EQUATIONS
  ; Umwandlung Bank Select in Adressleitungen:
  A16 = /CAS1 + /CAS3 + /CAS5 + /CAS7
  A17 = /CAS2 + /CAS3 + /CAS6 + /CAS7
  A18 = /CAS4 + /CAS5 + /CAS6 + /CAS7
  ; Chip Enable Signal für SRAM:
  /CE = CAS0 * /RAS * AKT
  ; Output Enable Signal fuer SRAM:
  OE  =   /WE
  ; Write Enable fuer SRAM: Invers zum OE
  WE1 = WE
  ; Latch Enable fuer 74 573:
  LE = RAS
