    PPC740L G3 CPU Daughterboard For Blackbird Powerbooks

    Sounds more like plan A with a side order of Plan A1 if it's based on proc-swapping an existing PPC upgrade? Plan B would take it to the next level, designing the entirely new G3/RAM card I proposed, using only a donated interconnect.

    Is your comparison to BaselineBird or to the 166MHz accelerated 603e PPC upgraded Bird? Just ran across the Pentium OverDrive, an example of CPU retrofitting of a more capable wider bus CPU to a narrow bus in existing systems. I wasn't aware Intel ever did such things themselves. The parralels to what you're thinking about for Plan B are remarkable.

    PPC740L G3 CPU Daughterboard For Blackbird Powerbooks

    No doubt, just dialing back the timeline for all but nostalgia driven upgrades. Had it been love for a first PowerBook that drove purchase decisions, that would have another story entirely. Then there are also practical reasons for upgrading rather than replacing. Before PowerBooks were released that could match the portable power of an SE/30 . I agree with you entirely about the tradeoffs, even MacWorld made sure to point those out in Accelerator reviews. So long as the accelerator was a reasonably low multiple of the cost of biting the bullet and buying a current replacement for any given Mac, the case for upgrading a bought and paid for machine made a lot of sense. That argument breaks down when OS or Processor spec. for required software versions outstrip capabilities. From the other side, accelerator upgrade path availability drove decisions of my production machine purchases from late eighties thru Y2K. G3 was the reason I opted for the purchase of a maxed out, obsolescent 1400c/166 when the 2300c, my main portable machine to that point was inadequate for playing around at WarDriving. It never replaced the 2300c/Docks home and at work bookkeeping setup. The 1400c/G3 was finally replaced when CoffeeDrinking came into vogue and HP-Mini returned me to the PowerBook 100/Duo System. At any rate, the "just because I can" and "Apple decided I couldn't do so" mindset of this project rulz!

    If it was a custom Apple part OEM'd by AMP, that makes a world of sense. If it was generally available as a standard AMP part in an existing product lineup, EvilApple conspiracy theory makes very little sense to me. G3 enhanced Blackbirds might have been competitive up to the 1400 aside from their obvious Optical Drive deficiency and crappy LCD resolution. But there's absolutely no way that they'd have remained competitive beyond that point. Even the 2400c had a 40MHz System Bus for its G3 cards. The Wallstreet's 66MHz/83MHz buses combined with 1024x768 resolutions on the latter at 250MHz, much less 292MHz would stomp a 666MHz G3 Blackbird into guano pronto. Not to mention the 512MB vs. 64MB RAM ceiling that would be a no-brainer nod to the WS. Haven't looked at Kanga spec, but it would probably be a contender against any possible Blackbird stuffathon as well. Sorry, there are good reasons I've but a couple of mobos and processor cards from your favorite PowerBook series. I'd almost certainly choose the PB190 over a Blackbird. But I'm right here in the game for your summit attempt!

    Yeah, I'm looking forward to Bolle's further input on this find. Dunno, never thought I'd ever really have to admit it, but I just can't keep up with you kids.

    Exactly, PBX is located on the solder side of the 1400 board centered between the connectors above. Processor card interconnect is definitely a direct connection to the PBX Memory Controller/Bus Bridge which handles ROM, RAM and Expansion RAM on the Logic Board. PBX itself handles the buffering. I was surprised to see no additional buffering for the 1400, in the others the 603e and PBX are all but conjoined twins. Yep, that's why I said there's probably no mystery about what's under the sticker. 133MHz and 166MHz processor cards w/cache have a similar setup. What the heck are those five ICs between the connectors on the Sonnet G3 board? I can't make heads or tails out of the designations . . . so I'm waiting for somebody who knows something about them to chime in. Absolutely, that's why I'm targeting the 1400 processor card for a 666MHz FX build. Pretty much all needed would be the CPU, the specified resistors, capacitors and whatever voltage regulator black magic would be required. That's the recipe for the 117MHz Processor card: Paralel, would shots of the 166MHz 1400 card be helpful for comparing it to the Sonnet G3 and the cache-deprived 117MHz card above? I may have a 133MHz card in the stack as well. G, the 117MHz logic board is incompatible with either of the two later Processor Cards with Cache implemented. IIRC, the 133MHz Logic Board can be upgraded with the 166MHz Card. Might it be worthwhile to figure out why the 117MHz logic board is a special case? For the first release 117MHz logic board you have to go straight to a G3 upgrade.

    Could be wrong, usually am. But SCSC and the Video Card span displays, both limited to 16bits. That's why the unobtanium NewerTECH VIEWpowr 1400/16 is just that, limited to 16bits, that's what the connector speaks. I may not recall correctly, but in tracing lines from PBX on the 1400 logic board to the Video and Card Cage connectors (15 years ago) they appeared split left and right and to be a high/low type of thing. We're also not talking about any old normal computer bus here. The funky bridged 68030 NuBus architecture PowerBook I/O setup of everything from Blackbird up to the PCI architecture 3400 was a kluge from top to bottom . . . . . . except for the Duo System, that was perfection!

    Nice! On my way to pick up the VidCard and CC/LC ThunderCache Accelerator, I realized that the 68020 to 68000 adapter may be just what the doctor ordered. Couldn't hardly be better, it's a two layer translucent PCB so I can see both sides of every trace from either side of the board! MicroMac ThunderCache + E-Machines SE Adapter = PerformerPro +- ??? edit: not as a plug-n-play solution, but in terms of firmware for a new adapter card design with the Pal socketed on adapters old and new.

    I'd go with the the AMP marketing decision theory. The Blackbird's interconnect is a 16bit part given its pin count and it was a 32bit world by the time the G3 was released. The extra 10 pins on the the 1400 interconnect above would have made a significant difference by then, so why bother continuing production for a shrinking market with more capable parts going into production. Even the modem connector a couple of inches away on every Blackbird already had 100 pins at the same time. I'll throw an the engineering decision theory as well to complicate the binary set. The 1400 part is far more robust than the Blackbird interconnect which suggests to me that even if AMP continued to produce an eighty pin part, they would have moved it into the same series as the 1400 form factor. Is the modem connector a 100 pin version of the 1400 interconnect? I put the Blackbird box away for the time being so I can't readily take a peek at a board. For the EvilApple conspiracy theorists I'll make a point that would be more obvious to myself anyway. Apple likely used a part from an obsolescent series with a different height(?) for Modem and CPU interconnects intentionally. Such would make a unified bus processor card bridging both connectors nigh on impossible to implement. THAT would be just like something the denizens of the Infinite Loopiness would do. :P edit: I don't have a Modem in my miscellaneous parts collection for the Blackbirds, can anyone prove or disprove the mismatched connector theory by telling me if the CPU and Modem circuit boards are on the same plane? Also, if anyone has a spare modem card, I'd like to have one in my grubby little paws for testing the feasibility of a two connector PCB, mismatched or not.

    PBX is the Bus Bridge ASIC directly underneath the 603e on the solder sides of 5300 and 2300c and in the same place on the solder side of the mobo underneath the 1400's CPU Card connectors. edit: does GX use PLL resistors in hardware for bus multiplier settings like the FX? If it's a later version, sounds like it's software only. Paralel's pics on p.1 of the NewerTech NuPowr 167 MHz: Looks like you can see the outline of PBX underneath the CPU in the box of vias surrounding it.

    Sweet, finally looked at email and the card and another MicroMac Accelerator were delivered today. I'll be walking over to the Rental Office in the AM!

    oooooooo That was my dream setup for a good couple of years. I had the Radius 16 and wanted the FPD SO badly! Wound up with a IIx and a Panasonic TPD/Card combo (also 1-bit B&W) with plans to get the Rocket. Worked out fine, but never did get that FPD. Tried once on eBay, but the seller wouldn't let me pick it up, insisting on getting ridiculous S&H fees. :P Got pics of your FPD with the lights on? Now I've got the Radius 16 in an SE again and a Radius PrecisionView 2150. So I picked up a couple of TPD cards, no joy yet, but I'll get one up and running some day. Way too many projects, way too little time and attention span.
