Power Macs generally have a minimum color depth of 8 bits, Quadras and earlier could do 1bpp. It's simple math. You only need 128K bytes to display 1152x870x2. To display 1152x870x256 you need 1Mbyte. It's simply that a minimal 1152x870 on a Quadra was "more" minimal than on a Power Mac. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting [EMAIL PROTECTED] "I'm a designated driver on the Information Super Highway" -- Quadlist is sponsored by <http://lowendmac.com/> and...
