the source code now works 
as do all animated relays and semantics are quite good now

just a hardware build and debug
perhaps add a small flash port for the ic
perhaps a bootblock and upper flash part




you need a cheep 4 way usb hub you can do surgery to
some very small 2 pole pcb mount relays and one one pole
some smd diodes anti chatter
a pic 16F84A  a 20mhz crystal two 15pF ceramic caps 
a few 10k resistors 
some 5 buttons and ribbon cable 


schematic revision 0.8

all relay functions active models in proteus 
done
code set up and start to rework 


here we have 4 X memory usb keys  mounted to one gotek individual 
but on release mount to pc and mount the new selected to gotek
only one drive at a time to gotek all the rest are pc 
if you press reset all 4 usb keys are bound to the pc

rules

no drives open in the pc as windows etc before reset 
a reset will unplug and plug back in all usb to maintain order in the stack

ill add too the code but framework is their

easy now the schematic is done

the pic code is compiled in C with picc
the cvcc control is just high pulsed low when ever a new card is selected 
a 4 cards use the simple pulsed vcc supply to the card

so heavy surgery on the hub and some cleaver wires
