Trying to recover 67's prerecorded magnetic cards

[Joe Horn]

I used to have complete success using the "Write-Protect Defeat Card" that somebody published in the Journal forever ago. To make the card, either cut it as shown or simply cut the whole lower corner off at a 45° angle, leaving the upper right corner as shown. Just push that corner lightly into the EXIT side of the card reader until its stops. This will make the card reader think that the card coming in from the other side is write enabled.



This trick only helps if the card being written to is magnetically functional. If its timing track is damaged, or if the data area drops bits, then you're out of luck.
