Re: Happy discovery
Missed a word: ‘could’ – they could be be from 1975 ... (were they made in the 80’s??)
To test 1802s, there’s a simple set-up with some LEDs connected to the address pins a solderless breadboard and hardwire the NOP code to the data inputs.
And I have way too many 1802 so I won’t trade my chocolate ...

Wow! Really early specimens then. Thanks Magnus.
I can test the 1802 easily, the 1854s not so.
