PIC diode tester

I am looking to build the PIC diode tester described on the site. I would like to expand the project to test more than one diode at once.  Looking at the schematic it looks like it uses 4 outputs and 1 input from the 16F84.  Looking at the datasheet for this PIC, I could expand it to test 2 diodes at once as the PIC16F84 has 8 outputs and 5 inputs.  Although I would like to test more than two diodes at once, are there any PICs out there that have more outputs and inputs?  I could just use a bunch of PICs but I think it would be a neater solution if I could just use one or two PICs.

Thanks in advance.
