Hp-41C card reader - dead

[teenix]

Figured it out.

I used a narrow piece of metal and slip it between the contact terminal block and the surface underneath the top cover. This moves the two one way locks away from the top of the contact block and the cover slides off.

cheers

The upper part (I/O cover) is simply slipped over, but there is a plastic lock in the inside in the middle. The service manual recommends to insert a spatula into the I/O slot. It also warns to be careful not to damage the I/O contacts.

Best,
