To all,
I am working on another HP67 card reader.
I have replaced the gummy wheel - adjusted the fingers so the motor pulls the card through - fixed the clutch - cleaned the keyboard contacts - fixed the cracked posts.
So now I get the card pulling through nice and even at the right speed.
It gives an error on read - no error on write - and yes I will change the capacitor when I can get one today.
BUT - I tried reading the written card in a known good card reader and - error. From previous posts the capacitor only affects the read and the write is ok. I know the write actually writes something but it is not readable in a good reader. I used a good reader to write a dummy program then tried the read in a good reader - OK. Then I used the suspect 67 to write a dummy program and then try reading in a good 67 - error.
Could this still be the capacitor or do I have something else wrong?
Thanks Malcolm
