Sure, I've been planning to share my BOM anyway so this gave me a reason to stop dragging my feet. The custom chips and DB-23 sockets came from Individual Computers, just about everything else from DigiKey. I also reused some harder to find parts from my original motherboard--the delay-line IC, 22-degree angled SIMM sockets, self resetting fuse, RTC chip, RTC crystal, RTC trimmer, and the audio jacks.
I had to purchase some NOS 74F841s on eBay because they don't appear to be available new anymore. Those are used for U216.
Below is a link to my Digi-Key BOM in Excel format. In many cases it's cheaper to buy larger quantities of the passive components. That's why you'll see some line items with a much higher quantity than required--because it costs less than buying only the needed amount. I also padded many of these inexpensive passives with spares since it's only a couple cents more and easy to loose these small SMD parts.

I should note R179 needs to be subbed with a diode when using a coin cell instead of NiCad--which hopefully everyone does. That's the diode at line item 85 in my BOM.
I hope this helps!
