OK, I went ahead and booted it up and it reported it was 33mhz. I looked at the crystal and it was indeed a 16 something crystal..however it looked like someone replaced it with that one. Do you think I should put it back to 20mhz?

The bios/rom read it as a Power Macintosh 8500 

Sure. It's also worth noting that the card itself has 300 mhz crossed out and 400 mhz put into it's place. I was curious, so I looked underneath the heatsink and it was a a 300mhz EV Engineering Sample with 1MB cache. So I guess they overclocked it. 

it has a copyright 1996,1997 on it. and something that says 09782. Possibly a date code? Dunno

Unfortunately the HDD was DOA. It's completely dead, so I'm trying to swap HDD pcbs on it to see if that works. (I tried a direct swap with another one and it booted, but I think the head is messed up or something) In other news, I booted the Mac up with MacTest and the following came out of...

I picked them up in a big lot with a lot of other things, so it's hard to say. 

Oh I know that, I'm curious about the model number there..the AP2430

I honestly thought nothing of it when I picked them up. I saw a bunch in a pile, saw they had 68040 processors on it and was like "Could always use those!" Weird...

Last in the odd series. Found this PPC without a label, looked inside and found a few fun things.

Continuing on from the odd motherboards I picked up.  What does that number mean? Thanks!

Yes, it was near the Cupertino Apple HQ

Interesting, thanks for the info! It was dropped off at a local computer recycle center.

So I looked for the model #820-0380-02 on the motherboard and came up short. Odd thing is this one is a 40mhz 68040,  but it  looks nothing like the Quadra 840av. Any information would help!

Sorry,  yeah...I was thinking of another thing lol. Thanks for the info guys!

So I found this locally for a few bucks. I tried looking it up, but none of them have the HD logo on it. Is it the same as the high density one, just with a logo? (IE a possible revision?)

Kinda a necro bump, but in this case wouldn't it just be easier to create the card with sockets for the CPU/FPU and have the customer/buyer provide them? That way you can bypass the biggest charge of the project and all the buyer has to do is stick theirs into a socket.

Interesting, thanks for the info. I watched the vid on youtube and it seems techknight really hates the board made by Apple haha.

I was wondering if anyone had tried to mod their original portable to include some sort of back light since obviously the upgrade kit is kind of a rare thing.

Wow looks like that was it, never knew there was a interlock switch. I feel like an idiot....thanks!

Sorry I know this is like beating a dead horse, but I recently picked up a regular Mac Portable for a few bucks at a computer recycle shop. It's in quite good condition minus being a little cracked on the battery compartment casing. So far I've: recapped the entire board, replaced the battery...
