I am trying to convert 8 bit binary from a adder I have physically constructed to bcd, is it possible to do this with logic gates?

Can you program all eeprom with an arduino or do it manually, and are they interchangeable if you just adjust the connections?

It's definitely possible, but would be extremely tedious. It took me 18 gates to implement a 4 bit converter. It would take 7 of those blocks cascaded to implement an 8 bit converter.

The algorithm is called Double Dabble and many examples are available on the internet.

Nothing much has changed since last time you asked.
Most manufacturers’ parallel EEPROMs are pin-compatible. If don’t have and can’t borrow a programmer there are firms on the internet that will do it for you, but they might not be cheap for one-off.
As last time you asked it was “homework” then perhaps your college would own one.
