I have been lead to believe (through discussions on comp.sys.att), that there is a new WD controller, for the most part pin-compatible with the existing chip, which will allow 9 head operation. Several people have reported using this to allow their AT&T 7300's, which are normally limited to 67Meg formatted capacity disks, to fully utilize a 130Meg disk. It might be an interesting exercise to see if the 2090 could be adapted to use one of these new chips. -- ---------------- Michael J.
