My version also includes a simulated "Disk Ready" signal derived from the Index signal which seems to work ok. The PCB design is poor,I didn't really understand IC bypass capacitors at the time, so they're just randomly scattered over the board. However it seems to still work ok, I haven't had time to do a redesign.  Also, it doesn't provide power to the floppy drive as I was worried that the +2A PSU wouldn't be able to take the stain - I read that the +3 had a larger supply to support it's disk drive. Last issue is that the PCB is a millimeter or two too wide and gets in the way of the Power Supply plug, so it has to be wiggled a bit to make it fit nicely. Anyway, use at your own risk - enjoy!
