| From: Nicholas Bodley Subject: HP-9100 Documentation Date: January 24, 1998 I have a book published maybe 15-20 years
ago, perhaps a "source-book of computer
architecture". Iirc, it has some fairly-detailed
explanations of the 9100's internal architecture. Hope I
can find that book! Also, issues of the H-P Journal of
that period (late 1960s?) had article(s) about the 9100.
Granted, these are not schematics... |

Staudt Subject: schematics of 9100 Date: January 25, 1998 Those HP people tend to destroy papers of
devices they donīt support any more... |
| From: Alex Knight Subject: HP9100 schematics Date: January 26, 1998 While not a complete schematic by any means, there is useful information on the HP9100 contained in the US Patent granted to HP's Tom Osborne, Patent No. 3,623,156. It has a few block diagrams and some general schematics of several key areas of the design, and some interesting theory of operation information. Unfortunately, the complete image of the patent is not on-line on IBM's patent server (they do have a text-only abstract of the first page). I will try to scan images of the diagrams to post on my Web page, but this will take some time. The copy I have is probably to fuzzy to run through a OCR program and re-create the text. But, if you have access to a local Patent Office you may be able to get a good copy, or order one from the places that sell them. Still looking for a 9100 - if I can ever find one then I'd be interested in "reverse-engineering" it using scopes, logic analyzers, etc. and documenting the results on the Web for all to see.

Staudt Subject: schematics of 9100 Date: January 27, 1998 > Hi Ulrich, I would be very interested. I have a 9100 that works and a 9120 that doesn't. > Regards > David Green Hi David: No problem to make a copy, shipping cost is US$10 airmail or $5 surface. Please send to Ulrich Staudt Louis-Ferdinand-Str. 50 b D - 45472 Muelheim / Germany And donīt forget your address! Regards ulrich |
| From: John Larkin Subject: HP-9100 Date: January 27, 1998 James, Thanks for the response. Yes, I'm still trying to find schematics, service manuals, and even design documentation (pcb artworks, algorithms, whatever)-- not to just repair my calculators, but also because this stuff is historic and may already be lost. If you have any 9100 docs, or can lead me to someone who has such (especially a member of the original design team) I'd be unspeakably grateful. Good engineering is art, and every artform has a period where it begins, flourishes, and is then superceded by the next form. The age of the transistor lasted only about 10 years, and produced two masterpieces: the Tektronix 547 oscilloscope and the HP9100 calculator. There are lots of 547's (I have 14) and manuals around, but NO documentation on the 9100. If you can help, please e-mail me or call anytime. John Larkin 800 473-4418 jjlarkin@worldnet.att.net |
