The SLC has a 16K cache as opposed to the normal 8K, which Robert >Mitchell mentioned. I'm confused. My understanding is that for Intel 486 chips, SX means "no floating point unit", but is still 32-bit. For 386 chips, SX meant "16 bit". If the SLC is based on "486SX technology licensed from Intel", then the SLC ought to be 32-bit. Now, if it were based on 386SX technology, that would be a different story. It would also explain why Intel was so generous to IBM.
