Apple 1 Memory Test WAV or MP3?

Mr. Vintage Apple 1, Corey Cohen, visited me on Saturday and photographed my "Weather Station" Apple 1 in great detail, as he is preparing the provenance document for it. We are able to load and run Woz BASIC but determined there may be a bad memory chip in the upper bank. I need the test program to determine which chip may be bad.

Thanks

Mitch
PS Trivia: We call it the Weather Station Apple 1 because in 1976 I created a peripheral that measured the tides, wind speed, temperature and solar radiation, mounted it on the roof of my houseboat and plugged it into the Apple 1. Steve Jobs visited me on the houseboat to see what I had done, like it, but told me to NOT write my book about the Apple 1 (a POS he claimed) and instead invited me to Apple Computer to give me an Apple II to use for the book (Computer Graphics Primer). He wanted me to give him the Apple I back but I told him I forgot to bring it. Lucky me. He offered me a job but demanded I move from Marin Country to Cupertino. I could not live in that asphalt jungle so I refused.

I'm back at my home computer, I just emailed them to you...

I'll try to upload what I have for everyone else to my website and put links here over the weekend.

Cheers,
Corey

OK I put the files on my website

http://myapplecomputer.net/programs/A1memorytest_E000%20area%20load%20at%200000.0003r%200280.03afr.wav
http://myapplecomputer.net/programs/A1memorytest_lowermem%20load%20at%200000.0003r%200280.03afr.wav

These will work on a real Apple-1 as the code is ROR bug clean. You will need partially working lower memory. If the program doesn't run, you need to use old fashioned troubleshooting to get the lower memory working well enough then you can scan for bad memory locations in lower and then E000 range.

to load
C100R
0000.0003R 280.03AFR

then 280R to run

Hi Corey, do you also happen to have an AIFF version of the Apple 30th Anniversary program? I’m still working on getting my serial to ASCII keyboard interface working on my Mimeo.

I'll post it later today.

I guess I really should put a lot of this stuff on my website. I'll try to make some time next week to make a "page" to download from but for now I'll put links here.
