I spoke to HP about it a couple of days ago. The drive itself is
a Philips, but HP wrote their own firmware. The data sheet shows a 1Mb
buffer, and it is 1x, 2x and 4x in reading and 1x and 2x in writing.

They have not yet decided whether to release the programming details
- they mentioned the possibility of charging royalties for it (in the hopes
that someone will come up with a commercial product). The other
possibility was that they would just put the docs on their BBS. They had not
decided, and suggested that I check back in a month or so. Anyone who is
interested in this might want to give them a call and respectfully suggest
that putting the docs on the BBS would be a much better thing to do :-).

The Windows software that comes with it does not work with Win95 -
that will be released at some later date.
