My experience was using a IIfx ROM successfully in a SE/30. I've included an email i sent to LowEndMac.com last month so we might kill this thread. This is pretty far off topic for PCI mac discussions. :-) Please be welcome to address further enquiries directly to me! -- >Date: Sun, 9 Sep 2001 01:08:57 -0700 >To: [EMAIL PROTECTED] >Subject: Lowendmac contribution: 32-bit clean ROMs in SE/30 > >Hi >Your SE/30 page wants input from people who have replaced the SE/30 >ROM SIMM with a 32-bit clean ROM SIMM.
