I recently picked up an AST four port, minus the octopus cable but
with docs at a local electronics parts reseller.  It was $40.00 with 2
16450 uarts.  They are socketed on the AST card.  These guys buy out
all the old equipment when a company upgrades or goes out of business.
If there is one in your area that is another source for these cards.
