Whenever possible (without cleanup) having the sources of the disassembler part would be great to add that to my HP41 bus tracer. And for implementing FI output, only one pin is needed, just the Output Enable to the driver. The driver input can be tied high so you control only the OE whenever you want FI to be high. There is no need driving FI low, it is normally low and this allows other devices driving FI to take their share of the bus. Regards, Meindert |
