RE: HP-67 Card reader capacitors replacement
The caps aren't tantalum, but they are polarized. The marking is visible on the cap in the middle of the pic, and in the schematic. So you're looking for an axial electrolytic caps. The ones on my 67 are marked 4 volts. The third cap on the right with the red band is marked 15K and measures 15.7 uF using a handheld DMM. This is different from the schematics.
