Macintosh SE/30 logicboard recreation (thread revival)

Hi all,
I created a 3D STL model for the RESET and INTERRUPT button right angle support (for use with the ALPS SKHCBHA010).
It doesn't have the bottom prongs but I found out that it doesn't affect the firmness much.
This model will fit on the original and the Bolle board.
You can download it over here:

3D Printer settings:
80% infill
0.2mm quality
no support

I am in the UK and am thinking about ordering some of these. Basic green boards with the bottom side populated from the BOM/Parts Placement. I have at least one donor board that is in pretty bad shape.
1. Is anyone else interested in one of these - looks like minimum order is 5?
2. Can anyone give me a quick rundown of which options I need to specify from JLPCB - board thickness, etc...?
Thanks

I am! I'm in the UK too and have been meaning to get one of these new PCBs for a while.
@CircuitBored, @cannfoddr, I believe @Kai Robinson might have one or more available - you might want to drop him a PM.
No, just a board file with a BOM.
I have my boards on the way, and I have an old mac IIcx board that I will be harvesting all the parts from. I will let everyone know the progress as I'm curious to see how many of the parts required will be available on the IIcx board. It looks like most of them will work when comparing images of an Se/30 board and a IIcx. Of course I will be ordering dip sockets, PGA cpu, pga socket, roms seperately.
None left i'm afraid. I won't be putting an order in til after August either.
I think anyone that claims to have lots of ASICs for these should probably be treated with moderate suspicion, unfortunately. As far as I know there's no reliable source other than bombed boards.
For those who are interested;
I measured the ferrite beads located at L22,L20,L19,L18,L17,L16,L15,L14,L13,L12,L11,L10,L9,L8 with my VNA.
Hereby a sweep resistance output from 1Mhz to 500Mhz.
M1 is at 100Mhz 92Ohm with a low Q factor.
Taiyo Yuden FBMJ4516HS111-T is matching this curve.

Beside this, i found some beautiful good fitting replacement parts for L1 and L2 which aren't on the BOM list;
L1 HALO LD11-0246FLF
L2 Laird Performance Materials 29F0303-0T0-10

Bad VRAM? Does it go away after 10 minutes?
Kai,
any plans to order more - I am in UK and now have 2 possible donor boards - just got a new one on the ‘finds’ thread. We could go 50:50 on something maybe?
Alternatively, might be the video PALs, since the pattern has a repeating structure (I think the socketed chips above the RAM sockets.)
