Oh...my...
If I may ask.. How much did those set you back?

You're right. 'Spensive. But what luck to get two such scarce 603e daughter cards. I hope your luck holds as far as their condition goes. Of three that I have bought in the last few years, only one (a NewerTech NUpowr card) worked out of the package, and it works well. One was damaged (the socket for the RAM card), and the third may yet work when I get the time to speak sternly to it.
Make sure that your RAM is fast enough (eg, 70ns rather than 85ns), and that your cache is set in the Memory CP for (32 x n)kB, where n is the number of MB of RAM that you have in the PB. You have the max. 36MB of RAM in each machine, going by your post, but if you need faster RAM, trawl these Forums for a recent discussion of sources of RAM cards for the PB 500 series.
Much luck, and may you enjoy your find.

I can only guess he means an LC PDS 601.A PowerBook 500 upgrade card?!?!I have one of these in my Mystic Colour Classic
I have a 50mhz 601 in my Q700, but I also have a 100mhz that I have been too lazy to put in it. Those 601 cards make a huge difference and some people have even gotten Mac OS 8.5/8.6 to work with them. I would guess that it would be possible to get 9 to work, but I haven't found any documentation anywhere of anyone who's done it.

Nice one, I seem to have become a dumping ground for 5x0 Powerbooks, having been given a nice 520 greyscale and 520c most recently - they've both gone to good homes (iMac600 one of them!).
One of my previous posts here:

... I was lucky enough to score a whopping 167Mhz Powerbook 540c with 36MB RAM in that auction Years ago, 68KMLA member Flash! was kind enough to give he his 540c with Apple 100Mhz upgrade, and both machines are running Marathon via a serial connection quite nicely - cool to see them both hammering away at a nice frame rate

Tch, tch! It must be something that you did rather than that OS 9 did.
I can count the crashes by OS 9 on the thumbs of one foot. Four years on two always-on 500MHz CRT iMacs (before OS X was installed); on Beige G3 DT and MT, both now G4/500MHz; on an 8600/200 metamorphosed into a 9600/G3/500MHz, on three 5500/G3/400MHz, and on, and on. Even the pre-installed 9.0.4 of the iMacs behaved itself for more than a year before installation of 9.1. It supports the principal wave editor that I use, and you can believe that I should be comprehensively narked if it were to crash during a twenty-minute sound normalization, or similar activity.
Sir. You risk prosecution by the soon-to-be-formed RSPCOS9, with a branch near you, even in WA. (For other enlisted: that's Western Australia, not Washington State.)

Holy smoke! I have one of these, sitting unused and forlorn. Anyone want to buy it for $100.50?

I read '540' and thought he said LC540 (which doesn't actually exist) - sorry [] ]'>
Hey IT WAS LATE okay?

That's hardly the issue - I'm sure he wanted them for the rarity and coolness factor of owning 2 rare Mac upgrade cards. I didn't even know such a thing existed for 68k laptops.

Yes, a spot of luck it certainly would be.
Meanwhile, back on planet earth ... one of these days I'll get around to posting it on eBay and see what I can get. $30-$40 would suit me fine. (Actually, I think mine must be the 117 Nupower: that rings a bell.)
I keep my 68k machines 68k, so the first thing I did upon getting a 540c with the ppc upgrade installed was to whip it out and return the poor thing to its natural state of 68LC040 purity. Each to his own, I suppose, but in general usage, I find a fast 68k chip much snappier than a slow 603. Remember that this thing can run 7.1 Pro, or better still, a stripped-down 7.1 Pro, which absolutely blazes along on a fast 68k.
All System 7 versions are in my experience also more stable on 68k hardware. Even plain-Jane System 7.5 has proven to be solid. So there are lots of advantages in Keeping It Simple, Soldier.
