service manual USA for HP 8012B

[hnjmkl]

Hi, I'm looking for the HP 8012B US version service manual, I have P/N 08012-90005 Germany with the schematic that doesn't match the circuit I'm trying to repair, in fact it refers to S/N 1633G00491 and above. The S/N of the 8012B is 2325A17931 made in the USA, thank you for any suggestions.

Hello,
At the end of that manual (pages 113 and beyond) there are changes documented 12 February 1981 for serial numbers 2110Axxxxx on. That might explain the differences you find in the schematic.

Link to the xdevs site with that version of the manual: https://xdevs.com/doc/HP/8012B.pdf

the recommended manual from 1980, unlike the one I downloaded previously, largely corresponds to my circuit being repaired, it certainly helps me, pity about the low quality of the scan, probably the original was already dirty.

Artek has much better scans

You can e mail and ask them if your version is in their scan.

unfortunately it is not what I need, however I am not the only one to complain about lack of documentation for the 8012B, in particular the coverage for S/N 2325A XXXX

The non-correspondence of the 1980 manual compared to the 2325A series is evidenced by the poorly made puzzle using different manuals, one with a metal spiral and the other with a plastic spiral, congratulations HP!
