actually I'm using only 5v from an atx power supply

and a strap between +5  and +12 so that +12v is replaced by +5 for the 4164

the idea is to reinstall 2 regulator to have +5v generated by the cbm 8032

and +9v available (I'm planning to use a commodore datasette)

I dont want -9v anymore it is not used by the 4164 and is not uses 
anywhere else

so the 7905 is removed "for ever" :)
