New Cirrus still makes the cs8900a
And the 74LS139 is pretty widely available.

The only thing you'd have to do was etch a double sided board. It really isn't that tough.

Some Radio Snacks still have double sided blank board and etching kits in store.

If you want I can go look round for one.

New If you want a double sided board, best way
if your time is worth anything is to use a proto board shop. Sierra Proto Express will do 3 double sided for $96; if you only want one, Spark Fun will do them for something like $2.50 a square inch.

yeah, but the Embedded Ethernet Board is more than just the cs8900a. It makes it so you only have to wire in the address, data and read/write lines.
