Source for TI-59 Magnetic Cards

[Tinue]

The card looked familiar, so I checked my set of old cards (the TI 59 itself has died, sadly). Indeed: The card was there. I bought the TI 59 ca. 1981 in Switzerland.

It does have a much lighter color compared to the regular cards, and as far as I remember this was always the case. It did not change color over time, in other words.
