It is present in Imagewriter drivers >= 2.5 and LaserWriter drivers >= 4.0, and not in any third party drivers (including SoftStyle's HP Thinkjet driver that I have). Any drivers that intend for Hypercard to use them MUST implement the PrGeneral call. Second: edmoy@violet.berkeley.edu asks about odd address alignment on the Mac Plus versus the Mac II. The 68000 has an exception condition raised when an odd memory reference occurs. The 68020 does not. That accounts for the difference in behavior you noticed between the two machines. Jon
