I've been slowly progressing on this build but figured I might as well share it.
This is Hese's recreation of the coveted A3000+. It's an AGA Amiga 3000 motherboard with a couple of additional goodies such as an Amberless flicker fixer, multi-input auto video switching, AT&T DSP support, and a backplane with built in Prometheus PCI bridge board.
Beautiful matte black solder mask with ENIG (gold) plated pads...JLCPCB made and typical fine quality I've come to expect from them. Hese's routing looks great too, the L/R audio circuity layout is symmetrical, nice evenly spaced traces and vias that all appear to be properly snapped to a grid, ground pours placed everywhere that was practical... it's all very pleasing to see for my mild OCD.
I forgot to take pictures before starting, so here's one I took after mounting the chip RAM.
And here it is as of last night. Except for the poly caps, all of the passives are installed and most of the logic is done. I always wait to the the larger caps last so they're not in the way. Tonight the logic should be finished and I'll be moving on to installing PLCC sockets next. I absolutely loathe installing SMD PLCC sockets by hand, but I loathe the idea of soldering the hard to find custom chips more... especially the DMAC-04/RAMSEY-07 I'll be using.
I've already got a spare 3000 chassis that I received in a trade, it's in somewhat crusty condition but except for a missing hard drive sled and 2nd FDD sled it's complete. Fortunately the front bezel is still really nice. I'll be dropping it off to have it media blasted and powder coated soon.
I've already got the entire BOM here, so I'm certainly looking forward to getting this finished!
