- depending on your supplies, if you are working in the 3rd millenium, maybe you also need some adapters (eg. USB/RS-232), "ancient" cables (eg. old fashioned DB-9/DB-25 serial cable), and maybe a DB gender changer (no pun intended)
- EEPROM programmer for 28C32 (or larger)
- you can even build one with an Arduino
- 28C32 blank EEPROM
- common hardware tools (eg. screwdrivers)
