Any Full 68040 Upgrades For Powerbooks, Besides The 5xx Series?

2300c MoBo has both LCD connector types on board and supports PPC upgrade for every Duo ever made, whatever the original equipment LCD lid. GS250/TB is my favorite config.
As for full 68040 upgrades, search the forums. Some of the gang got SMT replacements and upgraded PB190s (to run A/UX?) with them, IIRC.

The problem with the 1XX series was the CPU was on the same card as a bunch of other chips for video, RAM, etc... So a 3rd party would have had to engineer a whole new replacement card for the 1XX.
the 190, I dont know if they ever had a 68040 full upgrade for those or not. most likely they got a 5300 board and called it done.
also, besides the PB100 and 190, I think the whole 1XX line were all 68030s.

Bunsen and a several of the gang sourced a batch of package correct 68040 replacements for SomeBook or Other as I recall. Might have been Blackbird proc card rework, dunno, somebody will chime in.
As regards the 2300 Duo upgrade path, it's the ultimate Swiss Army Knife of Upgrades: Driving any LCD, utilizing the Trackball and OEM SCSI HDD or its own IDE flavor controller. I wish I had instructions or a list of contents for the upgrade. My guess is that the 2300's Heat Spreader/Chassis was included as part of the upgrade? ISTR an entire bottom pan being provided for some of the in-between upgrades. Some lucky folks got to keep that and the old MoBo to use their Dock as a full system when the upgraded better half was out on the road. [}

The Duo 280 was an LC'040. The all the other Duos were '030s. Except for the 2300, which is PowerPC.

I am aware of that on the duo. I was speaking for the PowerBook 100 series

I'm just wondering about the parallels between the Powerbooks and their PB Duo Cousins. I need to see their release dates, chances are they came out at about the same time.
PB 180 & Duo 270 - Last of the '030s laptops
PB 500's / PB 190 & Duo 280 - The only '040s units
PB 5300 & Duo 2300 - Start of PowerPC Machines
It is known that the PB 190, PB 5300 and Duo 2300 are related to each other and release at about the same time. But there was some time between the PB 500 series with two releases (PB 520 and PB 540) and the PB 190, and the Duo 280 was released somewhere within this time.
And the Reign of the '030 in laptops (some 17 years well into the '040 desktop era) was because of energy concerns and physical size of the '040 not being doable until it was shrunk. I know in some old Dells (Inspirons & Latatudes) PIII Units used the large Desktop PIII in their early releases until Intel shrunk the PIII and more PIII Laptops came out. Not too long ago, I repaired one such Dell and thought to myself, "Damn, they used a full sized CPU in this thing? I swear!" A couple of years later I repaired a younger model and found the PIII there being the smaller one. The problem with both machines was that the CPU Overheated and cracked, though still working, it exhibited a strange behavior: When on, it would run at full speed for a moment, and then slow down to a crawl for 5 minutes and then speed up again only to slow down again in a repeating cycle. Somehow the silicon crystal of the CPU cracked along the clock area on both CPUs. Replacing the CPU fixed them.

In brief/off topic, chipset components in the 5300 are more related to the 190 overall, they're considered one generation in the '040 to PPC transition era. The 2300 and 1400 are nigh on identical, being the next gen offerings along with the 3400c as the high end of the lineup, featuring migration to the PCI/PC-Card architecture.
The largest difference between 2300 and 1400 was provision for moving the TREX PCMCIA controller to a docked upgrade. The ECSC Video Controller capable of driving the 800x600 LCDs of the 5300ce and 1400 was dumbed back down to to the pin compatible, but 640x480 limited CSC of the 190 in the RoadApple hobbling tradition for the low end offering.
Apple hated the very notion of providing a PPC upgrade path for the Duo line, they wanted migration limited to sales of full PPC 'Books. Avoiding a class action suit by three generations of Duo owners promised a PPC upgrade path was the only reason for the 2300c to have been developed at all. Gotta love its versatility, especially the SCSI/IDE controller combo for the internal HDD.
NuBus architecture PPC PowerBooks are my thing. The Mustang Prototype, a 5300 with the 11.3" LCD of the 1400 shoehorned into the lid of a 5300 is my Eleanor.
Dunno where it fits in on the development timeline though, 5300 is a sideline interest. I've been hacking at the margins separating the 2300 and 1400 for at least 12 years, since the heyday 'fritter in the Dr. Bob/Eudimorphodon(Gorgonops) era.

Yep, it was a NUpowr 167 CPU daughterboard, Newer Technology - PowerPC 603e - 167MHz - 8MB RAM
I appreciate that thought, but that is literally the only one they don't have. The 550c enabler is literally not on the interwebs, I have looked everywhere, and the people I have contacted here that have a functional 550c have never gotten back to me, so it is indeed impossible to get anywhere. I've been wanting to dissect the difference between that enabler and the 500 series enabler for some time.

I have two blackbirds with PPC cards. The one is apple official, the other is Nupower.
The nupower one is unstable at best. crash/bombs, etc.. After it warms up its fine. (not caps, various logic boards and PS adapters, all do the same thing).
Then the apple official one works great. Even has the PowerPC emblem on top of the bezel. I found it dirt cheap on ebay, it flew under the radar a few months back.
Since I got nothing to lose, I was going to drop a 200mhz PPC chip onto the nupower card and see how that worked. I got an IBM CPU card that has a 200mhz 603e.
