    Palm m515 / BlackBerry Curve 8520 - mid to late 2000s productivity!

    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...

    Breaking the 36MB RAM limit on the LCIII

    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...

    Breaking the 36MB RAM limit on the LCIII

    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:

    Breaking the 36MB RAM limit on the LCIII

    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...

    Breaking the 36MB RAM limit on the LCIII

    @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.

    Macintosh SE or SE/30 Fan Bracket

    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...

    TinkerTales from the crypt . . .

    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...

    Breaking the 36MB RAM limit on the LCIII

    @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...

    TinkerTales from the crypt . . .

    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...

    Macintosh II Rev.A - Reversing the Discrete IC Implemented Origins of NuBus

    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...

    Macintosh SE or SE/30 Fan Bracket

    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...

    Macintosh SE or SE/30 Fan Bracket

    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...

    Macintosh II Rev.A - Reversing the Discrete IC Implemented Origins of NuBus

    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.

    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.

    Ultimate Bolognese Sauce

    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...

    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...
