I picked up a TI486SXL/40 CPU and it came with an interposer board. I suspected it was for cache coherency. I did not use the board, because motherboard I used already had support for a TI486SXL/40. I just did a build with a CH-386-33A/40A motherboard with an Opti 82C391B chipset and 128KB cache. I decided to try the interposer board in this system to see what it would do. I am currently using a 486DCL/40 CPU with no options enabled for A20M, BARB or FLUSH input and I have had absolutely no cache coherency issues. I would be interested if anyone has any information about this interposer board.
