This 4-bit with Schmitt-trigger input to decouple the control signal /RD, /WR, /IORQ and /M1 from the bus can be used (IC22A).

 The IC17A (74LS688) serves in conjunction with S1 and RN1 as I/O address decoder of the assembly. The 8 /CS signals for the SRAM-IC are formed from the ECB-RAMF-activation (IC17), the /CS decoder (IC15) and the CMOS buffer battery voltage monitoring (D1, D2 and IC15).

All IC with blocking capacitors are 100nF X7R-5 (0,1 uF Tantal is also ok, please be careful with polarization) provided. This is absolutely important.
