A cheapo Altair 8800 style computer using a Z80 - (part 3) - Adding RAM and the deposit function

In this series of videos we make a Z80 computer in the style of an Altair 8800 for people/budgies who can't afford £4k+ for a box with a few LEDs in it. In this video we add some RAM to the computer and make the deposit module on a couple of breadboards and run a tiny test program. ------------------------------------------------------------------------- If you want to build along at home you'll need: 2 breadboards 1 62256 SRAM (mine is a HM62256BLP-7) 1 74HC245 1 74HC32 1 74HC08 (used in the run function) 1 74HC123 1 8 way DIP switch 1 push button 10 1k ohm resistor 2 22k ohm resistor 1 1nF capacitor 1 10nF capacitor 8 LED a selection of breadboard wire
