Help, I need help!!
Ok, I don't really deserve help, as what I have done is just too stupid, but anyway...
I am still trying to fix this HP37E. And now I got that 32E for parts (Thanks Stephan!!). So I started working on it again. And.....I droped the chips out of the frame. I had numbered them before, but it came of when I used alcohol to clean the contacts. :(
Now I am not really sure wich chip goes where and wich way round.
Does anyone have a picture handy? What I *think* is correct is this:
The big chip is inserted so I can see the "AMI" at the bottom-end (opposit of the LEDs) of the calculator. Then one silver chip to the top (towards LEDs). This one is missing one pin, the pin that is on the top left (towards LEDs and towards calculator middle). The other silver Chip is the one at the bottom-end, looks the same, has also one missing Pin pointing in the same direction.
I am pretty sure about the silver ones, as I can see where there is no mark on the flexible circuit-board from the missing pin. Are those chips both the same?
In the middle of the two silver ones, there is a little black one. I placed it, so that the hp logo points to the top (LED side) of the calculator. Just like the logos on the silver chips do.
Sorry for beeing that stupid...
And thanks for your help.

Harry
