectangular transition at all? Thoughts?

However, he didn't put much stock in vents for his precious Mac's bucket design. He was badly mistaken in his assumption that deodorant was unnecessary as well. IMO your quest for thermal disbursement for the 68030 is a solution is a search of a problem. Can't think of a single case where...

Sweet, what's the resolution and how do the pics compare to the eyemodule2? I'll have to hunt down the pic of my WA setup for eyemodule2.

SD Card Camera, details please! I went with the Handspring Visor for its long awaited expansion slot. Eyemodule 2 color digicam walked out of the store with me and the Visor that day. Got one shot of the smoke pall running across the sky down Broadway from Lispenard St. on 9/11 with it by...

Thanks for jumping in with both feet, bud! I know work has you well and truly knackered. :) So much information! Looks like the one RAS line thing for the eight chips on the IIsi board in my diagram is correct after all? One review question: I have a suspicion that we figured that addressing...

Not maths I think? Seems a nomenclature kinda thing. You may be mixing computer numbers (binary) up with IRL decimals? You need to have A11 implemented to address 64MB. That makes A0-A11, twelve address lines. Diagram is from the everlasting SIMMspender hack aimed at torquing Bank A of the...

:ROFLMAO: . . . no wait . . . SE/30 has WiFi, IIfx should be easier, six times as many backplane cover plates for antennae. :unsure:

HRMMM? Doubtful that you'd have any timing issues at all cropping up? That's a unified 25MHz system bus, so only a ridiculous amount of latency from buffer or active components could be problematic? Traces could be a meter long on that clock I think. Maybe capacitance issues? Try isolating and...

@max1zzz wondering about how much memory the Q605/475 might address using one of these puppies without jumpering Bank A to a better version? Got a guess? Can't get to anything to give it a whirl any time soon.

A little off topic here, but hard to imagine there being enough headroom for much of a heatsink in the SE? PowerBooks use a heat spreader, transferring heat to the metal chassis*** or is part of the metal chassis itself as in the Duos. Might be able to have an aluminum spreader laser cut, but...

LOL! No other questions about this one? :p That's a manual inject FDD just sitting there temporarily. The original autoinjector was acting wonky at the time. Worked fine, installed it for a while. You can push the floppy in with your fingertip most part, once in a while a I had to poke it with...

Out of the crypt, another blast from the past! My pet IIfx became a IIfx/CD Stealth Style When I'm playing with the Pet IIfx, it's usually with lid popped and NuBus Cards strewn about. The Optical comes in handy. Hanging batlike, out of sight, out of mind, dwells the HDD boot drive in...

@max1zzz forgot where I posted the new pic of the SIMMexpander with active components, but here are a couple from the iFrog collection. Still haven't found that dang project box. Found a this juicy bit of the docs in it though: Four single or double sided 72pin SIMMs, I'll bet you're...

Thanks, love it! Looks like my PCB proposal might have been a bit too wide to fit the headers between the connector and the Controller? Is termination power provided on the SCSI Controller Chip with no connection made from it to the DB25 on the Plus? That was my assumption, I see you've...

Here's where things get interesting, Breaking the reverse engineering necessary to as few building blocks as necessary: 1) determine the NuBus Clock generation circuit in the Rev.A 2) isolate the HALs implementing its three state machine 3) Isolate the HALs implementing NuBus Transceiver...

Assuming the gray is an extended view of the outlet? Rectangular exit would extend to meet the corners of the bucket's grill, well past the screw bolt hole locations. From memory, bucket grill is taller on the Y axis and narrower on the X axis than the circular fan outlet? tube at bottom and...
