I was never in an Apple 1 club, but I do own an Apple 1. I bought it back in 1981; actually traded it for a then-new Epson MX-80 printer. It isn't complete. When I got it, most of the chips were missing. I have replaced everything but the 2519V shift register that serves as the row buffer in the video circuit. For the past few years, I have thought about taking a counter and a RAM chip and building a small board to replace that function.

I came across a photocopied manual somewhere along the line, and burned new ROM monitor chips for it shortly after I got it. I have the cassette interface, but no ROMs for it. I don't have any software for it, though that would be nice to have if I ever got the thing running.

Hi Glen,Welcome aboard!

Hi Glen,

Welcome aboard! We have the PROM code for the cassette interface recovered and it is available for download. The 2519 is a tough one. Many surplus IC houses claim to to carry some of the rare Apple 1 IC's but I've heard stories of getting wrong parts. By the time the Apple 1 was being sold the 25xx series IC's were already becoming difficult to aquire.

Do you have any photos of your Apple 1? Has it been modified in any way?
