![]() ![]() Terribly slow logic, not to mention power-hungry and easily upset by noise. ![]() At this point it's really hard to resist to buy this thing, especially if the price is low and my wife is not around me (the last two facts are combined by NAND what means I have always a 3 of 4 chance to get the toy) To this minimal setup I can connect several chips or devices to play with.īut, again "like a child", if I stumble over interesting things, suddenly thousands of ideas flying around my head how this thing can be used for. Currently my setup is even RAMless, only a 8k EEPROM is connected to the upper 8k running small programs.Īdressdecoding is done with a 74HC138 along wit a 74HC00 and a 74HC04 as "support" chips providing the possibility to combine and invert signals if needed. By now I play on a big breadboard with a W65C02S running "slowly" with a 1MHz can oscillator to reduce the risk of timing and noise or ringing problems with all the breadboard-wires. Saving board space will be important much later I think. I'm still in the phase of learning how things fit together and like a child I start playing with bigger building blocks. I saw that this chip is a pudgy one, but working on a breadboard or standard euro-pcb cards, this fact is not really important to me by now. ![]()
