Rejuvenator is now working together with Lucas/Francis after the mods where installed. The system works fine until I try to add my Comspec hard drive controller and Seagate drive. This conbination was working fine before the Rejuvenator was added into my system. The amiga simply won't get past the request for the kickstart disk once it has read the kickstart. I suspect that it has to do with the overall noise that the hard drive has added to the system. Also even without the harddrive installed, the system will only successfully boot with one combination of a crystal (18.32MHZ) and 74LS74 chip. Any and all other combos (ie. 16 or 20 MHz crystal with 74ALS74,7474,74 ,74F74,74S74, and 74AS74)won't boot period. You have in the past mentioned that the noise can be measured with a hi speed scope on the power lines of the Lucas board. I don't have access to this equipment,but are the some areas on the Lucas or Francis boards that I could add some additional grounding or perhaps capacitors to reduce the noise? I also know about your upcoming buffer expansion device. I assume that this may reduce noise from the hard drive controller and drive back to the amiga motherboard/Lucas/Rejuvenator components? Somebody here told me that this would only stop additional noise if the design of your buffer board included a SEPARATE power source to it ie. the buffer would not get its power from the amiga power supply. Is this correct?? As always thanks in advance for your continued support of your product Thanks Ron Stein
