- I have a 386-33 made by TCS which uses a SIS chipset. This will not work
- with the Cyrix 387. I think its because the Cyrix has to run in the
- synchronous mode (unlike the Intel, which can run asychronously). Its not
- really a bug but a lack of complet emulation. It works fine on most clones
- but be sure you can return it if your MB can't use it. My dealer informed
- me of the problem after I tried it myself. There was an extremely
- detailed review of all the coprocessor chips on this net a month or so
- ago that you should get hold of if you want the real scope!
