4 KR1802IR1 ? RAM 16x4 (D60,D61=sheet2=palette, D62,D63=sheet4=keyboard)
1 KR1810WG72 uPD765 FDC (D70=sheet3)
1 KR580WI53 8253 baudrate timer (D33=sheet4) (/CS=/CS53, A0,A1=A0,A1, D0-D7=AY0-AY7=PPIpa) (/WR only, no /RD) (CLK0,CLK1=WGPTCLK=16MHz/n, see sheet3) 1 KR580WW51A 8251(A?) usart/mouse (D34=sheet2) (A12=/CS, A8=C/D)
1 KR580WW55A 8255 PPI (D17=sheet2)
1 KR512WI1 MC146818 RTC (D19=sheet2)
1 K573RF4 27512 EPROM 64Kx8 (D31=sheet2) (BIOS/BASIC/BOOT/AMSDOS)
2 K573RF2 2764 EPROM 2Kx8 (D62=COLDAT=sheet1, D65=VDKEY=sheet1)
1 K155RE3 27S18 PROM 32x8 OC (D69="Af"=sheet3=floppy) (dummy FP0..FP3, disk /GATE, to D72 count --> DW --> FDC)
2 (KR)556RT4 27S20 PROM 256x4 OC (D28="M"=MAP14..MAP17=sheet2, D67="R"=ROMEN/RAMEN etc.=sheet1)
* The part numbers printed on the chips may look like "KPxxx" (cyrillic) instead of "KRxxx" (latin).
* As mentioned at chipdir, KR1802IR1 is similar to AM29705, but '''NOT''' the same (the AM29705 has four additional data pins).
