Mitch,
All the IPAS from the Yost Group work with V3 although some of the IXP's do not
take full advantage of the 64 bit color space. There is an upgrade for those
IPAS which can be downloaded from the Schreiber Instruments BBS.

In addition to what John said, you can only upgrade your routines via the
Schreiber BBS if you bought the routines via them or a 3DS dealer. If not,
you'll have to send the Schreiber folks your Disk1 original back with $25 for
handling.
However, you can update SG_I.PXP from Disk5 (it needs it) by logging into the
Schreiber BBS at 303/759/3598 and looking in the Yost section for SG11.ZIP.
It's a patch that'll make Silicon Garden work better with r3's texturing
methods, and you can get it even if you're not on the Schreiber customer
database.
