@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...

From ten years ago: ZipMacPlus™ Amazingly enough, all the pics documenting the process in the original thread remain intact! https://68kmla.org/bb/index.php?threads/zipmacplus%E2%84%A2.26752/ Cliff Notes recap: Don't recall if this converter design is correct or...

LOVE IT! Great work, had something similar in mind back when @MacEffects was developing the clear case. One suggestion, not pickin' nits here, love it as is, but if interested in further development: Take that fabulous adapter to your local big box home tinkering store for comparison to a round...

Back on topic of the history of Apple's NuBus implementations: Found a Dock II board in the pile and have identified the quartet of Bus Transceivers from TI in the Block Diagram above: 74ACT16651 - 16-Bit Transceivers And Registers With 3-State Outputs - mouser.com 74ACT16651 at $14.64 ea. So...

Cool, let us know how she reacts and what you think might be good. Pic is an end table lamp, so arms too long, but illustrated the notion very nicely I think.

Work was slow, so I read up on the history of French (and Italian) Cuisine. Looks like the Medici Myth has been thoroughly debunked. Very interesting to read about those who developed, documented and codified so may schools of cuisine and spread them to other countries.Wikipedia level though it...

French food is Italian food once removed. ;)

YOWCH! :eek: Grease up all exposed surfaces of person with cocoa-butter before even painting with latex. 😬 Now that we have low voltage LED light fixtures, it might make sense to have a pull down light fixture counterbalancing your pot washing pull up faucet? Thinking dentist's/surgeon's light...

Wow, didn't realize folks were so actively pursuing this kind of thing? Thanks! I was thinking a castellated PCB was a higher/multi-level version of an interstitial adapter, but it refers to castellation of thruholes used to make contact? I've been hoarding an advert for a patented industrial...

YAY! storage corral sections of shelf platform nearing completion. Bending warped castoffs to my will. Gotta find my doweling jug, shims won't do it below, but bolts will above. Doweling seems a lost art, rudimentary if exacting woodworking skill and a good, low budget TinkerTip I think...

That! < TLDR > However for me the exercise is more an exploration of the "artwork" that is a Logic Board's routing and "seeing" how all the components fit together within the copper Labyrinth. I can't "see" those connections on a conventional schematic, nor do I grok the code that you navigate...

ISTR there being STIL(?) files released in the 3D Printed Objects thread at the MLA for printing your own?

Morning musing of the day: This section of my Rev.A's HALs ought to be fairly easy to isolate from the State Machine HALs, no? Thinking in terms of socketing that section of the board and doing a PCB that would be a plug in replacement for them? Conversion of their I/O to match that of the TI...
