Quick recap what I’ve done to this day with Amiga 4000D. Found this, mostly by accident, from local ‘ebay’ for 200€. Just by pure luck, it was located next to my home town only 30 minutes drive. As I could promise, I’ll be picking it up in less than an hour, it was mine. Poor guys inbox must have been filled in just minutes.
It was in running state, but by no means it was fully working unit. And for extra 20€ I got (faulty) 68040 CPU card and for 150€ fully working Cybervision 64/3D. Inside there was 68EC030 CPU card.
And as expected, it had the most common faults. Leaking caps, varta damage around RTC and broken SIMM clips. Couple traces around audio circuit was also busted with opamp. But nothing special.
And here it’s running fully equipped for the first time. 3D printed sd card carrier for easy swap.
And as you can see, already new addon waiting to be assembled. It’s PCI daughtercard designed by Hese, so instead of only Zorro or ISA cards, I can add PCI cards to add networking, USB, Graphics card etc.
Daughtercard assembled and programming firmware with Raspberry Pi as JTAG. Did this before soldering rest of the connectors so it would be easier to debug, if the card wasn’t working.
And then some real life testing, CV64/3D is found and so are NEC USB card and RTL8xxx network adapter.
But then I learned after this point, that to get those PCI cards to actually work, I’d need some PCI graphics card which would then provide DMA memory for most of the other cards to work. Oh well. I did find some 20€ S3ViRGE PCI card afterwards, but before that I already learned about opensource Z3660 project which is basically CPU accelerator, RTG (graphics card), Soundcard, ‘virtual’ SCSI emulator etc. And I was sold, but more about that in next post.
