Industrial PC? Go with an older system, like a PIII on a BX chipset. The last boards to have ISA slots were based on the VIA KT133A chipset, a relatively low performance, low stability chipset with compatability problems. The BX was the most stable, compatable chipset ever produced. I believe Intel was considered the most stable board producer. An SE400BX2 could use a PIII 1000E slot 1 (not 1000EB).
