PowerBook 1400 case screws!!!

[Snial]

Late last year I bought a PowerBook 1400cs/117 on Ebay which was mostly working. That is, it had just enough RAM (16MB); a 750MB HD that seemed to still work; a display that is a bit dodgy, but can work. I then bought an IDE to SD adapter; then bought another spares and repairs PowerBook 1400 because it looked like it might flesh mine out a bit and from that I got an 1400c display and another 16MB of RAM (but the 133MHz CPU doesn't work reliably). However, this then left me tantalisingly with not quite enough of a PB1400. So, in the meantime I kept scanning ebay.co.uk for a keyboard; CPU and heatsink, which I finally have!

Yay! So now I have a second PowerBook1400cs which will boot (it's well ugly!). However, strangely the case has no screws to hold it together and I think I've already managed to crash it a couple of times by pressing on the case in the wrong place, so I was wondering if anyone knew what screws it needs without me having to dismantle my other PowerBook 1400?

Is this the laziest question ever on 68KMLA? In the meantime, here's a couple of pics of the horror show that's this Frankenbook ;-)

Actually it looks much better here than in real life!

That screen doesn’t look half bad for a passive panel! It’s been well kept.

Thanks! It's a strange screen. It starts off basically just grey, but if I adjust the contrast well down, then it can be made to work acceptably, though it can also suddenly start to go bright or fade after a period of activity. it's actually the same screen as in this thread:

However, I swapped the screen with a PowerBook 1400c screen from the PowerBook featured in this thread and slowly I've been building up that PowerBook to the point where it can almost function as a complete unit (I'm waiting for a 45W PSU, I was using my other PB1400's PSU here). Actually I see you did comment on that thread too and I have yet to take the screen apart!

OK, Well I decided to remove the screws from my other PB1400. The answer is they're all M2 screws:
6 x 4mm (front), 3 x 6mm (middle), 1 x 9mm (back).

but the 133MHz CPU doesn't work reliably

Is that the one I now have?

I only know the 133MHz CPU didn't work reliably, because you discovered that! Beforehand I didn't think it worked at all!

Yeah, it’s a bit odd. Definitely a marginal connection somewhere - potentially the CPU needing a reball, which I can’t do

ISTR that it's the cache chips that fail on these CPU cards. I'm sure someone will chime in to correct me.
