RAM-CART 128 K 7400 - 1 7404 - 1 7402 - 1 74174 - 1 470 Ohm - 2 4k7 - 1 470 KOhm - 1 10 uF - 1 * 47 uF - 1 TANTAL * 100 nF - 1 This two condensers should have as small [upłynność] as is possible. This decide about getting of current from battery 3V (when the power of computer is turn off). [upłynność] - I don't know how translate this, so I describe it. This is when charge is lose, I think. SRAM 128Kx8 (628128) diode LED - 2 (red, green) RESET - button This is local reset. When computer is hang up you should press it, and next press reset in computer. P - switch dual (contacts P & P' are switched at the same time) O - read; Z - write D - two silicon diodes (100mA) with maximum high back resistance.
