Maybe not a new information.

I just figured out a difference in the 30 series.

Maybe some wrote it in the forum but i did not find it by search.

I have two 32e both in bad condition, so i hought i could mix the best parts. One has soldered circuids one not.

The one with the soldered circuits has an plastik plated keyboard, so it looks very ougly over the time. The other plate ist made ot of metal and also more resistable against cleaning.

Both are made 1980 in Singapore, the unsoldered in 9. week the soldered in the 28. week.

Do you mean 1990?

No. 1980 Serialnumber starts with 20.

Oops, my mistake. I was thinking 32S not 32E. I didn't know HP was manufacturing in Singapore as far back as 1980.

I have a version 3 HP-35 with the serial number 1302Sxxxxx, which puts manufacturing in Singapore at least as far back as 1973.

Hello, "Doctor B" --

Here's the most recent reference to the HP-34C Spice-series design:

I'm surprised that you'd have a 1980 model with the improved soldered design. It might be the back cover from an older model on a 1982 calc. I've got non-functioning solderless HP-34C's from 1980 and 1981, and a working soldered version from 1982.

Just in case anyone is wondering if these can be fixed:

My one and only HP-34C came into my life as a non-functioning solderless one. It is now a functioning soldered one. I completely disassembled it, soldered the chips to the flexible circuit board, ground away parts of the frame that's supposed to press the chips against the board (to leave room for the solder), put it back together, and it now works.
