    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!

    • Never mind, I have already found a screw kit.
    • Got my stuff (except the DB-9 cable) and a prototype is working!   The caption for this video is:   "Confinement Day 75"    
    • I turned my attention to my IIsi over the weekend (still can’t figure out the voodoo to bring back my 2400c  ) and played with the Applied Engineering QuickSilver card I recently acquired with manual and floppy!     The 32k static RAM Cache is the most interesting thing about it as I have other adapters that add an FPU. I decided to run some benchmarks via Norton Utilities System Info 3.2.1 (System 7.0.1) with the original clock chip and overclocked to 25Mhz with 50Mhz clock chip, with and without the card/cache and FPU:  
        A neat progression in performance improvement (essentially doubling over stock). The best performance run “Macintosh IIsi/25 + FPU/Cache/D” came when I remembered the Memory Control Panel Disk Cache trick of setting it to 1024k to use up the slower soldered on motherboard 1MB of RAM with disk cache forcing the video memory, OS and all other apps to use the faster RAM in the SIMM slots. If you have the memory a pretty significant improvement on its own!    CPU comparison with the other system in this version of Norton Utilities System Info:
       
       
    • Thank you for the story!   What a happy outcome. Direct gift to somebody who will restore it and share it with the community. You love to see it. 
    • That's a really nice G3 tower. My former 8200...ehh, all I can say is good luck
