In my own computer at home, I use a JDR Microdevices MCT-4S3P board. It has worked fine for me. Allows separate IRQ's for each port. The only down side to this board is the parallel ports are bi-directional and not ECP/EPP. Just after I bought this board they came out with a MCT-2ES2EP board which has two 16C650's and two ECP/EPP ports. The board will also allow you to set up different port base addresses. Other JDR boards which may be of interest: MCT-4S3P, MCT-4S.
