If you want it soon, send irritating mail to >kevin@amdahl.uts.amdahl.com :-) FFP mode is the worst case. It does floating point all in software. IEEE mode at least uses the 881 (or 882). MandelVroom 2.0 has a bug in it's 020/881 menu item. You can use newzap to patch the binary. Patch sector 221 byte 0a1 to a value 0f (it was 1e). This should allow 020/881 to run on 020/881 and 030/882 machines. Rick Sterling from Commodore called me about this one. He provided the patch and had it running on a 3000 before they were released. He said it was extremely fast. This and other problems are being fixed in MV2.1.
