well if you dig around you should be able to find a bunch of older 
equipment and quite frankly, they will work for another 10 years or more 
on average. They are more out of fashon than broken of worn out.

For example computone no longer wants to support there serial port cards 
and I think a number of them can be found on the resale market now.

The cost of USB based serial concintrators is now getting not that bad. 
For a small cluster this may be a reasonable altenitave.
