I can't seem to find the ones I thought I had. If you could copy them that would be a help. At some point I want to do an IDE to omnibus interface, looks pretty simple if one is a willing to take advantage of the 16 bit wide IDE data (yes it wastes 4bits per 16bit word). First thing I have to do is another 4k of core, the 4k I have is not quite enough to work in. The alternate is to make a RAM card using 32kx8 parts. Allison
