Here is my coco3 with:
NoCan-8MB
Custom keyboard
    Got tired of trying to fix dying coco3 keyboards...:-)
4-high stack of hard-drives
    Just using the top one for now
    The next two drives are the normaly used ones
    Bottom one is for backups
3-high stack of floppy drives
    /d0 = 80 tks DS-DD
    /d1 = 80 tks DS-DD
    /d2 = 80 tks DS-2HD or quad-density
Not visible CD-R on shelf above
PC-jr. monitor - with sound
Modified floppy controller (to do QD floppies)
    Without case but has clear plastic cover.
Tiny-IDE controller
    Follow the IDE cable back
    Sitting at an angle w/ frosted cover over the chip (fragile!)
PLCC FlashROM - 28F020
    Has 2 different CTRL-ALT-RESET pictures, one bart another a logo.
    and 6 different CTRL-ALT-RESET boot-nitros9 options
PC-power supply
    With lots of extra connectors and adapters!

Now showing:
The CD and Zip drives with their own IDE board, $FF5X.

Here's a close-up:
Shows that NoCan-8mb board
    That LED sticking out at the left is the 2MHz indicator
    The other cables are serial and parallel ports
The 40-pin cable that the floppy and IDE controllers are plugged into
    is going under the coco game slot where is another row of square pins attached
    This "flips over the rows" and orients the pins for direct plug-in
    All of my controllers have square pins soldered over those tinned connectors for reliability
    This way nothing can slide crooked and cause really bad challenges :-)
The floppy controller is the +5v & +12V one
    The LED's sticking out are hi/lo-density and side0/1 indicators
    The controller chip is that Fujitsu MB8877A one
    And of course a re-wired ROM
The keyboard connector has been removed and placed at the end of an 10 inch cable
    That the keyboard cable plugs into (wow my english teacher would croak).

Custom Keyboard:
Not pretty but very functional
Yes, the reset key works
    The cable goes from double-row 40-pins down to the extended coco keyboard connector
        What? another use for spare IDE cables? Yes!
    On the backside (other row of 20 pins) is reset wiring and spares
So, rebooting OS9/NitrOS-9 uses the bottom 3 left keys
This was punched out in a machine shop, key-switches and keytops added in about 1990 and stored in a box until this year
