1 × z80 CPU DIP40 & socket
1 × 32k SRAM & socket I'm using an alliance as6c62256
1 × 8k EEPROM & ziff socket I'm using a CSI CAT28C256 EEPROM but only accessing 8k - can be expanded to use the 32k
1 × 3.3k & 2.3k resistors I used 3 1k in series and 2 1k in series which works fine
1 × 8mhz oscillator can package 4 pin you can use any clock speed the z80 can handle but be aware of baud rates
1 × push button for reset
1 × 68B50 Serial Chip & Socket I'm using Motorola brand. you can use the 6850 without the b but be aware of clock speeds
1 × USB To TTL FT232RL adapter This adapter handles non standard baud rates which is great for using any clock of your choice.
