eBay 400MHz Wallstreet II?

I've had a few wallstreet/pdq's identify as 400 as well- i think it's a bug in certain builds of the system/system profiler- usually after a reinstall they show up correctly.

Great link. Second one 404s though.

WS/333MHz is not on that collection's listing. "Delusions of Lombardness" might have been on the money after all? I figured it was overclocked, never thought about the possibility of a CPU Card compatibility between the two. I wonder if the system bus of the WS would need to be overclocked, if the Lombard's CPU tolerates the mismatch, or might have been designed to support the PDQ's clock in development?

Gotta check part numbers in the service source specs. [ ]

IIRC the faster WS ran an 83MHz bus which is how you ended up with the wierd 250(ish) and 292MHz clockspeed in the top of the line model... at the low end of the lineup, the 233 was at a conventional 66MHz. For the sake of god knows what it was standardised at the slower 66MHz bus speed in the PDQ (or WSII as some refer to it) and the CPU multipliers changed to create a 266MHz and 300MHz mid and high end model.  The Lombard maintains the 66MHz bus still, but ran at 333Mhz or 400Mhz, so from that standpoint it makes it look slightly feasible that pinouts and socketry allowing, a Lombardy type upgrade is possible.

By the sounds of it people have tried it and it has indeed worked at least on the PDQ, and I can only imagine that for what it is worth, the discrepency in bus speeds may play some part in why it works seemingly in one series but not the other. Now in having said this, it brings me to ask what of the old nasty and unloved original 233 WS? Is it possible that as it runs a 66MHz bus anyway, that a Lombard CPU may indeed still have worked? This is going of course only on a fairly unsubstanciated assumption that the incompatibility between bus speeds is the deciding factor.

Interesting read, Schmoburger.

Odd that they would standardize the bus speed at 66MHz, at least from a performance perspective. I'm sure it made sense to the bean counters. Now those unusual CPU speeds make more sense.

My research shows the original 233 Wallstreet running at 66MHz. A speed Apple seemed content with for quite some time. That always annoyed me with the G4s; their FSB speed never increased past 167MHz despite ever increasing processor speed.

When I reload 9.1 I will see what CPU speed is reported. I was so excited to 400MHz but the P/N on the CPU card squashed that dream. Ironically, I bought this machine for a no-muss no-fuss writing machine where I would leave it as it and not worry about it.

Apple didn't let it get past 1:10 at least, but it indeed was slow. Admittedly, the Pentium "800MHz FSB" was really 200MHz and quad-pumped, but still.

Indeed the 233 was always 66MHz across both models. Then yes, 66MHz was standardised in the PDQ and also the Lombard... being raised to 100MHz with the Pismo which from memory also had AGP graphics. More strangely at least again from performance perspective is that a 66MHz bus speed that was also in place on the beige series G3 desktops even during the tenure of the original 83MHz Wallstreet, and this was not raised to 100MHz until the B+W G3 happened, by which time the WS and PDQ had both come and gone. I've always been perplexed as to why they saw it fit to have a faster bus on the portable than on any of the desktop range. The mid really does boggle at some of Apple's decisions of days gone by...

I reinstalled 9.2 and System Profiler still identifies the CPU as 400MHz, despite the P/N identifying a 233 chip. OS9 moves along quickly enough and I use the machine primarily for writing so 233 or 400, my needs are met. The geek side of me wants to know why but for the sake of efficiency I'll just accept the mystery.

Schmoburger, my mind boggles at some of Apple present decisions. They certainly had some doozies though. My brand new PowerBook 190 arrived with white paper sticking up against the LCD from inside the bezel and the main board failed within six months. As a 5th grader I was squarely accused by some of breaking it, something for which Apple should apologize!

That is strange though, that the portables had a faster bus for a while. Perhaps that thought it wouldn’t be noticed with non EV processors.

Benchmark the WS - Norton's System Info is a good test.

I'd be interested in what TattleTech and The Gauge Series might have to say about the machine.

Could be a resoldered CPU (have you checked?), as 266 --> 400Mhz overclock is unlikely. 

Tattle Tech- great name. I'll find Norton and those other system snoopers and see what the verdict is.

Byrd, not yet. I have had too many other demands on my time so far this summer. I have only removed the cover plate and found the part number. From the top there isn't any evidence of re-soldering. I don't have any experience with soldering but I would imagine that if the chip was replaced with a 400MHz version, the top wouldn't look so pristine?

It does feel snappy, snappier than my beige G3 (266) before the G4 upgrade.

I still have not taken the processor out (waiting for a few parts to do an upgrade) but I did load TechTool Deluxe. Its impression of the machine?

400MHz PPC 750 and....100MHz FSB.

It just gets stranger and stranger. It is an eBay machine so who knows what its previous life was like. I suppose it could have a Pismo board in it. I will have to check the machine ID next time I have it out.

I would like to put a Travelstar drive in. Has anyone here actually had the magnet/sleep issue? Unfortunately, at the moment it will bomb on startup every now and then. The fan also comes on when I plug it into AC (internal batteries are flat). Is that typical? I reset the PMU but I haven't noticed anything different.

To save my credibility, I just realized that it couldn't have a Pismo board since the I/O & reset methods are very much Wallstreet.

Fan coming on is normal as far as I know, both PDQ's I have do that.

I'm seeing this too. I swapped a 300 mhz CPU card into a 266 and Apple System Profiler reports it as 450 mhz. Any idea where this is coming from? It's not PRAM because none of the PRAM batteries in these work anymore. I did a PMU reset and there was no change. Maybe something in OpenFirmware?
