    2. Mac II, Quadra & Centris

      Just think, having a Quadra 950 in 1992 would be like having a Mac Pro today… except with more slots, more expandability, and on-board SCSI!

    • I built with the default options (just "make all"). It appears debugging is on by default, so I do have debugging on.   I did built with the latest version. I forked your repo so that I could make updates to the README with some instruction updates. But my fork is up to date with your repo.   Is the "TX" debug port just a RS-232 type signal? What baud rate did you use? I can hook up a TTL receiver and try to capture some info, if that helps.
    • This one worked out well. Replaced 99% of caps and re-soldered wires going to the base and the image is on. It will not power on without source attached though. On the board the main IC is a proprietary one but also other parts/drivers are long obsolete. Best path is to get a similar/same board as a donor. EHT still has got "wining" sound even though I soldered centre rod under pressure but image is acceptable.
    • Thanks. I was going to swap motors next to rule it out. The rails have been cleaned and lubed, so no issues there I don't expect. Is there an info resource head demagnetization?
    • No, it should be working at the point you're at. I don't have the firmware in front of me, but as far as I can recall the weird INQUIRY response is normal. Basic bus transactions must still be fine to get the info from the Nuvolink utility, so I'm guessing it's not anything with your soldering.   Are you using the most recent commit in the git repo, and did you compile with debugging enabled? I'll get my board out tonight and see if I can get some additional stuff added that might be helpful in figuring this out.
    • Earlier this summer I placed an AM/FM radio with its antenna extended, right next to my Mac 512K or Mac Plus, and at some high-end frequency I could hear every action of the Mac. I could hear loops, disk access, and so many other noises.   I tried the same thing with the Power Mac G3 and could hear almost nothing. I think that radiation is a function of not only shielding, but also miniaturization of components.
