      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!

    • Great! Thank you for the help. I'm going to order the parts and boards today for the 1.5 version. I suspect I'll end up with extras, although I need more than one (for other projects).   My machine's floppy drive literally lost its magic smoke today so I'm really with no way to boot my Mac.    I just cloned the repo and I'll see what I can figure out while waiting for access for to the hardware.
    • Quite happy with the results, I kept the cover off to compare. Used 64oz of 3% peroxide, few table spoons of oxy, in a clear plastic storage bin, with a few landscaping  rocks to take up volume inside and the rest filled with water. No streaking at - the slight variation on the picture is just water I wiped away before taking the pic.   Front, keyboard, and back panel are in waiting for the sun tomorrow.
    • Well, it’s not like you didn’t try!  
    • Curious....   In the stack of Ti machines there was another 1Ghz that booted and had sound, but was in a really cosmetically bad case. Read up on the R&R, and it didn't look bad, so I swapped the logic board from the machine with sound to the machine with no sound.   Everything works, except the sound! Machine acts like it did before- volume keys show volume up/down, sound control panel works. No sound out of the headphone jack or speakers.   I guess the next step is to put the pulled logic board into the cosmetically bad chassis, and see if it starts to work there. I should also figure out how/where the speakers are connected, I guess, and see if there's some kind of short.   Ideas welcome...
    • The most I get is, upon powering, is that most pins have a +2V rise with power applied that does not change. Pin 1 has +5V deflection that does not change, either. There is certainly no rise in signal from pin 15 after a second or so, or any time after, just the +2V when the machine starts. In essence, I suppose this thing really is toast! I verified vs. the EGRET on my LCII to make sure I had the correct readings and, sure enough, Pin 15 behaves just as you stated with a voltage jump.
