I recently bought 64K (and 256K) of cache.
The 64K is 20NS (256K 15NS). The problem with it is that the 486 hangs at WAIT... when internal and external cache active. I assumed that the TAG piece was bad since the seller said it looked bad (it was just faded). I used the TAG bit from the 256K pair and.. the same thing! I haven't tried the 256K pair, until my puller comes in the mail.
Someone have an idea?

Also check the jumpers for correct amount of installed cache. Try to set the slowest cache timings.

Its supposedly "automatic", and there is a set for amount and it is correct.
