FYI, I just received a parts EOL notice from Digi-Key on the 74ALS646 chip
from TI. This chip is used in the Dual-IDE boardÅ .not sure if itÂ¹s used in
any other boards.

Many of the parts used on the Retro boards are no longer
manufactured.  However, large inventories of glue chips exist among
many suppliers, especially those in the Far East.  More worrisome is
the limited availability of some of the larger chips; e.g., 6583,
uPD7220, MC68030RC, ... <br>

I agree. It should be no problem sourcing for a while. This is what keeps Unicorn and Rochester Electronics going.
