And… it’s alive! I ended up socketing the chips, and swapping in the VIAs got it going. Thanks again to Bolle for doing this - and also for revising the board so that the latest rev has the right footprints.
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.
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...?
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.
Off-topic question to people assembling boards: are y'all scavenging from bombed boards, or is there a source for NOS ASICs that I'm somehow missing? I've been looking far and wide for a replacement for an SE/30 GLUE chip that might be malfunctioning.
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.
