Go for Pentium I's or higher. A Pentium-60 would be just fine as a thin
client, as long as the motherboard supports PCI. PCI support is the
real kicker here. It is true that 486's certainly have the CPU oomph to
be thin clients, but not many of them have PCI. A 486 with a PCI slot
would in theory be just fine, but the PCI support in 486's was said to
frequently have issues. That said, if running 10Mbps NICs is OK in your
situation, and 486's with ISA or EISA are what are available, then try a
few out and see if they work out for your situation.
In my experience, thin clients need to have 32MB DRAM, though NFS swap
will allow you to do it in 16MB on x86's. They don't need more than
32MB, but it obviously wouldn't hurt anything if they do have more.
