OK, what was the rbf patch to make nos9 6809 level II v3.2.3 work with existing hard drive drivers? And what is the CRC of the patched module, please. The patch I have (changing $7C5 to $21, CRC $732705) won't boot. Willard -- Willard Goosey goosey at sdc.org Socorro, New Mexico, USA "I've never been to Contempt!
