Greetings from San Francisco, new member here so thank you in advance for the input and discussion on my topic. My Apple 1 board has many correct chips and dates codes but still searching for the most correct ones (the big one will be to replace the 6502 with a MOS white ceramic). For those of you who might have time, please open the two attachments and examine the current chips and date codes. I would be interested in which chips should be updated to reflect a 1976 pre-NTI board. Also, what week in 1976 would be the cut off for a correct pre-NTI board? The table below has an X in the last column when I think that chip should stay and a "?" to indicate a possible change.
I'm also aware that this type of replica that has all correct chip makers and exact date codes for 1976 only appeals to a very small group as most are satisfied with just a working replica. But I am hoping that those who like this type of challenge will help me. Thank you all!
